[0003] Because laser light sources place higher demands on the quality of optical components, plastic optical components with large energy distribution in the optical path are at risk of burning out. Since plastic compound eye elements are crucial components in the optical path of traditional projection products, to avoid burn-out in the laser optical path, it is considered to replace plastic compound eye elements with glass compound eye elements.

[0077] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0078] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0079] In the description of this application, it should be noted that if the terms "upper", "lower", etc. appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this application is usually placed in, it is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0080] Furthermore, the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Additionally, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0081] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0082] In existing technologies, due to the higher quality requirements of laser light sources for optical components, plastic optical components with large energy distribution in the optical path are at risk of burning out. Since plastic compound eye elements are important components in the optical path of traditional projection products, to avoid burn-out in the laser optical path, it is considered to use glass compound eye elements instead of plastic compound eye elements.

[0083] To address manufacturing challenges and cost considerations, two single-sided glass compound eye elements are often combined to form a double-sided glass compound eye for use in projection products. However, aligning the geometric centers of the light spots presents a challenge when combining two single-sided glass compound eye elements. The accuracy of this alignment directly determines the projection quality of the projection product. Therefore, ensuring proper alignment of the geometric centers of the light spots from the two single-sided glass compound eye elements is crucial.

[0084] Based on this, this application proposes to provide a method for aligning multiple compound eye elements, which determines the positional deviation between the first and second light spots by using the parameters of the first light spot of the first compound eye element and the parameters of the second light spot of the multiple compound eye element composed of the first compound eye element and the target compound eye element, calculates the compound eye eccentricity of the target compound eye element based on the preset correspondence between the positional deviation and the compound eye eccentricity, and adjusts the position of the target compound eye element according to the compound eye eccentricity to achieve geometric center alignment of the light spots of the multiple compound eye elements.

[0085] Before providing a detailed description of the multi-compound eye element alignment method provided in this application, the structure of the multi-compound eye element alignment system used in this method will be explained in order to better understand the multi-compound eye element alignment method of this application.

[0086] Please refer to Figure 1 This is a schematic diagram of the structure of a multi-compound-eye element alignment system provided in an embodiment of this application, as shown below. Figure 1 As shown, the multi-compound eye element alignment system includes a numerical control system 10 and a light source generator 20. The numerical control system 10 includes a photodetector 11, a computer device 12, and a numerical control adjustment device 13. The numerical control adjustment device 13 is used to adjust the multi-compound eye element 30.

[0087] The light source generator 20 is used to emit light and generate a light spot on the photodetector 11 through the multi-compound eye element 30; the photodetector 11 is used to collect the parameters of the first light spot of the first compound eye element 31 in the multi-compound eye element 30; the photodetector 11 is also used to collect the parameters of the second light spot of the multi-compound eye element 30; the computer device 12 is used to determine the positional deviation of the first light spot and the second light spot according to the parameters of the first light spot and the second light spot, and to determine the compound eye eccentricity of the target compound eye element 32 according to the relationship between the positional deviation and the compound eye eccentricity, so as to adjust the position of the target compound eye element 32 in the multi-compound eye element 30 through the numerical control adjustment device 13 until the geometric center of the light spot of the multi-compound eye element 30 is aligned.

[0088] In this embodiment, the photodetector 11 is a device that uses the photoelectric effect to detect optical information and convert it into electrical information, such as a charge-coupled device (CCD). The photodetector 11 includes multiple detection screens composed of optical detection elements. Light passing through the geometric center of the first compound eye element 31 can form a first light spot on the detection screen of the photodetector, and light passing through the geometric center of the multiple compound eye elements 32 can form a second light spot on the detection screen of the photodetector. The photodetector 11 can determine the parameters of the first light spot on the detection screen based on the optical information of the first light spot, and determine the parameters of the second light spot on the detection screen based on the optical information of the second light spot. The photodetector 11 can send the parameters of the first light spot and the second light spot to the computer device 12, so that the computer device 12 can calculate the parameters of the first light spot and the second light spot, determine the compound eye eccentricity of the target compound eye element 32, and send adjustment information to the data adjustment device 13. In this context, the target compound eye element 32 refers to the other compound eye elements in the multi-compound eye element 30 besides the first compound eye element 31. The multi-compound eye element 30 can be composed of two single-sided compound eye elements or other numbers of single-sided compound eye elements. Taking two single-sided compound eye elements as an example, the first compound eye element 31 in the multi-compound eye element 30 is the reference compound eye element, and the other compound eye element, namely the target compound eye element 32, is the compound eye element to be adjusted. The position of the first compound eye element remains unchanged, and only the position of the target compound eye element 32 is adjusted to align the geometric centers of the light spots of the first compound eye element 31 and the target compound eye element 32.

