Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein.
The vehicle typically includes components having reflective properties such as a dial, an on-board screen, a metal strip trim, and the like. These components with retroreflective properties exert their respective beneficial effects and may also have some negative effects. For example, if the arrangement of these components having light reflecting properties in a vehicle is not reasonable, a corresponding projection may be formed on the glass surface of the front windshield or the side windshield. In this way, the projection formed on the glass surface may affect the driver's field of view, thereby creating a safety hazard.
Taking a part with a light reflection attribute as a vehicle-mounted screen and a glass surface as a glass surface of a vehicle window as an example, in order to avoid potential safety hazards caused by a projection area formed by the vehicle-mounted screen on the glass surface, in the process of developing a vehicle, simulation software is generally utilized, a projection area formed by the projection equipment on the projection equipment is analyzed based on projection equipment corresponding to the vehicle-mounted screen in the simulation software and shadow bearing equipment corresponding to the glass surface in the simulation software, and the arrangement position of the projection equipment is optimized based on an analysis result of the simulation software.
However, the current method for determining the projection area is complex, and the projection area cannot be determined quickly and efficiently. For example, currently, vehicle design engineers often use CAITA software to perform vehicle design, but CAITA software has no projection checking function, so each time projection checking is performed, a vehicle model designed by CAITA software is imported into UG, RAMSSIS, CAVA, OPTIS software for projection checking.
However, due to factors such as data format and software version, projection equipment, image bearing equipment and the like designed by CAITA software need to be subjected to format conversion and then imported into UG and other software for projection checking. The projection equipment, the shadow bearing equipment and the like after the format conversion are embodied in the UG and other software in a parameter eliminating mode, so that if the arrangement scheme of the projection equipment is unreasonable through the UG and other software, the arrangement parameters of the projection equipment cannot be directly adjusted in the UG and other software, the arrangement parameters of the projection equipment also need to be adjusted again on CAITA software, and the projection equipment is imported into the UG and other software for checking after adjustment. Thus, at least two design software is required to complete projection verification.
Therefore, when projection checking is performed on the vehicle scheme designed by CAITA software, a plurality of design software needs to be repeatedly used, and the operation is complicated, time-consuming and low in efficiency.
In order to solve the problems that a plurality of design software are needed to be repeatedly used when projection checking is carried out on a vehicle scheme designed by CAITA software, the operation is complicated, time is consumed and the efficiency is low, the invention discloses a method and a device for determining a projection area and electronic equipment.
The method for determining the projection area can carry out projection checking based on the vehicle scheme designed by CAITA software, can carry out optimization and projection checking synchronously based on the CAITA software implementation scheme, and does not need to repeatedly use a plurality of design software to carry out projection checking.
For example, a projection verification template may be created based on CAITA software, where the projection verification template is used to perform the method for determining a projection area disclosed in the present invention, so that the designed on-board screen may be mapped into CAITA software, and the projection device is obtained in CAITA software. Correspondingly, the designed glass surface can be mapped into CAITA software, and the shadow bearing device is obtained in CAITA software. Then, the projection checking template in CAITA software can be directly utilized to determine whether the arrangement position of the projection equipment is proper or not, and a plurality of design software is not required to be repeatedly used, so that the projection checking flow can be simplified, and whether the arrangement position of the projection equipment is proper or not can be quickly and efficiently determined and checked.
It should be noted that, the method for determining the projection area disclosed by the embodiment of the invention is not only applicable to CAITA software, but also applicable to UG, RAMSSIS, CAVA, OPTIS software, and the like, and the method for determining the projection area disclosed by the embodiment of the invention has the advantages of small calculated amount, accurate determined projection area, and the like.
The method for determining the projection area disclosed in the embodiment of the present invention is described below as an example.
Fig. 1 shows a flowchart of a method for determining a projection area according to an embodiment of the present invention, where the method is performed by an electronic device. As shown in fig. 1, the method comprises the steps of:
step 110, obtaining first simulation data of the projection device, second simulation data of the shadow bearing device and third simulation data of the eye point of the user.
