As shown in fig. 3, in a usage scenario of the touch sensitivity self-inspection method of the present invention, an infrared camera module (4), a projector module (5) and an RGB camera module (6) are disposed at a projector and camera module installation location (1) of a desktop projector. In addition, the desktop projector is also provided with an LCD display screen (2) on the vertical wall below the projector module (5), and a laser module (3) at the bottom of the vertical wall. Therefore, the laser module (3) of the desktop projector projects laser to the projection area (8) on the desktop, the laser emitted by the laser module (3) can form a plane, and the range of the plane is overlapped with the projection area (8). When a user clicks on the desktop through a finger, the laser is reflected by the fingertip part to form a light spot which can be captured only by the infrared camera.

At the moment, the main board (7) analyzes that a light spot exists in the image, gives a light spot coordinate, finds the same coordinate point of the projection content, makes a corresponding response (such as clicking a button, drawing a line and the like), and shows the same coordinate point in a new frame of projection.

Referring to fig. 2, fig. 2 is a flowchart illustrating a touch sensitivity self-testing method according to a first embodiment of the present invention. In a first embodiment of the touch sensitivity self-inspection method of the present invention, the touch sensitivity self-inspection method of the present invention includes:

step S10: when a projector self-checking instruction is detected, projecting a projection image consisting of a plurality of squares to a projection area, wherein the color of each square is a first color;

in this embodiment, when the desktop projector detects a projector self-checking instruction, the desktop projector projects a projection image composed of a plurality of squares into the projection area through its own projection module, and at this time, the colors of the squares are all the first color.

It should be noted that, in this embodiment, the desktop projector body may detect a projector self-check instruction triggered by a user when the user starts a self-check function preset by the user, or the desktop projector body may further automatically trigger the projector self-check instruction according to a preset time period. It should be understood that, based on different design requirements of practical applications, in different possible embodiments, the desktop projector may set different time periods, and the touch sensitivity self-detection method of the present invention is not limited to a specific size of the time period.

It should be noted that thedesktop projector projects 10 × 8 squares to the projection area through its own projection module, it should be understood that, based on different design requirements of practical applications, in different feasible embodiments, the desktop projector may certainly set different matrix squares, and the touch sensitivity self-checking method of the present invention is not limited to the specific size of the matrix square. In addition, at this time, the color of the square is the first color, it should be understood that, based on different design requirements of practical applications, in different feasible real-time manners, the desktop projector may certainly set different colors as the first color, and the touch sensitivity self-checking method of the present invention is not limited to this color.

Step S20, acquiring image data of the projection area through the infrared camera module, and converting the color of a target square into a second color when a light spot appears in the target square in each square is detected according to the image data, wherein the light spot is generated by performing interactive operation on the target square when the laser module emits laser to the projection area;

in this embodiment, after thedesktop projector projects 10 × 8 squares of a first color onto a projection area through its own projection module, the desktop projector further emits laser light onto the projection area through its own laser module, guides a user to click each square with a finger or other interactive tool, acquires image data of the projection area through its own infrared camera module, and finds a target square where a light spot is located and converts the color of the target square into a second color if the light spot reflected by a fingertip or other tool when the user performs an interactive operation is detected to appear in the image data.

In addition, in this embodiment, the user follows the guidance of the desktop projector to perform a click operation on each red grid, and at the same time, the infrared camera module continuously acquires image data of the projection area and returns the image data to the main board for processing. When the light spot appears in the image data, the mainboard analyzes the light spot coordinate, so that a target square where the light spot is located is found, and a corresponding response is made, namely, the color of the target square is changed from red to green.

It should be noted that the color of the grid where the light spot appears is converted into the second color, it should be understood that, based on different design requirements of practical applications, the desktop projector may certainly set a different color as the second color in different feasible real-time manners, and the touch sensitivity self-checking method of the present invention is not limited to this color.

And step S30, when the self-checking ending instruction of the projector is detected, detecting whether the color of each square is converted into the second color so as to obtain a detection result of the sensitivity of the projection area.