[0089] The numerical control adjustment device 13 includes a fixing component and an adjustment component. The fixing component is used to fix the compound eye element 30, and the adjustment component can adjust the position of the target compound eye element 32 according to the adjustment information of the computer device 12.

[0090] The light source generator 20 is used to generate a light source and forms a light spot on the detection surface of the photodetector 11 through the geometric center of the light spot of the first compound eye element and the geometric center of the light spot of the multiple compound eye elements. In this embodiment, the light source generator 20 can be, for example, a laser light source generator to generate a laser light source.

[0091] Based on the aforementioned multi-compound-eye element alignment system, the system may further include a beam collimation device 40 and an imaging device 50. The beam collimation device 40 is positioned between the light source generator 20 and the multi-compound-eye element 30 to protect the multi-compound-eye element and collimate the light source from the light source generator. The imaging device 50 is positioned between the multi-compound-eye element 30 and the photodetector 11 to process the light spot passing through the multi-compound-eye element 30, resulting in a better and clearer image of the light spot on the detection surface of the photodetector 11. Both the beam collimation device 40 and the imaging device 50 can be lens assemblies composed of multiple lenses.

[0092] To ensure the accuracy of aligning the geometric center of the light spot of the compound eye element, all other parts of the compound eye element alignment system except the computer equipment are fixed on the mounting platform 60.

[0093] Based on the above-described multi-compound eye element alignment system, this application provides a multi-compound eye element alignment method executed by a computer device in the above-described multi-compound eye element alignment system.

[0094] Please refer to Figure 2 This is a flowchart illustrating a method for aligning multiple compound eye elements according to an embodiment of this application. Figure 2 As shown, the method includes:

[0095] S10: Obtain the parameters of the first light spot of the first compound eye element in the multi-compound eye element, which is collected by the photodetector.

[0096] In this embodiment, the first compound eye element in the multi-compound eye element is placed on the fixed part of the numerical control adjustment device. The position of the first compound eye element is adjusted so that the light source generated by the light source generator passes through the central compound eye of the first compound eye element and forms a first light spot on the photodetector. The photodetector determines the parameters of the first light spot based on the light information of the first light spot on the photodetector and sends the parameters of the first light spot to the computer device.

[0097] In one alternative embodiment, before the light passes through the first compound eye element, the light generated by the light source generator is perpendicularly struck onto the detection surface of the photodetector, and the center position of the light on the detection surface is captured and defined as the center of the image. Then, the light passes through the first compound eye element and forms a first light spot on the detection surface. The parameters of the first light spot are determined based on its positional offset relative to the center of the image.

[0098] S20: Obtain the parameters of the second light spot of the photodetector as it passes through the compound eye element.

[0099] In this embodiment, after obtaining the parameters of the first light spot, the position of the first compound eye element is fixed, and the second compound eye element is placed on the fixed component of the numerical control adjustment device. The first and second compound eye elements constitute a multi-compound eye element, so that the light source generated by the light source generator passes through the central compound eye of the multi-compound eye element and forms a second light spot on the photodetector. The photodetector determines the parameters of the second light spot based on the light information of the second light spot on the photodetector and sends the parameters of the second light spot to the computer device. For example, the parameters of the second light spot can be determined based on the positional offset of the second light spot relative to the center of the image.

[0100] It should be noted that, in order to ensure that the initial positional deviation between the first compound eye element and the second compound eye element is within a preset range, the initial compound eye eccentricity of the first compound eye element and the second compound eye element can be ensured to be within half the compound eye size when placing the second compound eye element.