Firstly, it should be noted that, in the following description of the embodiments of the present invention, the projection device, the image bearing device and the user's eyepoint all refer to the corresponding objects in the simulation software (such as CAITA, UG, RAMSSIS, CAVA, OPTIS).
The projection device in the embodiment of the invention may be any component which has a reflective property and may form a projection on the image bearing device, for example, the projection device may correspond to an instrument panel, a vehicle-mounted screen, a metal strip interior, and the like.
The first analog data may include position information, angle information, size information, etc. of the projection device. For example, the projection device corresponds to an in-vehicle screen, and the corresponding first analog data may include position information, angle information, size information, and the like, which correspond to the in-vehicle screen.
By a shadow-bearing device is meant a device that carries the projection, which may be, for example, a front windshield or a side windshield corresponding to the vehicle.
The second simulation data may include position information of a window frame of the simulation vehicle, position information of a glass surface of the window, size information of the glass surface of the window, curvature of the glass surface of the window, and the like.
The user eyepoint is used in the present invention to characterize the position of the user's (e.g., driver) eyes within a simulated vehicle. The user eyepoint includes a first eyepoint corresponding to a left eye of the user and a second eyepoint corresponding to a right eye of the user, for example.
The invention can take the first eye point simulation data of the first eye point and/or the second eye point simulation data of the second eye point as the third simulation data. For example, first eye point simulation data of a first eye point and second eye point simulation data of a second eye point may be acquired first, and then, the first eye point simulation data or the second eye point simulation data is used as third simulation data, or both the first eye point simulation data and the second eye point simulation data are used as third simulation data.
The present invention may also determine third simulation data based on the first eyepoint simulation data of the first eyepoint and the second eyepoint simulation data of the second eyepoint. For example, first eye point simulation data of a first eye point and second eye point simulation data of a second eye point may be acquired first, and then third simulation data may be determined based on the first eye point simulation data and the second eye point simulation data. For example, a center point between the first eye point and the second eye point may be determined based on the first eye point simulation data and the second eye point simulation data, and finally, the center point is taken as the third simulation data.
The calculation method for the user's eye point may be different among different vehicle design requirement standards, and the present invention may calculate the user's eye point according to any existing standard. For example, the user's eye point in the vehicle may be calculated based on ergonomically arranged hard points of the human body and the SAE 941 standard.
The first analog data of the projection device, the second analog data of the shadow bearing device, and the third analog data of the eye point of the user may be input by the user (e.g., a vehicle design engineer), or may be obtained from a server or a local memory, which is not limited in the present invention. The server or the local memory may store the first analog data of the projection device, the second analog data of the image bearing device, and the third analog data of the eye point of the user.
Wherein the first analog data includes analog point data for a plurality of projection points on the projection device. The method for determining the projection point is not limited in the present invention.
The projection points may be, for example, points on the outline of the projection device. Wherein the outline of the projection device refers to the outer edge line of the projection device. For example, the projection device corresponds to a rectangular vehicle-mounted screen, and the outline corresponding to the vehicle-mounted screen is a rectangular frame. For another example, the projection device corresponds to a circular instrument panel, and the outline corresponding to the circular instrument panel is a circular frame.
In this way, the contour of the projection device may be extracted based on the first simulation data of the projection device, and then a plurality of projection points may be further selected on the contour of the projection device. The invention is not limited to the selection of a plurality of projections on the outline of the projection device. For example, a plurality of projection points may be selected at equal intervals on the contour of the projection device, such that any two adjacent projection points in the plurality of projection points are equally spaced on the contour of the projection device.
In addition, after the outline of the projection device is extracted, the extracted outline of the projection device may be displayed on the display interface. The location of each proxel may also be identified on the display interface.
The invention is not limited to a specific implementation of extracting the contour of the projection device. For example, the native extraction function of the simulation software may be invoked to extract the contour of the projection device. For another example, it is also possible to separately design a contour extraction function and then extract the contour of the projection apparatus using the contour extraction function.
