The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.
The three-dimensional infrared imaging device for a home appliance and the home appliance according to the embodiments of the present invention will be described with reference to the accompanying drawings.
Fig. 1 is a block diagram of a three-dimensional infrared imaging apparatus for a home appliance according to an embodiment of the present invention.
In one embodiment of the present invention, the household electrical appliance may be an air conditioner, a washing device, a refrigeration device, a water heater, or other household electrical appliances. It should be noted that the three-dimensional infrared imaging apparatus for a home appliance of the present invention can be applied to three-dimensional image construction in a room at home, and can also be applied to three-dimensional image construction in a room at a mall, which is not limited herein.
As shown in fig. 1, the three-dimensional infrared imaging apparatus for home appliances of the present invention may include: the device comprises an infrared area array emitter 10, an infrared image acquisition part 20 and a controller 30.
The infrared area array emitter 10 is disposed on the household electrical appliance, and is configured to project infrared points into a space. The infrared image acquisition part 20 is arranged on the household appliance and is used for acquiring images of infrared points in space and acquiring image data. The controller 40 is connected to the infrared image capturing assembly 30 for analyzing and processing the image data to construct a three-dimensional image of the space.
In one embodiment of the present invention, the infrared area array emitter 10 may include at least one infrared emitting tube, the infrared emitting tube is a light emitting body composed of infrared light emitting diodes, and the light emitting devices directly convert electric energy into near infrared light (invisible light) and radiate out, and the light emitting devices are arranged according to a certain rule to form the infrared area array emitter 10. The number of the infrared transmitting tubes in the infrared area array transmitter 10 may be determined according to the size of the space, or may be determined according to the number of the infrared area array transmitters 10, for example, if a plurality of infrared area array transmitters 10 are arranged on the household electrical appliance device when the space area is fixed, the number of the infrared transmitting tubes in each infrared area array transmitter 10 may be less; if an infrared area array emitter 10 is installed on the household appliance, the number of infrared emission tubes in the infrared area array emitter 10 may be larger.
Specifically, when the household electrical appliance is powered on and works, optical triangulation is adopted, infrared points are regularly projected into a room according to the arranged positions by using infrared emission tubes in the infrared area array emitter 10, and the infrared image acquisition assembly 20 captures the infrared points in the room to acquire three-dimensional point cloud data of objects in the room. The infrared image acquisition component 20 sends the acquired three-dimensional point cloud data to a controller 40 (a three-dimensional imaging processor MCU (micro controller Unit)), which receives the three-dimensional point cloud data, analyzes and processes the point cloud data, and constructs a three-dimensional image of the room object. Among them, optical triangulation is one of the most common optical three-dimensional measurement techniques, and based on conventional triangulation, depth information of a point to be measured is calculated from an angle change caused by a deviation of the point relative to an optical reference line.
According to an embodiment of the present invention, as shown in fig. 2, the household electrical appliance may include a top cover 110, an outer circumferential wall of the top cover 110 being recessed radially inward to define a receiving groove, and the infrared area array emitter 10 and the infrared image capturing assembly 20 being disposed in the receiving groove.
Specifically, for example, the household electrical appliance is a cylindrical vertical air conditioner, a top cover 110 is arranged at the top of the vertical air conditioner, a groove (containing groove) is formed in the top cover 110 and used for containing the infrared area array emitter 10 and the infrared image acquisition assembly 20, wherein the size of the groove can be set according to actual conditions, for example, the size of the groove can be determined according to the number and size of the infrared area array emitters 10 and the size of the infrared image acquisition assembly 20, and the size of the groove is enough for containing the required infrared area array emitter 10 and the required image acquisition assembly 20. According to the utility model, the infrared area array emitter 10 and the image acquisition assembly 20 are arranged in a groove mode, so that on one hand, the integral appearance of the vertical air conditioner is attractive, and on the other hand, the vertical air conditioner can be ensured not to fall off when the infrared area array emitter 10 or the image acquisition assembly 20 is installed and loosened.
In another embodiment of the present invention, the peripheral wall of the lower edge of the top cover 110 protrudes radially outward by a fixed area for placing the infrared area array emitter 10 and the image pickup assembly 20. The size of the fixed area is also set according to the actual situation, and the same setting mode is adopted as the size of the groove, which is not described again here.
It should be noted that, in the above embodiment, when a cylindrical vertical air conditioner is taken as an example, the top cover 110 is generally circular, and similarly, when the air conditioner is in other shapes, the top cover 110 is adapted to the top of the air conditioner. When the air conditioner is a hanging air conditioner (hung on a wall), the position for arranging the infrared area array emitter 10 and the position for arranging the image acquisition assembly 20 can be defined directly on the top of the air conditioner.
According to one embodiment of the present invention, there may be two infrared area array emitters 10, and two infrared area array emitters 10 are correspondingly disposed on two sides of the infrared image capturing assembly 20 and are disposed in the containing groove along with the infrared image capturing assembly 20 in a radial direction.