[0101] S30: Based on the parameters of the first light spot and the second light spot, determine whether the geometric centers of the light spots of the multi-compound eye element are aligned.

[0102] In this embodiment, the parameters of the first light spot include: the center of the first light spot at a first position on the detection surface of the photodetector; the parameters of the second light spot include: the center of the second light spot at a second position on the detection surface of the photodetector. The first and second positions can be, for example, the positions of the first and second light spots relative to the center of the image, respectively. If the first and second positions do not coincide, it is determined that the geometric centers of the light spots of the multi-compound eye element are misaligned; if the first and second positions coincide, it is determined that the geometric centers of the light spots of the multi-compound eye element are aligned.

[0103] S40: If misaligned, calculate the compound eye eccentricity of the target compound eye element based on the positional deviation of the first and second light spots, as well as the preset correspondence between the positional deviation and the compound eye eccentricity.

[0104] In this embodiment, if the geometric centers of the light spots of the multiple compound eye elements are not aligned, it is necessary to determine the compound eye eccentricity between the first and second compound eye elements. Since the compound eye eccentricity between the first and second compound eye elements cannot be determined by measurement, the compound eye eccentricity of the target compound eye element can be determined by calculating the positional deviation between the first and second light spots based on the correspondence between the positional deviation of the light spots and the compound eye eccentricity.

[0105] The pre-defined relationship between positional deviation and compound eye eccentricity was obtained by fitting the experimental positional deviation and the manually adjusted compound eye eccentricity.

[0106] S50: Based on the compound eye eccentricity, adjust the position of the target compound eye element through a numerical control adjustment device until the geometric center of the light spot of the multiple compound eye elements is aligned.

[0107] In this embodiment, after the computer device calculates the compound eye eccentricity of the target compound eye element based on the correspondence between the positional deviation and the compound eye eccentricity, it sends an adjustment signal to the numerical control adjustment device based on the compound eye eccentricity, so that the numerical control adjustment device adjusts the position of the target compound eye element based on the adjustment signal. Steps S20-S50 are repeated until the geometric centers of the light spots of the multiple compound eye elements are aligned.

[0108] The multi-compound eye element alignment method provided in this application embodiment obtains parameters of the first light spot of the first compound eye element through the light collected by the photodetector; obtains parameters of the second light spot of the multi-compound eye element through the light collected by the photodetector; determines whether the geometric centers of the light spots of the multi-compound eye elements are aligned based on the parameters of the first and second light spots; if they are not aligned, calculates the compound eye eccentricity of the target compound eye element based on the positional deviation of the first and second light spots and a preset correspondence between the positional deviation and the compound eye eccentricity; and adjusts the position of the target compound eye element using a numerically controlled adjustment device based on the compound eye eccentricity until the geometric centers of the light spots of the multi-compound eye elements are aligned. In the solution of this application embodiment, the compound eye eccentricity of the target compound eye element can be determined based on the positional deviation of the first and second light spots and the correspondence between the positional deviation and the compound eye eccentricity, so that by adjusting the position of the target compound eye element, the geometric centers of the light spots of the multi-compound eye elements are aligned, thereby optimizing the optical effect of the multi-compound eye elements and improving the projection effect of the projection product.

[0109] The above embodiments provide a method for determining the parameters of the first light spot and the second light spot based on the center of the image. This application embodiment also provides another method for determining the parameters of the first light spot and the second light spot.

[0110] Please refer to Figure 3 This is a flowchart illustrating another method for aligning multiple compound eye elements provided in an embodiment of this application, as shown below. Figure 3 As shown, the above S30 includes:

[0111] S31: Establish a coordinate system with the first position as the origin.

[0112] In this embodiment, a coordinate system is established with the first position of the first light spot on the detection surface as the origin. This coordinate system is a three-dimensional coordinate system, in which the X-axis is the horizontal direction perpendicular to the light, the Y-axis is the vertical direction perpendicular to the light, and the Z-axis is the direction of the light.

[0113] S32: Determine the position coordinates of the second position in the coordinate system.

[0114] In this embodiment, the coordinate position of the second light spot in the coordinate system is determined based on the second position of the second light spot on the detection surface.

[0115] S33: Determine the positional deviation of the light spot center based on the position coordinates.