In this embodiment, when the desktop projector detects a self-checking end instruction of the projector, it detects whether the colors of all the squares are converted into the second color, so as to obtain whether the sensitivity of the area where each square is located is normal, and further obtain the detection result of the sensitivity of the whole projection area.

Further, in a possible embodiment, in step S30, the step of detecting whether the color of each square is converted into the second color to obtain the detection result of the sensitivity of the projection area may include:

step 301, if it is detected that the color of each square is converted into the second color, obtaining a detection result of the sensitivity of the projection area as normal sensitivity;

in this embodiment, when the desktop projector detects the self-checking end command, if it detects that the color of each square is converted into the second color, it is determined that the sensitivity of the projection area is normal.

Illustratively, when the desktop projector detects a self-checking end instruction, if the color of each square is detected to be converted from red to green, the sensitivity of the projection area is determined to be normal.

Step 302, if it is detected that there is a square grid of the first color in each square grid, obtaining a detection result of the sensitivity to the projection area as a sensitivity reduction.

In this embodiment, when the desktop projector detects the self-checking end instruction, if it is detected that the color of each square still has a square of the first color, it is determined that the sensitivity of the square area still having the first color in the projection area is reduced.

For example, when the desktop projector detects a self-checking end instruction, if red squares still exist in the projection area, it is determined that the sensitivity of the area where the red squares still exist in the projection area is reduced.

In this embodiment, when the desktop projector detects the projector self-inspection instruction, the desktop projector projects a projection image composed of a plurality of squares into the projection area through its own projection module, where the colors of the squares are all the first color. After the desktop projector emits laser to the projection area through the laser module of the desktop projector, the desktop projector guides a user to click each square to execute interactive operation, image data of the projection area is obtained through the infrared camera module of the desktop projector, if light spots reflected by fingertips or other interactive tools when the user executes the clicking operation are detected to appear in the image data, a target square where the light spots are located is found, and the color of the target square is converted into a second color. When the desktop projector detects a self-checking finishing instruction of the projector, whether the colors of all the squares are converted into the second color or not is detected, so that whether the sensitivity of the area where each square is located is normal or not is obtained, and further, the detection result of the sensitivity of the whole projection area is obtained.

In this way, in the embodiment of the present invention, the projection module projects a projection image composed of a plurality of squares of a first color to the projection area, so as to guide the user to perform a click operation in each square after the laser module emits laser light to the projection area, so that, when a light spot reflected by a finger of the user is recognized in a certain square area, the color of the square is converted into a second color by the projection module, and further, a detection result of the sensitivity of the projection area can be obtained by detecting whether the color of each square is converted into the second color.

Further, based on the first embodiment of the touch sensitivity self-inspection method of the present invention, a second embodiment of the touch sensitivity self-inspection method of the present invention is provided.

In this embodiment, the desktop projector further includes a display screen, and after step 302, the touch sensitivity self-inspection method of the present invention may further include:

It should be noted that, in this embodiment, the Display screen included in the desktop projector may be an LCD (Liquid Crystal Display) screen or an LED (light emitting diode) Display screen. It should be understood that, based on different design requirements of practical applications, in different possible embodiments, the desktop projector may use any different kinds of display screens on the market, and the touch sensitivity self-checking method of the present invention is not limited to the specific kind of display screens used by the desktop projector.

In addition, in this embodiment, the processing performed on the laser module and/or the infrared camera module and/or the display screen includes, but is not limited to: cleaning, barrier/stickies removal and removal.

In this embodiment, the position of the square grid of the first color in the projection area is detected by the desktop projector, and if it is detected that the target area of the square grid of the first color in the projection area completely coincides with the projection area, it is determined that the sensitivity of the whole projection area is reduced, and a first prompt prompting a user to process the laser module and/or the infrared camera module and/or the display screen is displayed on the display screen.

Illustratively, the coordinates of the grids where no light spot is recognized in each grid memorized by the main board are detected to obtain the boundary coordinates of the area where all grids where no light spot appears, so as to obtain the position of the red grid in the projection area. When the cells of the projection area are all red, the user is prompted on the LCD screen to clean or remove the laser module, infrared camera module and/or LCD screen or directly remove the obscuration/stickers, as shown in fig. 5.

