Figure 2 , Attachment Figure 3 And attached Figure 7 , the second carrier 5 and the third carrier 6 need to provide motion support in the first direction a and the second direction b, and thus in this embodiment, the second carrier 5 and the third carrier 6 can be set as rectangular frames, but not limited to; the first carrier 8 needs to provide a turning space for the bearing portion 81, and thus in this embodiment, the first carrier 8 can be set as a U-shaped frame with an upper opening, but not limited to; the bearing portion 81 can be a supporting plate, a supporting frame, etc., and the bearing portion 81 is rotated around the first direction a and is arranged on the first carrier 8, and thus can be rotated to keep the glass to be tested 2 being carried at its corresponding installation angle, for example: an angle of 0-80 degrees with the horizontal plane; in this embodiment, the area to be tested on the glass to be tested 2 is slightly different according to the model of the product, mainly the area where the glass to be tested 2 is in the installation angle state on the vehicle corresponding to the driver's line of sight that is prone to secondary image deviation, which is easily understood by those skilled in the art, and will not be described in detail here; in this embodiment, relevant presets can be made in the processor or relevant coordinate information can be manually input to clarify the position of the area to be tested, so as to pave the way for accurately controlling the correspondence between the main image and the position of the point to be tested.

The connection between the first image acquisition device 3 and it can be bolted, bonded, clamped, etc. The two rotating mounting parts 31 are arranged at intervals along the second direction b. The first image acquisition device 3 can be installed on a certain rotating mounting part 31 according to actual detection needs. The fields of view of the two rotating mounting parts 31 in the second direction b can at least be connected to each other, or even partially cover each other, so that a certain position can be selected to acquire the first image corresponding to different installation angles of the glass 2 to be tested. For example: when the installation angle of the glass 2 to be tested is less than 30 degrees, the rotating mounting part 31 below the second carrier 5 can be selected to set the first image acquisition device 3. Correspondingly, when the installation angle of the glass 2 to be tested is greater than or equal to 30 degrees, the rotating mounting part 31 above the second carrier 5 can be selected to set the first image acquisition device 3.

[0072] Further, see Attachment Figure 7 , Attachment Figure 8 and attached Fig. 9 In the secondary image deviation value measuring device provided in this embodiment, in a specific implementation, the first supporting frame 8 includes a support 82; a connecting portion 83 is provided on the support 82 to rotate around the first direction a, and the connecting portion 83 is used to connect the supporting portion 81 so that the supporting portion 81 can rotate around the first direction a; the supporting portion 81 includes a first frame 811, a second frame 812, a third frame 813 and a fourth frame 814; the first frame 811 and the second frame 812 are arranged opposite to each other and spaced apart along the first direction a, the first frame 811 and / or the second frame 812 are connected to the connecting portion 83, and the first frame 811 faces the second frame 812. One side of the second frame 812 and the side of the second frame 812 facing the first frame 811 are sequentially provided with a plurality of limiting portions 815 along the extension direction thereof; the third frame 813 and the fourth frame 814 are movably arranged between the first frame 811 and the second frame 812 corresponding to the two ends of the first frame 811 respectively, and the third frame 813 and the fourth frame 814 are adapted to the limiting portions 815; wherein, a side of the third frame 813 facing the fourth frame 814 and a side of the fourth frame 814 facing the third frame 813 are respectively provided with supporting plates 816 for supporting two opposite edges of the glass 2 to be tested.