[0116] In this embodiment, based on the position coordinates of the second coordinate in the coordinate system, the position deviation in the coordinate system is determined to include the deviation along the X-axis, the deviation along the Y-axis, and / or the deviation along the Z-axis.

[0117] The parameters of the first light spot include: the center size of the first light spot, and the parameters of the second light spot include: the center size of the second light spot.

[0118] S34: Determine whether the geometric center of the light spot of the compound eye element is aligned based on the positional deviation.

[0119] In this embodiment, if there is a non-zero deviation along the X-axis, Y-axis and / or Z-axis, it is determined that the geometric center of the light spot of the multi-compound eye element is not aligned; if the deviations along the X-axis, Y-axis and / or Z-axis are all zero, it is determined that the center of the light spot set of the multi-compound eye element is aligned.

[0122] Please refer to Figure 4 This is a flowchart illustrating another method for aligning multiple compound eye elements provided in an embodiment of this application, as shown below. Figure 4 As shown, the above S40 includes:

[0123] S41: If the positional deviation includes: horizontal positional deviation perpendicular to the light, calculate the horizontal compound eye eccentricity of the target compound eye element according to the preset correspondence between the horizontal positional deviation and the compound eye eccentricity.

[0124] In this embodiment, the positional deviation of the light spot center determined based on the position coordinates includes the horizontal positional deviation perpendicular to the light rays. A preset correspondence between the horizontal positional deviation and the compound eye eccentricity is used to calculate the horizontal compound eye eccentricity of the target compound eye element. The preset correspondence between the horizontal positional deviation and the compound eye eccentricity can be determined by linear fitting of experimental horizontal positional deviations and experimental compound eye eccentricities, or by training an initial horizontal eccentricity adjustment model based on experimental horizontal positional deviations and experimental compound eye eccentricities to obtain a horizontal eccentricity adjustment model. This horizontal eccentricity adjustment model is used to characterize the preset correspondence between the horizontal positional deviation and the compound eye eccentricity.

[0125] For example, please refer to Figure 5 This is a schematic diagram of a horizontal position deviation provided in an embodiment of this application, as shown below. Figure 5 As shown, the second light spot deviates from the first light spot only in the horizontal direction perpendicular to the light rays. This application provides a preset horizontal position deviation. and compound eye eccentricity The correspondence can be:

[0126]

[0127] in, Positional deviation By taking the inverse function of the above correspondence, the eccentricity of the compound eye can be obtained. After determining the distances between the devices in the multi-compound eye alignment system, the horizontal compound eye eccentricity coefficient can be fitted experimentally. The value can be adjusted, and a higher-order correspondence can be fitted based on the adjustment precision. This application is not limited to... .

[0128] S42: If the positional deviation includes: vertical positional deviation perpendicular to the light, calculate the vertical compound eye eccentricity of the target compound eye element according to the preset correspondence between the vertical positional deviation and the compound eye eccentricity.

[0129] In this embodiment, the positional deviation of the light spot center determined based on the position coordinates includes the vertical positional deviation perpendicular to the light rays. A preset correspondence between the vertical positional deviation and the compound eye eccentricity is used to calculate the vertical compound eye eccentricity of the target compound eye element. The preset correspondence between the vertical positional deviation and the compound eye eccentricity can be determined by linear fitting of experimental vertical positional deviations and experimental compound eye eccentricities, or by training an initial vertical eccentricity adjustment model based on experimental vertical positional deviations and experimental compound eye eccentricities to obtain a vertical eccentricity adjustment model. This vertical eccentricity adjustment model is used to characterize the preset correspondence between the vertical positional deviation and the compound eye eccentricity.

[0130] For example, please refer to Figure 6 This is a schematic diagram of a vertical position deviation provided in an embodiment of this application, as shown below. Figure 6 As shown, the second light spot deviates from the first light spot only in the direction perpendicular to the light rays. This application provides a preset vertical position deviation. and compound eye eccentricity The correspondence can be:

[0131]

[0132] in, Positional deviation By taking the inverse function of the above correspondence, the eccentricity of the compound eye can be obtained. After determining the distances between the devices in the multi-compound eye alignment system, the vertical compound eye eccentricity coefficient can be fitted experimentally. The value can be adjusted, and a higher-order correspondence can be fitted based on the adjustment precision. This application is not limited to... .

