Detailed ways

Hereinafter, exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited by the example embodiments described herein.

FIG. 1 is a schematic flowchart of a VR technology-based security prompt method provided by an exemplary embodiment of the present application. As shown in Figure 1, the safety prompt methods based on VR technology include:

Step 110: Acquire a pupil image of the user.

The pupil image of the user can be obtained through the interactive host, and the interactive host can be provided with a display and a camera. The camera can take an image of the user's pupil. The camera can also be a left and right camera. The left and right cameras are used to capture the user's pupil images to obtain the left image and the right image, and the left image is selected for image processing or the right image is selected for image processing to obtain the user's pupil image.

Step 120: Determine a virtual scene according to the pupil image.

Image processing is performed on the pupil image to obtain a new pupil image, and the virtual scene is determined according to the position or coordinate point of the pupil in the pupil image. For example, it is detected that the user's pupil is at the far left or close to the left hand direction, then correspondingly the indoor virtual scene can be acquired. It is detected that the user's pupil is at the far right or close to the right hand direction, then the outdoor virtual scene can be obtained accordingly.

Step 130: Respond to the operation instruction input by the user in the virtual scene.

The user inputs an operation instruction in the virtual scene through an interactive device, and the operation instruction may be a walking instruction, an instruction to rotate in a target direction, etc., wherein the interactive device may be a keyboard, a mouse, a handle, and the like. Through the user's operation on the interactive device, the operation instruction is generated and input into the virtual scene. In response to the operation instruction, the display device of the interactive device displays the corresponding action.

Step 140: Determine the target position corresponding to the operation instruction from the preset library.

A preset library can be set to store multiple target positions and operation instructions corresponding to multiple positions. For example, a preset number of keys can be set on the keyboard, and each key corresponds to a target position. If the operation of pressing the R key is obtained command, the position of the electrical cabinet corresponding to the operation command in which the R button is pressed can be determined from the preset library, and the electrical cabinet is displayed on the display device of the interactive host.

Step 150: Invoke the controllable virtual device corresponding to the target location.

Each target position can correspond to a virtual device or a virtual object, then the controllable virtual device corresponding to the target position can be selected. The controllable virtual device can be the wire connection in the virtual device, the faulty wire is removed, and the faulty main transformer is repaired. equipment installation, etc. The operation flow corresponding to the virtual device can be retrieved, and the first operation flow in the operation flow is displayed. After the user operation of the first operation flow is successful, the second operation flow in the operation flow is displayed. It should be understood that the target position may be a target point on the road in the virtual scene, and is not limited to the target position corresponding to the device.

Step 160: If the virtual device is triggered and not operated within the preset time period, generate prompt information to prompt the user to perform corresponding operations according to the prompt information.

If the virtual device is triggered within the preset time period and does not operate according to the target process (target operation process), prompt information is generated to prompt the user to perform corresponding operations according to the prompt information. For example, the user triggers the virtual device (helmet), but does not put on the helmet after 3 minutes, so a prompt message is generated to prompt the user to put on the helmet. The instruction to put on the helmet can be operated by the user through the keyboard, mouse, handle etc. to generate. For another example, if the user grabs the dual-control harness-type seat belt by hand, if it is not operated, the user will be reminded to hold the dual-control harness-type seat belt. For another example, stand on the cross arm of the transformer and connect the ground wire to the low-voltage side of the high-voltage side. The seat belt hook should be hung on the cross-arm (if the hook is not hung on the cross-arm, the employee will feel a high fall at this time, and the sound of falling will remind you that you have violated the safety regulations at this time, please be sure to promptly Hang the hook on the crossbar before continuing). Remove the transformer, open the low-voltage side knife switch of the transformer, remove the old transformer from the lead, and replace the secondary metering wire (simulate a strong wind at this time, so that the employee feels a high fall, and a voice reminds you to replace the metering device in the table area. Pay attention to weather changes to avoid danger). Place the text of safety measures for dangerous points, and remind to sign and confirm through the user interface. The prompt information can also have a voice prompt function, which can prompt the user by voice, and the voice prompt includes wrong operation, next operation, stop operation, etc.

A safety prompting method based on VR technology provided by the present application, the method includes: acquiring a pupil image of a user, determining a virtual scene according to the pupil image, responding to an operation instruction input by the user in the virtual scene, and determining from a preset library The target position corresponding to the operation instruction is called, the controllable virtual device corresponding to the target position is called, and if the virtual device is triggered and not operated within a preset time period, a prompt message is generated to prompt the user to perform corresponding actions according to the prompt message. operate. Through the operation instruction input by the user in the virtual scene, the first target position corresponding to the operation instruction is determined, and then the controllable virtual equipment is called, so that the operator can control the virtual equipment in the virtual scene. When the virtual scene is mis-operated or has not been operated for a long time, the correct operation process can be appropriately provided.

FIG. 2 is a schematic flowchart of a safety prompt method based on VR technology provided by another exemplary embodiment of the present application. As shown in FIG. 2, step 120 may include:

Step 121: Determine the pupil position in the pupil image.

Multiple coordinates corresponding to the pupil position can be determined by establishing a coordinate system, selecting multiple edge points for the pupil position in the pupil image, and determining the coordinate system of the multiple edge points.

Step 122: Determine the virtual scene according to the pupil position.

