Head-mounted display devices containing optical waveguide lenses will be affected by the external lighting environment, generating various types of stray light and ghost images that can be observed by the human eye.

[0038] In some embodiments, the data processing unit of the head mounted display device is used to obtain the array position information of the target light source unit, and determine the spatial position information of the target light source unit relative to the head mounted display device according to the array position information. The data processing unit can accurately obtain the spatial position information of the target light source unit relative to the head mounted display device by calculating the array position information of the target light source unit. It can provide accurate detection light data for subsequent updating of the parameters of the head mounted display device.

[0039] It can be understood that by arranging multiple light source units in an equally spaced array in the light source device and controlling the target light source unit to irradiate the target light, the lighting illumination in most usage scenarios can be simulated, and the target light intensity of the target light can be accurately collected by the light intensity collection unit. The spatial position information of the target light source unit relative to the head-mounted display device can be accurately calculated based on the array position information of the target light source unit, which can provide accurate detection light data for subsequent updating of the parameters of the head-mounted display device, thereby greatly improving the display quality of the head-mounted display device to improve the user experience.

[0040] In some embodiments, Figure 2 As shown, the light source device includes a rectangular box 130, and two sides of the rectangular box 130 include a first side 131 and a second side 132, and a plurality of light source units 121 are arranged in an array at equal intervals on the inner surfaces of a top surface 133 and a bottom surface 134, and each light source unit 121 is provided with unique array position information.

[0041] In some embodiments, the bottom surface 134 is divided into a plurality of longitudinal columns by a plurality of longitudinal straight lines at a first preset spacing, and the bottom surface 134 is divided into a plurality of transverse rows by a plurality of transverse straight lines at a second preset spacing, and the intersection of each longitudinal straight line and transverse straight line is used as a light source setting point, and a light source unit is set in the light source setting point, and the longitudinal straight lines are sorted from left to right to obtain the position number of each longitudinal straight line, and the position number of each longitudinal straight line is used as the array horizontal coordinate of the light source unit; the transverse straight lines are sorted from the first end to the second end to obtain the position number of each transverse straight line, and the position number of each transverse straight line is used as the array vertical coordinate of the light source unit. The first preset spacing and the second preset spacing can be set according to actual conditions, and the embodiment of the present invention does not specifically limit this.

[0042] For example, Figure 3 As shown, Figure 3, which is a plan view of the bottom surface, the bottom surface is divided into a plurality of longitudinal columns by a plurality of longitudinal straight lines at a first preset interval, so as to obtain longitudinal columns 11, 12, 13 and 14; the bottom surface is divided into a plurality of transverse rows by a plurality of transverse straight lines at a second preset interval, so as to obtain transverse rows 21, 22, 23 and 24; the intersection of each longitudinal straight line and the transverse straight line is used as a light source setting point, and light source units a, b, c, d, e, f, g, h and i are set in the light source setting point, Figure 3 The X direction of the arrow is from left to right, and the Y direction of the arrow is from the first end to the second end; and the position number of each longitudinal straight line is used as the array horizontal coordinate of the light source unit, and the position number of each transverse straight line is used as the array vertical coordinate of the light source unit, so that the coordinates of light source unit a are (1,1), the coordinates of light source unit b are (1,2), the coordinates of light source unit c are (1,3), the coordinates of light source unit d are (2,1), the coordinates of light source unit e are (2,2), the coordinates of light source unit f are (2,3), the coordinates of light source unit g are (3,1), the coordinates of light source unit h are (3,2) and the coordinates of light source unit i are (3,3).

[0043] It should be noted that, similarly, the two side surfaces and the top surface of the rectangular box can be used to divide the positions of light source units and set the light source units. The specific division of the positions of light source units and the setting of light source units can refer to the method of setting the light source units on the bottom surface.

[0044] It should be noted that the light source unit may also be disposed at the junction of the first side surface, the top surface, the second side surface and the bottom surface of the rectangular box, as shown in FIG. Figure 2 It can be understood that the first side surface, the top surface, the second side surface and the bottom surface are all divided into horizontal rows at a second preset spacing, so that the horizontal straight lines where the surfaces meet are connected, and the connection points of the horizontal straight lines where the surfaces meet are used as the light source unit position points.