[0133] S43: If the positional deviation includes: parallel positional deviation parallel to the light, calculate the parallel compound eye eccentricity of the target compound eye element according to the preset correspondence between the parallel positional deviation and the compound eye eccentricity.

[0134] In this embodiment, the positional deviation of the light spot center determined based on the position coordinates includes the parallel positional deviation parallel to the light rays. A preset correspondence between the parallel positional deviation and the compound eye eccentricity is used to calculate the horizontal compound eye eccentricity of the target compound eye element. The preset correspondence between the parallel positional deviation and the compound eye eccentricity can be determined by linear fitting of experimental parallel positional deviations and experimental compound eye eccentricities, or by training an initial parallel eccentricity adjustment model based on experimental parallel positional deviations and experimental compound eye eccentricities to obtain a parallel eccentricity adjustment model. This model characterizes the preset correspondence between the parallel positional deviation and the compound eye eccentricity.

[0135] For example, please refer to Figure 7 This is a schematic diagram of a parallel position deviation provided in an embodiment of this application, as shown below. Figure 7 As shown, the second light spot and the first light spot are not deviated in the x and y directions, but there is a deviation along the optical axis, i.e., the Z-axis direction, meaning there is an air gap between the first compound eye element and the target compound eye element. This application provides a preset parallel position deviation. and compound eye eccentricity The correspondence can be:

[0136]

[0137] in, Positional deviation The positional deviation can be calculated based on the center dimensions of the first and second light spots. In this embodiment, the positional deviation is directly taken as half of the long side of the first light spot. By taking the inverse function of the above correspondence, the compound eye eccentricity can be obtained. After determining the distances between the devices in the multi-compound eye alignment system, the parallel compound eye eccentricity coefficient can be fitted experimentally. The value can be adjusted, and a higher-order correspondence can be fitted based on the adjustment precision. This application is not limited to... .

[0138] It should be noted that although S41-S43 above have a sequential execution order in the flowchart, in actual application, the compound eye eccentricity is calculated directly by substituting the corresponding position deviation and the corresponding relationship between the position deviation and the compound eye eccentricity, and there is no sequential order.

[0139] Furthermore, the target compound eye element and the first compound eye element have a positional deviation along the Z-axis, and the plane of the target compound eye element may not be perpendicular to the light ray. For example, Figure 8 This is a schematic diagram illustrating the tilt of a target compound eye element as provided in an embodiment of this application. Whether the plane of the target compound eye element is not perpendicular to the light ray can be determined based on the following correspondence.

[0140]

[0141] in, Positional deviation By taking the inverse function of the above correspondence, the eccentricity of the compound eye can be obtained. If the value of the compound eye eccentricity exceeds the preset threshold, it indicates a serious problem with the plane of the target compound eye element not being perpendicular to the light rays. In this case, the deviation of the geometric center of the light spot of the multi-compound eye element is large, and it is unnecessary to adjust the position of the target compound eye element through the CNC adjustment device; manual adjustment can be performed first. If the value of the compound eye eccentricity does not exceed the preset threshold, the parallel compound eye eccentricity can be determined using S43, and the position of the target compound eye element can be adjusted once. Then, further adjustments can be made using S41-S43. After determining the distance between each device in the multi-compound eye element alignment system, the tilted compound eye eccentricity coefficient can be fitted experimentally. The value can be adjusted, and a higher-order correspondence can be fitted based on the adjustment precision. This application is not limited to... .

[0142] It should be noted that, This includes horizontal and parallel positional deviations, or vertical and parallel positional deviations. It can also be and simultaneous equations, or and The simultaneous equations.

[0143] After adjusting the position of the target compound eye elements using the above method to align the geometric centers of the light spots of the multiple compound eye elements, it is necessary to determine whether the multiple compound eye elements are tilted together, that is, the centers of the first light spot and the second light spot are not deviated, but there is an angle between the multiple compound eye elements and the light rays. For example, Figure 9 The schematic diagram of a tilted compound eye element provided in the embodiment of this application requires the following correspondence to determine whether there is an angle between the compound eye element and the light ray.