A coordinate interval can be set to verify whether the coordinate systems of the multiple edge points are all within the coordinate interval, or the number of the coordinate systems of the multiple edge points in the coordinate interval is greater than or equal to the first preset number threshold. For example, if there are 5 edge points, but 4 are in the coordinate interval, it is determined that the pupil position is in the coordinate interval. The coordinate interval may correspond to a virtual scene, and if there are multiple coordinate intervals, it corresponds to multiple virtual scenes.

FIG. 3 is a schematic flowchart of a safety prompt method based on VR technology provided by another exemplary embodiment of the present application. As shown in FIG. 3, step 122 may include:

Step 1221: Obtain the center coordinates corresponding to the pupil position.

The pupil image is divided so that the pupil image is divided into multiple images of equal area, that is, the pupil image is divided by horizontal lines, vertical lines and lines in other directions, and the intersection of the final lines is the center coordinate corresponding to the pupil position.

Step 1222: Determine the virtual scene according to the center coordinates and the preset coordinate interval.

A preset coordinate interval is set, and when the center coordinates are within the preset coordinate interval, the corresponding virtual scene can be determined.

In one embodiment, the preset coordinate interval is a first preset coordinate interval and a second preset coordinate interval, and the direction of the first preset coordinate interval and the direction of the second preset coordinate interval are opposite coordinate directions, step 1222 It can be specifically implemented as follows: if the center coordinates are within the first preset coordinate interval, a first virtual scene is displayed, wherein the first virtual scene is a virtual indoor scene, and if the center coordinates are within the second preset coordinate interval, then A second virtual scene is displayed, wherein the second virtual scene is a virtual outdoor scene.

If the center coordinates are within the first preset coordinate range, a first virtual scene is displayed, wherein the first virtual scene is a virtual indoor scene. If the center coordinates are within the second preset coordinate interval, a second virtual scene is displayed, wherein the second virtual scene is a virtual outdoor scene.

FIG. 4 is a schematic flowchart of a safety prompt method based on VR technology provided by another exemplary embodiment of the present application. The virtual device includes a line device, and step 150 may include:

Step 151: Invoke a controllable virtual device corresponding to the target position, wherein the target position includes a prompt symbol, and the prompt symbol points to the virtual device.

Because there may be multiple virtual devices retrieved, a prompt symbol can be displayed when displaying a virtual device, and the prompt symbol points to the virtual device, so that the user can determine the target virtual device, that is, the viewed virtual device. If the retrieved virtual device is one, the user can intuitively determine the target virtual device.

FIG. 5 is a schematic flowchart of a safety prompt method based on VR technology provided by another exemplary embodiment of the present application. As shown in Figure 5, the safety prompt method based on VR technology may further include:

Step 170: If an instruction that the virtual device is operated incorrectly is received, generate feedback information.

If an instruction is received that the virtual device is operated incorrectly, that is, the operation is not performed according to the operation prompt in the target process, feedback information is generated, and the feedback information includes a vibration instruction. For example, the operation prompt should be connected to the insulating sheet first, and then the wire, and the user directly connects the wire, that is, does not follow the operation prompt in the target process, then a feedback message will be generated with a vibration command to remind the user of the error operate.

Step 180: Send the feedback information to the interactive device to make the interactive device vibrate, wherein the interactive device is a device directly operated by the user.

The vibration instruction carried by the feedback information is sent to the interactive device to cause the interactive device to vibrate, so that the user knows that the operation just now is a wrong operation. For example, in the inspection of the electric energy meter of the VR substation, in the process of string current and voltage, the short circuit should be connected first. If the short circuit is not connected first but other operations are performed, the handle will feedback the vibration of electric shock.

FIG. 6 is a schematic flowchart of a safety prompt method based on VR technology provided by another exemplary embodiment of the present application. As shown in FIG. 6, after step 180, the safety prompting method based on VR technology may further include:

Step 190: If the hazard level corresponding to the wrong operation of the virtual device is greater than or equal to the preset hazard level threshold, a simulation animation is generated to display the hazard scene caused by the wrong operation of the virtual device.

If the hazard level corresponding to the wrong operation of the virtual device is greater than or equal to the preset hazard level threshold, a simulation animation will be generated, and the simulation animation will simulate the occurrence of the real situation, so that the user can intuitively see the serious damage caused by the wrong operation. harm. The hazard level can be set to 3 levels, which are high, medium and low. A medium level indicates a moderate degree of hazard, which is likely to cause equipment damage, while a low level indicates a lower degree of hazard and less damage to the equipment.

In addition, if the virtual device has been operated according to the preset operation process, a score interface is generated.

The score interface displays the number of user's wrong operations, and the severity level of the user's wrong operation, which is helpful for users to intuitively know their own shortcomings. If the virtual device has completed the operation according to the preset operation process, the video animation during the operation is stored, and the video animation is stored in the video library. The user can download the video animation to the mobile phone or other mobile devices and watch it anytime, anywhere. Video animation.

After the score interface is generated, if an instruction from the user to freely observe the virtual scene is received, the user can freely observe and operate the virtual scene without following the preset process, so that the user can freely operate any device in the virtual scene, and The user is no longer prompted, just an animation of the action is generated. If the user has a wrong operation in the free operation, the operation animation will also display the harm caused by the operation, so that the user can more intuitively see the running state of each device and how to operate the device correctly.