In addition, in this embodiment, after step 302, the touch sensitivity self-checking method of the present invention may further include:

In this embodiment, the position of the square grid with the first color in the projection area is detected by the desktop projector, and if the central part of the projection area of the target area of the square grid with the first color in the projection area is detected, it is determined that the sensitivity of the central part of the projection area is reduced, and a second prompt for prompting a user to process the laser module is displayed on the display screen.

Illustratively, the coordinates of the boundaries of the areas where all the squares without light spots appear are obtained by detecting the coordinates of the squares where no light spot is identified in the squares memorized by the main board, so as to obtain the positions of the red squares in the projection area. When the red square is in the center part of the projection area, the user is prompted to clean or remove the laser module or directly remove the laser module through the LCD screen, as shown in FIG. 6.

In addition, in this embodiment, the desktop projector further includes a display screen, and after step 302, the touch sensitivity self-checking method of the present invention may further include:

In this embodiment, the position of the square in the first color in the projection area is detected by the desktop projector, and if the edge part of the target area where the square in the first color is located in the projection area is detected, it is determined that the sensitivity of the edge part of the projection area is reduced, and a third prompt prompting the user to process the display screen is displayed on the display screen.

Illustratively, the coordinates of the grids where no light spot is recognized in each grid memorized by the main board are detected to obtain the boundary coordinates of the area where all grids where no light spot appears, so as to obtain the position of the red grid in the projection area. As shown in fig. 7, when the red squares are at the edge portion of the projection area, the user is prompted through the LCD screen to clean/remove stickies from the LCD screen.

In this embodiment, the touch sensitivity self-checking method of the invention detects the position of the grid of the first color in the projection area through the desktop projector, determines that the sensitivity of the whole projection area is reduced if it is detected that the target area of the grid of the first color in the projection area completely coincides with the projection area, and displays a first prompt prompting a user to process the laser module and/or the infrared camera module and/or the display screen on the display screen. And if the target area of the grid with the first color in the projection area is detected to be in the central part of the projection area, determining that the sensitivity of the central part of the projection area is reduced, and displaying a second prompt for reminding a user to process the laser module on the display screen. And if the edge part of the target area of the grid with the first color in the projection area is detected to be in the projection area, determining that the sensitivity of the edge part of the projection area is reduced, and displaying a third prompt for reminding a user to process the display screen on the display screen.

Therefore, the embodiment of the invention divides the processing of the projection area sensitivity abnormity of the desktop projector into three conditions, and displays the corresponding prompt on the display screen, so that the user can more clearly know the reason and the solution of the abnormity, and the user experience is improved when the laser bifurcation self-checking method of the desktop projector is adopted by the user.

Exemplarily, as shown in the flow of fig. 4, a corresponding prompt is given to the user through the detection result obtained by the first self-check, that is, if the detection result indicates that none of the squares in the entire projection area is recognized, the user is prompted to clean the infrared camera module, the laser module and/or the LCD screen or remove the occlusion; if the detection result indicates that the central part of the projection area is not recognized, prompting a user to clean the laser module; and if the detection result is that the central part of the projection area is not recognized, prompting the user to clean the LCD screen or remove the stickers. After the user executes corresponding operations, secondary self-checking is started, a projection module of the desktop projector projects 10 x 8 red squares to a projection area, the desktop projector guides the user to click each square after emitting laser to the projection area through a laser module, at the moment, the infrared camera module continuously acquires image data of the projection area and transmits the acquired image data to the mainboard, the mainboard analyzes whether a user finger reflects a light spot or not in the image data, and the red squares with the light spots identified are converted into green squares. And if the user finishes clicking all the squares according to the guidance of the desktop projector, finishing clicking, namely finishing the secondary self-checking. Finally, if all the squares can be recognized, that is, their colors are changed to green, it is determined that the sensitivity of the projection area is restored to normal, and the desktop projector can be normally used.