[0045] In some embodiments, the light source device determines the target light source unit from multiple light source units according to the target array position information carried in the light source control instruction. The target light source unit can be accurately determined from multiple light source units through the target array position information carried in the light source control instruction.

[0046] Exemplarily, the target array position information carried in the light source control instruction is the bottom surface and the coordinates are (1, 3), and the light source unit c on the bottom surface of the rectangular box is determined to be the target light source unit.

[0047] In some embodiments, the position information of the head mounted display device inside the rectangular box is obtained, and the spatial position information of the target light source unit relative to the head mounted display device is determined based on the position information and the array position information, wherein the spatial position information includes the azimuth and elevation angle of the target light source unit relative to the head mounted display device.

[0048] In some embodiments, the method for obtaining the position information of the head-mounted display device inside the rectangular box can be: a distance sensor is provided in the head-mounted display device, and the distance between the head-mounted display device and the first side surface, second side surface, bottom surface and top surface of the rectangular box is obtained through the distance sensor, and the position information of the head-mounted display device inside the rectangular box is determined based on the distance to the first side surface, second side surface, bottom surface and top surface of the rectangular box.

[0049] In some embodiments, the head-mounted display device is projected onto one side of the rectangular box surface where the target light source unit is located to obtain a target projection point; the azimuth angle of the target light source unit relative to the head-mounted display device is determined based on the position of the target projection point and the array position information; the pitch angle of the target light source unit relative to the head-mounted display device is determined based on the position of the target projection point and the array position information.

[0050] In some embodiments, the method for determining the azimuth angle of the target light source unit relative to the head-mounted display device based on the position of the target projection point and the array position information can be: determining a first distance between the target projection point and the target light source unit in a first coordinate direction and a second distance in a second coordinate direction based on the position of the target projection point and the array position information; performing trigonometric function calculations on the first distance and the second distance to obtain the azimuth angle of the target light source unit relative to the head-mounted display device.

[0051] For example, Figure 4 As shown, the target light source unit n is located on the top surface of the rectangular box, and the head-mounted display device is projected onto the top surface of the rectangular box where the target light source unit is located to obtain the target projection point P. According to the position information of the head-mounted display device inside the rectangular box, the distance between the target projection point P and the first side surface is determined to obtain the third distance; the distance between the target light source unit and the first side surface is determined according to the array position information to obtain the fourth distance; the third distance is subtracted from the fourth distance to obtain the first distance x between the target projection point and the target light source unit in the first coordinate direction; according to the position information of the head-mounted display device inside the rectangular box, the distance between the target projection point P and the rear-view surface is determined to obtain the fifth distance; the distance between the target light source unit and the rear-view surface is determined according to the array position information to obtain the sixth distance; the second distance y between the target projection point and the target light source unit in the second coordinate direction is subtracted from the fifth distance. Get the trigonometric function formula Wherein, α is the azimuth angle, x is the first distance, and y is the second distance. The first distance and the second distance are calculated based on the trigonometric function formula to obtain the azimuth angle of the target light source unit relative to the head mounted display device.

[0052] In some embodiments, the method of determining the azimuth of the target light source unit relative to the head-mounted display device according to the position of the target projection point and the array position information can be: obtaining the reference light source unit closest to the target projection point and obtaining the array position information of the reference light source unit; determining the first distance in the first coordinate direction and the second distance in the second coordinate direction between the reference light source unit and the target light source unit according to the array position information of the reference light source unit and the target array position information; using the first distance as the distance between the target projection point and the target light source unit in the first coordinate direction, and using the second distance as the distance between the target projection point and the target light source unit in the second coordinate direction; performing trigonometric function calculation on the first distance and the second distance to obtain the azimuth of the target light source unit relative to the head-mounted display device. By approximately regarding the position of the reference light source unit closest to the projection point as the position of the target projection point, the efficiency of azimuth calculation can be effectively improved.

[0053] In some embodiments, the straight-line distance between the target projection point and the target light source unit is determined based on the position of the target projection point and the target array position information; the projection distance between the head-mounted display device and the target projection point is obtained; and trigonometric functions are performed on the straight-line distance and the projection distance to obtain the pitch angle of the target light source unit relative to the head-mounted display device.