[0144]

[0145] in, Positional deviation By taking the inverse function of the above correspondence, the tilt angle of the compound eye element can be obtained. If it is determined that there is an angle between the compound eye element and the light ray, the positions of both the first compound eye element and the target compound eye element need to be adjusted.

[0146] After determining the distances between the devices in the multi-compound eye alignment system, the eccentricity coefficient of the compound eye angle can be fitted experimentally. The value can be adjusted, and a higher-order correspondence can be fitted based on the adjustment precision. This application is not limited to... .

[0147] In one possible implementation, when the compound eye element is perpendicular to the light beam, the energy distribution of the light spot from the center to the edge is red-orange-yellow-green-blue, with the energy decreasing sequentially from the center to the edge, resulting in a uniform energy distribution. When the compound eye element is tilted, the energy distribution of the light spot becomes uneven, and the energy is more concentrated at the center of the light spot.

[0148] After light passes through the compound eye element and forms a second light spot on the detection surface of the photodetector, the energy distribution of the second light spot is acquired. If the energy distribution is significantly uneven or concentrated in the center of the second light spot, it is determined that there is a tilt between the compound eye element and the light source. The tilt angle of the compound eye element is determined by substituting the offset of the light spot center into the above correspondence. The offset of the light spot center can be determined as follows: the light source generated by the light source generator is perpendicularly projected onto the detection surface of the photodetector. The center position of the light on the detection surface is determined as the center of the image. A coordinate system is established with this center as the origin. After the light passes through the compound eye element and forms a light spot on the detection surface of the photodetector, the offset of the light spot center relative to the origin is determined.

[0149] For example, please refer to Figures 10(a)-10(d) Figure 10(a) shows the energy distribution of the light spot under four tilt conditions provided in the embodiments of this application, with the center coordinates of the light spot being (0,0) and the tilt angle being zero; Figure 10(b) shows the center coordinates of the light spot being (0,0.25) and the tilt angle being 0.1; Figure 10(c) shows the center coordinates of the light spot being (0,0.26) and the tilt angle being 0.3; Figure 10(d) shows the center coordinates of the light spot being (0,0.42) and the tilt angle being 0.5. It can be seen that the greater the offset of the center of the light spot from the origin of the coordinate system and the greater the tilt angle, the more uneven the energy distribution becomes, and the more concentrated it is at the center of the light spot.

[0150] If the offset of the light spot center is in the X-axis direction, the tilt angle is determined to be an horizontal tilt between the compound eye element and the light ray. If the offset of the light spot center is in the Y-axis direction, the tilt angle is determined to be a vertical tilt between the compound eye element and the light ray. The numerical control adjustment device can adjust the compound eye element along the corresponding direction according to the tilt angle until the compound eye element is perpendicular to the light ray.

[0151] The multi-compound eye element alignment method provided in this application embodiment includes the following steps: if the positional deviation includes a horizontal positional deviation perpendicular to the light source, the horizontal compound eye eccentricity of the target compound eye element is calculated based on a preset correspondence between the horizontal positional deviation and the compound eye eccentricity; if the positional deviation includes a vertical positional deviation perpendicular to the light source, the vertical compound eye eccentricity of the target compound eye element is calculated based on a preset correspondence between the vertical positional deviation and the compound eye eccentricity; if the positional deviation includes a parallel positional deviation parallel to the light source, the parallel compound eye eccentricity of the target compound eye element is calculated based on a preset correspondence between the parallel positional deviation and the compound eye eccentricity. In the solution of this application embodiment, the compound eye eccentricity in the horizontal, vertical, and parallel directions can be determined by calculating the positional deviations, accurately adjusting the position of the target compound eye element, and ensuring that the geometric centers of the light spots of the multi-compound eye elements are aligned.

[0152] Based on the above embodiments, this application further provides a method for adjusting the position of the target compound eye element.

[0153] Please refer to Figure 11 This is a flowchart illustrating another method for aligning multiple compound eye elements provided in an embodiment of this application, as shown below. Figure 11 As shown, the above S50 includes:

[0154] S51: Based on the compound eye eccentricity in the first direction, adjust the position of the target compound eye element along the first direction using a numerical control adjustment device.