[0073] Specifically, in order to realize the flipping of the bearing part 81 relative to the horizontal plane, in this embodiment, the first bearing frame 8 is configured to include a support 82 and a connecting part 83; the support 82 is a rigid structure, which can be but not limited to a U-shaped frame with an upper opening, and the connecting part 83 can be a rotating shaft structure. In this embodiment, in order to simplify the driving operation, the connecting part 83 can be configured in the form of a small gear 831 driving a large gear 832, and the axis of the small gear 831 is led outward from the support 82 and connected to the driving rod 833, and the small gear 831 is meshed with the large gear 832, and the large gear 832 is rotated along the first direction. The side of the drive rod 833 a away from the drive rod 833 is fixedly connected to the bearing part 81 through the connecting plate 834, and then when the drive rod 833 drives the small gear 831 to rotate, the large gear 832 can indirectly drive the bearing part 81 to rotate at a larger angle, which greatly reduces the input of the driving force. It can be understood that the driving force of the drive rod 833 can be controlled manually or electrically; and the connecting part 83 can be only arranged on one side of the support 82 along the first direction a, and the other side along the first direction a can only be provided with a rotating shaft, or the connecting part 83 can be simultaneously arranged on both sides of the support 82 in the first direction a. It can also be understood that in order to match the installation angle of the glass 2 to be tested and avoid unnecessary flipping, in this embodiment, a limit rod 84 can be arranged at the connecting part 83, and the setting position of the limit rod 84 can be designed and adjusted according to actual needs; a detection sensor 85 can also be arranged on the limit rod 84, which can be but not limited to an angle sensor, a position sensor, etc., to improve the precise control of the flip angle of the bearing part 81, especially when the drive rod 833 is rotated in cooperation with manual driving. At the same time, in order to be suitable for the glasses 2 to be tested of different sizes and specifications, the bearing part 81 is set to be variable in size in this embodiment. The first frame 811, the second frame 812, the third frame 813, the fourth frame 814, and the supporting plate 816 are all rigid structures. The first frame 811, the second frame 812, the third frame 813, and the fourth frame 814 can be but not limited to a straight rod structure. The first frame 811 and the second frame 812 are respectively connected to the two sides of the first direction a of the support 82, that is, the connecting part 83. The lower ends of the first frame 811 and the second frame 812 are provided with a limiting part 815. The limiting part 815 can be but not limited to a limiting groove, a limiting block, a limiting column, a limiting hole, etc. The limiting parts 815 on the first frame 811 and the second frame 812 can be one or two. For example: Figure 7 As shown, taking the first frame 811 as an example, a limiting hole is set on the upper part of the first frame 811, and the third frame 813 is locked by a limiting pin. A limiting groove is set on the lower part of the first frame 811, and it is detachably connected to the third frame 813 and the fourth frame 814 through a limiting portion 815, and then the limiting pin can be adjusted to lock the fourth frame 814, so that the third frame 813 and the fourth frame 814 can be close to or away from each other, thereby adjusting the supporting range.

[0074] Accordingly, refer to the attached Fig.10 The measuring method of the secondary image deviation value measuring device provided in the embodiment of the present application is as follows, comprising the following steps:

[0075] 101. Control the light source 1 to illuminate the area to be tested on the glass 2 to be tested;

[0076] Specifically, the processor (not shown in the figure) controls the light source 1 to translate along the first direction a or the second direction b on the second carrier 5, or controls the light source 1 to rotate around the first direction a or the second direction b on the second carrier 5, so that the light emitted by it can be irradiated on the test area of ​​the glass 2 to be tested, specifically, irradiated on the test point in the test area to generate a primary image and a secondary image corresponding to the test point. The second carrier 5 is a mounting structure of the light source 1, which is a rigid structure, which can be a frame structure, a platform structure, a table structure, etc. The light source 1 can be movably arranged on it through a sliding member. In this embodiment, the first direction a and the second direction b can be horizontal and vertical directions respectively, and can also be adjusted accordingly according to the actual detection position, then the first direction a and the second direction b can also have a specified angle between each other; in this embodiment, the light source 1 can emit detection light horizontally in the horizontal direction and in the direction with a specified angle to the horizontal direction, and can also emit detection light vertically in the vertical direction and in the direction with a specified angle to the vertical direction. In this embodiment, controlling the light source 1 to rotate around the first direction a is the pitch angle adjustment, and the adjustable range can be but not limited to ±15°. The light source 1 rotates around the second direction b is the horizontal rotation adjustment, and the adjustable range can be but not limited to ±20°. The above angle range can be designed and adjusted according to actual needs. In this embodiment, the area to be tested on the glass to be tested 2 is slightly different according to the model of the product. It is mainly that the glass to be tested 2 is in the state of installation angle (angle with the horizontal plane 0-80 degrees) on the vehicle, which corresponds to the area within the driver's line of sight that is easy to produce secondary image deviation. This area is easy to understand for those skilled in the art, and no more details are given here. In this embodiment, relevant presets can be made in the processor or relevant coordinate information can be manually input to clarify the position of the area to be tested, paving the way for accurately controlling the correspondence between the main image and the position of the point to be tested. When controlling the light source 1 to emit light to the area to be tested, the approximate direction and area position can be judged by the human eye through the processor for manual drive control. The post-processor can control the light source 1 to irradiate the point to be tested according to the accurate coordinate information of the point to be tested in the area to be tested, so as to ensure the accuracy of the detection process and the detection results. In this embodiment, the light source 1 can be, but is not limited to, a laser emitter, and its signal is connected to the processor so that it can emit light according to the control signal. In this embodiment, the number of points to be tested in the test area can be designed and adjusted according to actual needs, and the processor automatically controls the light source 1 to perform irradiation detection one by one, which greatly improves the detection rate.