[0054] It should be noted that the projection distance between the head mounted display device and the target projection point is the distance h between the head mounted display device and the top surface.

[0055] In some embodiments, the method for determining the straight-line distance between the target projection point and the target light source unit according to the position of the target projection point and the target array position information can be: according to the position of the target projection point and the array position information, determine the first distance between the target projection point and the target light source unit in the first coordinate direction and the second distance in the second coordinate direction, perform a right triangle calculation on the first distance and the second distance, and obtain the straight-line distance between the target projection point and the target light source unit.

[0056] Exemplarily, a first distance between the target projection point and the target light source unit in the first coordinate direction is determined to be x, and a second distance in the second coordinate direction is determined to be y, and a right triangle is formed between the first distance x and the second distance y. Calculate and obtain the straight-line distance l between the target projection point and the target light source unit, the projection distance h between the head-mounted display device and the target projection point, and obtain the trigonometric function formula Wherein, θ is the pitch angle, l is the straight-line distance between the target projection point and the target light source unit, and h is the projection distance between the head-mounted display device and the target projection point. The straight-line distance and the projection distance are calculated based on the trigonometric function formula to obtain the pitch angle of the target light source unit relative to the head-mounted display device.

[0057] In some embodiments, the light source unit includes a plurality of pixelated matrix light source units, each pixelated matrix light source unit is arranged in contact on the inner surfaces of the two side surfaces, the top surface and the bottom surface of the rectangular box, and each pixelated matrix light source unit is provided with unique array position information. Among them, the light source of the pixelated matrix light source unit can be selected according to actual conditions, and the embodiment of the present invention does not specifically limit this. For example, the pixelated matrix light source unit can be an LED matrix pixel lamp.

[0058] It is understandable that by setting a plurality of pixel matrix light source units on each surface of the rectangular box, or by covering each surface of the rectangular box with pixel matrix light source units, a continuous light source can be realized, and light sources of different areas and shapes can be set. This effectively solves the problem of the light source being affected by the volume of the light source and the spacing of the light source arrangement, and greatly improves the diversity of the light source.

[0059] For example, Figure 5 As shown, pixelated matrix light source units are arranged on the inner surfaces of the two side surfaces, top surface and bottom surface of the rectangular box (only part of the pixelated matrix light source units are drawn in the figure) to obtain a light source device.

[0060] In some embodiments, the light source device determines the target light source unit and the target light source shape of the target light source unit according to the light source control instruction, and controls the target light source unit to emit the target light of the target light source shape. The target light source unit is controlled to emit the target light of the target light source shape by the light source control instruction, which greatly improves the diversity of the detection light.

[0061] In some embodiments, the data processing unit of the head-mounted display device obtains array position information of the target pixelated matrix light source unit, and determines the spatial position information of the target pixelated matrix light source unit relative to the head-mounted display device based on the array position information.

[0062] It should be noted that the spatial position information of the target pixelated matrix light source unit relative to the head-mounted display device can be determined based on the array position information. The method of determining the spatial position information of the target light source unit relative to the head-mounted display device can be referred to the aforementioned method, and this application will not go into details about this.

[0063] The head-mounted display device detection system in the above embodiment includes a head-mounted display device and a light source device, the head-mounted display device includes a light intensity collection unit and a data processing unit, the light source device includes a plurality of light source units, and each light source unit is arranged in an array with equal intervals, wherein: the light source device receives a light source control instruction, and determines a target light source unit from a plurality of light source units according to the light source control instruction, and controls the target light source unit to operate so that the target light source unit irradiates target light; the light intensity collection unit collects the target light intensity of the target light irradiated by the light source unit; the data processing unit obtains the array position information of the target light source unit, and determines the spatial position information of the target light source unit relative to the head-mounted display device according to the array position information. In the present application, by arranging a plurality of light source units in an array with equal spacing in the light source device and controlling the target light source unit to irradiate the target light, the lighting illumination in most usage scenarios can be simulated. The target light intensity of the target light can be accurately collected by the light intensity collection unit, and the spatial position information of the target light source unit relative to the head-mounted display device can be accurately calculated based on the array position information of the target light source unit, which can provide accurate detection light data for subsequent updating of the parameters of the head-mounted display device, thereby greatly improving the display quality of the head-mounted display device and improving the user experience.