With continued reference to fig. 2, taking two infrared area array emitters 10 as an example, by placing the infrared area array emitters 10 outward, a wider range of infrared projection points can be obtained, for example, by placing them against a groove. In order to improve the collection precision and the collection comprehensiveness of the infrared image collection assembly 20, the infrared image collection assembly 20 can be arranged in the middle of the groove, the two infrared area array emitters 10 are symmetrically arranged and are adjacent to the infrared image collection assembly 20, and the infrared image collection assembly 20 is also arranged outwards.
In addition, when the axial height of the top cover 110 is sufficient, two infrared area array emitters 10 can be arranged adjacently, and the infrared image capturing assembly 20 can be arranged above or below the infrared area array emitters 10 along the axial direction of the top cover 110, in other words, the arrangement positions of the infrared area array emitters 10 and the infrared image capturing assembly 20 can be adjusted according to actual conditions.
It should be noted that two infrared area array emitters 10 are provided in the above embodiment shown in fig. 2 only as an embodiment of the present invention, and one, three, four, etc. may also be provided, where the specific number is determined by actual circumstances. For example, when the room space is small, the infrared area array transmitter 10 may be disposed as one, and in this case, the infrared image capturing assembly 20 may be disposed on the left or right side of the infrared area array transmitter 10 in the radial direction of the top cover 110. When the room space is large and the number of the infrared area array emitters 10 can be three, the two infrared area array emitters 20 can be symmetrically arranged on the left side and the right side of the infrared image acquisition assembly 20, and the other one can be axially arranged above or below the infrared image acquisition assembly 20, so that accurate three-dimensional point cloud data of objects in the room can be acquired.
According to one embodiment of the present invention, the infrared image capturing assembly 20 is rotatably disposed within the holding tank to adjust the orientation of the image capturing end of the infrared image capturing assembly 20 in the circumferential and/or axial direction of the top cover 110.
According to one embodiment of the present invention, the infrared image capturing assembly 20 may include a rotating mount 21 and an infrared camera 22 disposed on the rotating mount.
Specifically, the infrared camera 22 can acquire the infrared light emitted by the infrared area-array emitter 10, but since the field of view of the infrared camera 22 is limited, in order to expand the shooting field of view, the rotating support 21 is arranged below the infrared camera 22 to drive the infrared camera 22 to rotate, so as to expand the shooting field of view of the infrared camera 22. For example, with the top cover 110 as a reference plane, the rotating support 21 may rotate left or right along the circumferential direction of the top cover 110, or may rotate upward or downward along the axial direction of the top cover 110, that is, the infrared camera 22 may capture a range of a half sphere, thereby realizing omnidirectional imaging in a room. The rotating device has a good effect on accurately tracking and positioning the movable object in the room, particularly on positioning movable sub-equipment in a primary-secondary system.
In one embodiment of the present invention, the rotation direction of the rotating support 21 can be controlled by a driving motor, and the controller 30 can drive the rotation direction of the rotating support 21 by controlling the rotation direction of the driving motor.
Further, in order to more fully acquire the point cloud data in the space, in one embodiment of the present invention, the top cover 110 may be rotated in a circumferential direction.
As shown in fig. 3, the top cover 110 can rotate along the circumferential direction, and when the top cover 110 rotates along the circumferential direction, the infrared area array emitter 10 and the infrared image capturing assembly 20 disposed in the groove of the top cover 110 also rotate along with the rotation of the top cover 110, so that the coverage area of the infrared point projected by the infrared area array emitter 10 in the space is wider, and the infrared image capturing assembly 20 can capture a wider range of infrared point images.
According to an embodiment of the present invention, as shown in fig. 4, the three-dimensional infrared imaging apparatus for a home appliance may further include: the first driving member 40, the first driving member 40 is connected to the controller 30, and drives the top cover 110 to rotate under the control of the controller 30. The first driving member 40 may be a driving motor.
Specifically, the cap top 110 may rotate clockwise or counterclockwise in the circumferential direction, and the specific rotation direction is determined by a control signal of the controller. For example, when the controller 40 outputs a high level signal, the current output to the first driving member 40 is a forward current, and then the first driving member 40 drives the top cover 110 to rotate clockwise along the circumferential direction; when the controller 40 outputs a low level signal, the current output to the first driving member 40 is a reverse current, and then the first driving member 40 drives the top cover 110 to rotate counterclockwise in the circumferential direction.
It should be noted that the angle of the first driving member 40 driving the top cover 110 to rotate along the circumferential direction can be set according to actual conditions, for example, the angle of the top cover 110 rotating along the circumferential direction can be less than or equal to 270 ° when the air conditioner is installed at a corner, and the angle of the top cover 110 rotating along the circumferential direction can be less than or equal to 180 ° when the air conditioner is installed on a wall.