[0077] 102. Control the first image acquisition device 3 to acquire a first image of the area to be measured, and adjust the position of the light source 1 according to the first image until the light source 1 illuminates the point to be measured in the area to be measured;

[0078] Specifically, in order to ensure that the light source 1 can accurately illuminate the point to be tested, the first image acquisition device 3 is used in this embodiment to mark and calibrate the light source 1, that is, the first image acquisition device 3 is controlled by the processor to acquire the first image of the area to be tested illuminated by the light source 1, and the image processing is performed on the first image to determine whether the light source 1 is irradiated on the point to be tested. In this embodiment, the first image acquisition device 3 can be but is not limited to a panoramic camera. It can be understood that in this embodiment, the second image acquisition device 4 is used to acquire the second image on the second side of the glass to be tested 2, and the first image acquisition device 3 is used to acquire the first image on the first side opposite to the second side of the glass to be tested 2. After the first image is acquired in 102, the following steps are specifically included:

[0079] 201. Control the first image acquisition device 3 to acquire a first image of a to-be-tested area;

[0080] Specifically, in this process, the first image may include the overall outline of the glass to be tested, or may only include the area to be tested; the acquisition position of the first image by the first image acquisition device 3 may be manually adjusted according to actual needs, such as manually rotating or flipping the shooting angle of the first image acquisition device 3.

[0081] 202. Generate first virtual coordinates according to the first image acquisition device 3 and determine the coordinate value of the point to be measured corresponding to the first image;

[0082] Specifically, a first virtual coordinate system can be established for the first image acquisition device 3 in the processor. For example, the first virtual coordinate system is generated with the center of the field of view of the first image acquisition device 3 as the origin. Then, when the processor processes the first image, corresponding coordinate values ​​can be generated in the first virtual coordinate system for the area to be measured and the point to be measured.

[0083] 203. Generate a second virtual coordinate according to the movable space of the light source 1;

[0084] Specifically, the light source 1 can be rotated along the first direction a and the second direction b on the second carrier 5, or around the first direction a and the second direction b, that is, the movable range is its movable space. In this embodiment, the processor can generate a second virtual coordinate system with the center of the second carrier 5 as the origin, and the light source 1 can generate corresponding coordinate values ​​after moving on the second carrier 5. The processor can automatically generate the coordinate values ​​in the second virtual coordinate system where the light source 1 is located according to the movement control of the light source 1;

[0085] 204. Control the light source 1 to move until it illuminates the point to be measured in the first image, and determine a mapping relationship between the first virtual coordinate and the second virtual coordinate according to the coordinate value of the point to be measured in the first virtual coordinate system and the coordinate value of the light source in the second virtual coordinate system;