Because the projection area corresponding to the outline of the projection equipment can reflect the maximum projection area of the projection equipment on the shadow bearing equipment, the projection area of the projection equipment on the shadow bearing equipment can be determined based on the outline of the projection equipment. Further, the invention determines the projection area of the projection device on the shadow bearing device based on a plurality of projection points on the outline of the projection device, thus reducing the calculation amount for determining the projection area.
Step 120, based on the simulation point data, the second simulation data and the third simulation data, a projection line on the shadow bearing device is established.
First, the present invention can extract the configuration of the image bearing apparatus based on the second analog data.
Taking the example that the shadow bearing device corresponds to the front windshield, the front windshield comprises two sides, wherein one side is positioned on the inner side of the vehicle, and the other side is positioned on the outer side of the vehicle. Since the in-vehicle projection device forms a projection on a glass surface located on the vehicle inside, the glass surface in the embodiment of the invention refers to a glass surface located on the vehicle inside in the window.
After the glass surface of the front windshield is extracted, a structural diagram of the extracted glass surface, such as a three-dimensional diagram or a two-dimensional diagram, may be displayed on the display interface. For example, based on CAITA software, when step 120 is performed, a three-dimensional map of the glass surface may be displayed on a display interface in the working environment of CAITA software. For another example, based on the UG software, when step 120 is performed, a three-dimensional map of the glass surface may be displayed on a display interface in the working environment of the UG software.
The specific implementation of the extraction of the glass surface of the front windshield is not limited in the present invention. For example, the simulation software may be invoked to extract the glass surface of the front windshield. For another example, a single glass surface extraction function may be designed, and then the glass surface of the front windshield may be extracted using the glass surface extraction function.
Then, the first connection line may be established based on the analog point data and the third analog data.
Finally, a projection line on the shadow bearing device is established based on the first connection line and the second simulation data.
Fig. 2 is a schematic diagram of a method for creating projection lines on a shadow mask according to an embodiment of the present invention. The simulation software interface shown in fig. 2 includes a shadow bearing apparatus 10, a projection apparatus 20, an in-vehicle user 30, and a user eye point 31.
As shown in fig. 2, an example is given of determining the reflection point of the first projection point 21 on the contour of the projection device 20. First, a first connection line L 1 between the user's eyepoint 31 and the projection point 21 is constructed based on the simulation point data and the third simulation data, and then, the first connection line L 1 is projected on the shadow bearing apparatus 10, resulting in a projection line L Throwing in of the first connection line L1 on the shadow bearing apparatus 10.
It should be noted that, if there is a projection line l Throwing in corresponding to the first connection line l 1 on the image bearing apparatus 10, it indicates that there may be a reflection point corresponding to the projection point 21 on the projection line l Throwing in , so that the following step 130 may be further performed to determine the reflection point of the projection point 21 on the projection line l Throwing in . If the projection line l Throwing in corresponding to the first connection line l 1 does not exist on the projection device 10, it is stated that the projection point 21 does not form a reflection point on the projection device 10, so that the step of determining the reflection point of the projection point 21 on the projection device 10 ends in this way.
And 130, determining the reflection point of the projection point based on the projection line.
At present, in the process of performing back-image checking based on software such as UG, RAMSSIS, CAVA, OPTIS, a method for determining a back-image point of a projection point on a shadow bearing device 10 generally finds a back-image point corresponding to the projection point on the whole shadow bearing device, so that the calculated amount is large, and the found back-image point is not necessarily accurate.
In the embodiment of the present invention, the range of the reflection point of the projection point 21 is first reduced to be located on the projection line l Throwing in on the image bearing device 10, and then the reflection point of the projection point 21 on the projection line l Throwing in is determined based on the projection line l Throwing in , the projection point 21 and the user's eye point 31. In this way, compared to the scheme of directly finding the back-image point corresponding to the projection point 21 on the image bearing apparatus 10, the present invention can reduce the calculation amount of determining the back-image point and promote the accuracy of determining the back-image point.