[0155] In this embodiment, when it is determined that there is a positional deviation in the first direction between the first light spot and the second light spot, the positional deviation in the first direction is determined according to the preset correspondence between the positional deviation and the compound eye eccentricity, and the computer device sends the adjustment information to the numerical control adjustment device. The adjustment information includes the adjustment direction and the adjustment amount. The numerical control adjustment device adjusts the position of the target compound eye element along the first direction according to the adjustment information.

[0156] Furthermore, if the positional deviation includes a horizontal positional deviation perpendicular to the light, the horizontal compound eye eccentricity of the target compound eye element is calculated based on the preset correspondence between the horizontal positional deviation and the compound eye eccentricity. Then, based on the compound eye eccentricity in the horizontal direction, the position of the target compound eye element is adjusted along the horizontal direction perpendicular to the light by a numerical control adjustment device.

[0157] S52: Based on the compound eye eccentricity in the second direction, adjust the position of the target compound eye element along the second direction using a numerical control adjustment device.

[0158] In this embodiment, when it is determined that there is a positional deviation in the second direction between the first light spot and the second light spot, the positional deviation in the second direction is determined according to the preset correspondence between the positional deviation and the compound eye eccentricity, and the computer device sends the adjustment information to the numerical control adjustment device. The adjustment information includes the adjustment direction and the adjustment amount. The numerical control adjustment device adjusts the position of the target compound eye element along the second direction according to the adjustment information.

[0159] Furthermore, if the positional deviation includes a vertical positional deviation perpendicular to the light, the vertical compound eye eccentricity of the target compound eye element is calculated based on the preset correspondence between the vertical positional deviation and the compound eye eccentricity. Then, based on the compound eye eccentricity in the vertical direction, the position of the target compound eye element is adjusted along the horizontal direction perpendicular to the light by a numerical control adjustment device.

[0160] S53: Based on the compound eye eccentricity in the third direction, adjust the position of the target compound eye element along the third direction using a numerical control adjustment device.

[0161] In this embodiment, when it is determined that there is a third-direction positional deviation between the first light spot and the second light spot, the third-direction compound eye eccentricity corresponding to the third-direction positional deviation is determined according to the preset correspondence between the positional deviation and the compound eye eccentricity. The computer device sends the adjustment information to the numerical control adjustment device. The adjustment information includes the adjustment direction and the adjustment amount. The numerical control adjustment device adjusts the position of the target compound eye element along the third direction according to the adjustment information.

[0162] Furthermore, if the positional deviation includes: parallel positional deviation parallel to the light, the parallel compound eye eccentricity of the target compound eye element is calculated based on the preset correspondence between the parallel positional deviation and the compound eye eccentricity, and the position of the target compound eye element is adjusted along the light direction by a numerical control adjustment device based on the compound eye eccentricity in the parallel direction.

[0163] It should be noted that although S51-S53 above includes adjusting the position of the target compound eye element in three directions, this does not mean that the target compound eye element must be adjusted in all three directions in actual application. Instead, adjustments are made along the corresponding directions based on the actual eccentricity of the compound eye in one or more directions. Furthermore, although the flowchart shows a sequential execution order, in actual application, the position of the target compound eye element is directly adjusted based on the calculated compound eye eccentricity, without any specific order. If there are compound eye eccentricities in multiple directions, the position of the target compound eye element is adjusted sequentially from those directions.

[0164] The multi-compound eye element alignment method provided in this application adjusts the position of the target compound eye element along the first direction using a numerically controlled adjustment device based on the compound eye eccentricity in the first direction; adjusts the position of the target compound eye element along the second direction using a numerically controlled adjustment device based on the compound eye eccentricity in the second direction; and adjusts the position of the target compound eye element along the third direction using a numerically controlled adjustment device based on the compound eye eccentricity in the third direction. The solution in this application embodiment can adjust the position of the target compound eye element from multiple directions, thereby ensuring the alignment of the geometric center of the light spot of the multi-compound eye element, thus optimizing the optical effect of the multi-compound eye element and improving the projection effect of the projection product.