[0086] Specifically, in order to ensure the accuracy of the detection process and the detection results, in this embodiment, the light source 1 is controlled to emit a detection light to the point to be measured in the area to be measured, and the first image is acquired in real time. The processor processes the first image to determine whether the light irradiation point coincides with the point to be measured in the first virtual coordinate system. If not, the position of the light source 1 is adjusted again. The adjustment includes linear movement along the first direction a and / or the second direction b and / or rotation around the first direction a and / or the second direction b, until the light irradiation point in the first image coincides with the point to be measured. At this time, the processor calculates the mapping relationship between the two virtual coordinate systems according to the coordinate value of the light source 1 in the second virtual coordinate system and the coordinate value of the point to be measured in the first virtual coordinate system. For example: the coordinate value of the point to be measured in the first coordinate system is (0, 0), the irradiation point of the light source 1 coincides with it in the first image, and the coordinate value of the light source 1 in the second virtual coordinate system is (2, 1). Then the mapping relationship between the second virtual coordinate system and the first virtual coordinate system is the horizontal coordinate +1 and the vertical coordinate +1. The same is true when there is an angle mapping, which will not be repeated here. After the mapping relationship is clear, the processor can control the movement rules of the light source 1 in the second virtual coordinate system corresponding to other points to be measured. Of course, the above process can also be completed through any other point in the test area that is not a point to be measured. In this process, the processor can filter, adjust the grayscale, and binarize the first image, and identify the position and coordinate value of the light source 1 in the first virtual coordinate system by comparing the grayscale of the light point irradiated by the light source 1 in the test area with other positions. In this process, the linear motion of the light source 1 can be achieved by the processor through a driving motor, and the flipping and rotational motion of the light source 1 can be achieved by the processor through an electric rotating table and an electric pitch table.

[0087] It is understandable that, since different types of glasses to be tested are different, their refraction and emission degrees for light are also different, so step 102 needs to be calibrated in real time and multiple times during the testing process.

[0088] 103. Control the second image acquisition device 4 to follow the light source 1 to acquire the second image of the test area, and calculate the secondary image deviation value of the test glass according to the primary image and the secondary image generated at the corresponding test point on the second image.

[0089] Specifically, in order to improve the detection rate and accuracy, in this embodiment, the second image acquisition device 4 is controlled to move synchronously with the light source 1. In this embodiment, a third carrier 6 can be set corresponding to the second image acquisition device 4. The third carrier 6 is the installation structure of the second image acquisition device 4. It is a rigid structure, which can be a frame structure, a platform structure, a table structure, etc. The second image acquisition device 4 can be movably set thereon by a sliding member; the second image acquisition device 4 can be but is not limited to a telescope camera. The synchronous following of the light source 1 and the second image acquisition device 4 can be achieved by the processor controlling the driving parts of the two, as long as the optical axis of the light source 1 is coaxial with the optical axis of the second image acquisition device 4. For example: if the light source 1 moves 1 cm along the first direction a, the second image acquisition device 4 moves 1 cm along the first direction a in the same direction as the light source 1, and the same applies to other directions; for another example: the light source 1 flips upward 20 degrees around the first direction a. 0 , the distance between the light source 1 and the second image acquisition device 4 in the third direction c must be d, and the third direction c is the direction in which the light source 1, the first carrier 5 and the second image acquisition device 5 are arranged in sequence, then the second image acquisition device 4 needs to move upward along the second direction b by e=d*tan20 0 , and then control the second image acquisition device 4 to turn downward 70 degrees around the first direction a 0 , then the optical axis of the light source 1 is coaxial with the optical axis of the second image acquisition device 4; the second image acquisition device 4 and the light source 1 follow-up greatly improve the detection rate, and can synchronously locate and acquire the main image and the secondary image corresponding to the point to be measured, avoiding secondary positioning to acquire the main image and the secondary image, and ensuring the accuracy of positioning and acquisition. After the processor acquires the second image through the second image acquisition device 4, it calculates the secondary image deviation value according to the following formula

[0090] θ=atan(np / f)

[0091] Wherein: θ is the deviation angle between the primary image and the secondary image; h is the distance between the primary image and the secondary image in the second image, p is the pixel distance of the second image acquisition device; n is the ratio of h to p; f is the focal length of the second image acquisition device; this calculation method can be easily understood by those skilled in the art and will not be elaborated on here.