In one implementation, determining the back-image point of the proxel 21 based on the projection line l Throwing in may be accomplished by continuing to refer to FIG. 2, where an alternate back-image point 40 may be selected on the projection line l Throwing in , the alternate back-image point 40 being any point on the projection line l Throwing in . Then, based on the alternate reflection point 40 and the analog point data, a second connection line l 2 is established, so that the connection between the alternate reflection point 40 and the projection point 21 is obtained. And then, based on the alternative reflection point 40 and the third simulation data, establishing a third connecting line l 3, so as to obtain a connecting line between the alternative reflection point 40 and the eye point 31 of the user. Next, based on the second connecting line l 2 and the third connecting line l 3, an incident angle α and a reflection angle β corresponding to the reflection point 40 are determined, where the incident angle α is an angle between the second connecting line l 2 and the normal l Method of , and the reflection angle β is an angle between the third connecting line l 3 and the normal l Method of . Wherein the normal l Method of passes through the alternative reflection point 40 and is perpendicular to the lithographic apparatus 10. Finally, in the case where the incident angle α corresponding to the alternate reflection point 40 is the same as the reflection angle β, the alternate reflection point 40 is determined as the reflection point of the projection point 21 on the projection line l Throwing in .
That is, the present invention traverses the alternative reflection points 40 on the projection line l Throwing in , finds the alternative reflection points 40 satisfying the equal magnitudes of the incident angle α and the reflection angle β, and determines the alternative reflection points 40 satisfying the equal magnitudes of the incident angle α and the reflection angle β as the reflection points of the projection points 21 on the projection line l Throwing in .
It should be noted that if the incident angles α and the reflection angles β corresponding to all the alternative reflection points 40 on the projection line l Throwing in are not equal, it is determined that the reflection point 21 does not exist on the image bearing apparatus 10.
After determining the corresponding back-image point of the first projection point 21, the above-mentioned step 130 is repeated to determine the back-image point corresponding to each remaining projection point on the contour of the projection device 20 one by one. In this way, a reflection point corresponding to each projection point on the contour of the projection apparatus 20 is obtained.
And 140, determining a projection area based on the reflection points of all the projection points.
Taking the projection device corresponding to the vehicle-mounted screen as an example, after the back-image point corresponding to each projection point on the outline of the projection device 20 is obtained, the area surrounded by the back-image points after being sequentially connected is determined as the projection area of the projection device 20 on the shadow bearing device 10.
It should be noted that if the third simulation data is first eye point simulation data of the first eye point or second eye point simulation data of the second eye point, or the third simulation data is data according to the first eye point simulation data and the second eye point simulation data, the projection area may be determined according to the method provided in the above embodiment. That is, if the third analog data corresponds to an eye position, each of the plurality of projection points corresponds to a back-image point, so that the back-image point of each of the plurality of projection points can define an area, i.e., a projection area of the projection apparatus.
If the third simulation data includes first and second eye point simulation data, then when determining the projection area of the projection device, the first and second eye point simulation data may be used as the third simulation data, respectively, to sequentially determine the corresponding first and second projection areas, and then, based on the first and second projection areas, the projection area is determined.
For example, a first projection line on the projection device may be established based on the simulated point data, the second simulated data, and the first eye point simulated data, then a first reflection point of the projection points is determined based on the first projection line, and then a first projection area is determined based on the first reflection points of all the projection points. And then, based on the simulation point data, the second simulation data and the second eyepoint simulation data, establishing a second projection line on the shadow bearing equipment, then, based on the second projection line, determining a second reflection point of the projection points, and then, based on the second reflection points of all the projection points, determining a second projection area. Finally, the union of the first projection area and the second projection area is determined as the projection area.
Wherein, the step of establishing the first projection line and the second projection line can be referred to the description of the step 120, the step of determining the first back-image point and the second back-image point can be referred to the description of the step 130, and the step of determining the first sub-projection area and the second sub-projection area can be referred to the description of the step 140. The above is not described here.
In order to check whether the arrangement position of the projection device is proper, after the projection area of the projection device is determined, the method further comprises the steps of firstly acquiring a safe visual field area on the shadow bearing device and then determining whether the arrangement position of the projection device is proper based on the safe visual field area and the projection area.