[0092] Further, see Attachment Fig.11 In a specific implementation, the measuring method of the secondary image deviation value measuring device provided in this embodiment further includes calibrating the light source 1 and the second image acquisition device 4 before step 101, so that the optical axes of the light source 1 and the second image acquisition device 4 are coaxial.

[0093] Specifically, the light source 1 and the second image acquisition device 4 are respectively arranged on the second carrier 5 and the third carrier 6. Because there may be a problem of incomplete alignment, in order to ensure the synchronous follow-up of the light source 1 and the second image acquisition device 4 and realize high-speed and high-precision detection, in this embodiment, a calibration step is performed before the formal detection to calibrate the position follow-up control rules of the light source 1 and the second image acquisition device 4. It can be understood that the glass 2 to be tested is not loaded during this process; the specific calibration includes the following steps:

[0094] 1011. Control the movement of the light source 1, which at least includes moving along a first direction a and a second direction b and flipping around the first direction a and the second direction b;

[0095] 1012. Control the second image acquisition device 4 to follow the light source 1, and control the third image acquisition device 7 to acquire a third image irradiated by the light source 1 on the second image acquisition device 4;

[0096] Specifically, the third image acquisition device 7 can be but is not limited to a camera. The third image acquisition device 7 is arranged on the same side of the second image acquisition device 4, and the third image acquisition device 7 can move at the same time as the second image acquisition device 4. The purpose of setting the third image acquisition device 7 in this embodiment is to obtain the third image containing the lens when the light source 1 illuminates the lens of the second image acquisition device 4. The processor controls the start and stop of the third image acquisition device 7 so that it can obtain the third image of the second image acquisition device 4 in real time. It can be understood that in this embodiment, the third image acquisition device 7 can be enabled only before the formal detection and can be turned off after the calibration is completed, or it can be enabled throughout the process.

[0097] 1013. Acquire a fourth image in the field of view of the second image acquisition device 4;

[0098] Specifically, the image generated in the second image acquisition device 4 when the detection light is irradiated to the lens of the second image acquisition device 4 is acquired.

[0099] 1014. Adjust the position of the light source 1 and / or the second image acquisition device 4 according to the third image and the fourth image, so that when the light source 1 is irradiated at the center of the lens of the second image acquisition device 4, the light source 1 is irradiated at the center of the fourth image, and determine the tracking deviation of the light source 1 and the second image acquisition device 4;

[0100] Specifically, the processor processes the third image and the fourth image to determine whether the detection light corresponding to the light source 1 in the second image is located at the center of the second image when the light source 1 is irradiated at the center of the lens of the second image acquisition device 4. In this process, a third virtual coordinate system can be established in the processor corresponding to the second image acquisition device 4, and a fourth virtual coordinate system can be established corresponding to the third image acquisition device 7. The tracking deviation between the light source 1 and the second image acquisition device 4 is determined based on the coordinate value of the light source 1 in the third image when the light source 1 is irradiated at the center of the lens of the second image acquisition device 4 and the coordinate value of the detection light of the light source 1 in the fourth image when it is located at the center of the fourth image. In subsequent formal retrieval, the movement of the light source 1 and the second image acquisition device 4 is driven according to the tracking deviation. For example: Moving the light source 1 generates (x 11 ,y 11 ) coordinate value, manually adjust the position of the second image acquisition device 4 to generate (x 22 ,y 22 ) or (x 22 ,y 22 , rotation θ, pitch β) coordinate values ​​to ensure that the optical axes of the two are coaxial. At this time, the light source 1 illuminates the center of the lens of the second image acquisition device 4 in the third image. The detection light of the light source 1 is observed in the center of the field of view in the fourth image. The tracking deviation between the light source 1 and the second image acquisition device 4 is (x 22 -x 11 ,y 22 -y 11 , rotation θ, pitch β), and the same is true for other directions. The calculation program can be implemented by the processor through program editing and multiple learning, which can be easily understood by those skilled in the art and will not be described in detail here. It can be understood that the image processing process in the above process is the same as the aforementioned processing process for the second image, and will not be described in detail here.