The safe visual field area may be a safe visual field area calculated according to a related standard. For example, the safe vision area corresponding to the glass surface 10 in the vehicle can be calculated according to the front vision requirement of the automobile driver and the national standard GB11532-2014 of the measuring method.
In one implementation, determining whether the placement of the projection device is appropriate based on the safe field of view region and the projection region may be accomplished by first determining whether there is an overlap region between the safe field of view region and the projection region. If there is an overlap region, it is further determined whether the overlap region is greater than a preset area threshold. If the overlapping area is greater than the preset area threshold, determining that the arrangement position of the projection device is not suitable, and readjusting the first analog data of the projection device is needed. If there is no overlapping area or the overlapping area is less than or equal to the preset area threshold, the arrangement position of the projection device is determined to be suitable, and the first analog data of the projection device does not need to be readjusted.
Further, after the first analog data of the projection device is adjusted, the adjusted first analog data of the projection device may be re-acquired, and the projection area may be re-determined based on the adjusted first analog data of the projection device.
For example, a projection verification template may be created based on CAITA software, which is used to perform the steps described above for determining the projection area and determining whether the placement location of the projection device is appropriate. After triggering the projection checking template, an input window can be displayed on a display interface under the working environment of CAITA software, and a user can input first simulation data of the adjusted projection device through the input window. The projection verification template then calculates a projection area based on the input first simulation data of the adjusted projection device and determines whether the arrangement position of the projection device is appropriate. Therefore, when the arrangement position of the projection equipment is inappropriate, the first simulation data of the projection equipment can be directly adjusted in CAITA software, then, the first simulation data of the adjusted projection equipment is continuously input again in the working environment of CAITA software, whether the arrangement position of the adjusted projection equipment is appropriate or not is checked again, and checking is repeated until the arrangement position of the projection equipment is appropriate. In this way, scheme optimization and projection verification can be synchronously performed in CAITA software, and projection verification is not required to be performed by repeatedly using a plurality of design software.
Accordingly, the check result may be displayed on a display interface in the working environment of CAITA software, where the check result may be displayed graphically and/or textually. For example, the safe view area, the projection area, and the overlapping area of the safe view area and the projection area are displayed on the display interface, and the area value of the overlapping area is displayed on the overlapping area of the safe view area and the projection area. Thus, the user can intuitively receive the projection checking result.
It should be noted that the foregoing embodiments are only described by way of example in which the shadow bearing apparatus 10 corresponds to a glass surface of a front windshield, and are not meant to limit the shadow bearing apparatus 10, and for example, the shadow bearing apparatus 10 may correspond to a glass surface of a side windshield. When the image bearing apparatus 10 corresponds to the glass surface of the side windshield, the corresponding projection area can be determined as well using the method provided by the above-described embodiment.
In summary, the method for determining the projection area provided by the embodiment of the invention has the advantages that firstly, whether the arrangement position of the projection equipment is proper or not can be checked under the working environment of simulation software (such as CAITA software), so that the synchronous implementation of the optimization of the arrangement scheme and the projection check of the projection equipment can be realized, the projection check is not required to be carried out by repeatedly using a plurality of design software, the projection check flow can be simplified, and whether the arrangement position of the projection equipment is proper or not can be quickly and efficiently determined. Secondly, when determining the back-image point of the projection point, the invention firstly reduces the range of the back-image point of the projection point to a projection line positioned on the image bearing device, and then determines the back-image point of the projection point on the projection line based on the projection line, the projection point and the user eye point. In this way, compared with the scheme of directly finding the reflection point corresponding to the projection point on the image bearing device, the method and the device can reduce the calculation amount of determining the reflection point and improve the accuracy of determining the reflection point. In addition, the method for determining the projection area provided by the embodiment of the invention is also suitable for UG, RAMSSIS, CAVA, OPTIS and other software, and the projection area is determined by adopting the method provided by the embodiment of the invention under the working environment of UG, RAMSSIS, CAVA, OPTIS and other simulation software, so that the calculated amount can be reduced, and the accuracy of the determined reflection point can be improved.
