[0055] In order to better understand the technical scheme and advantages of the present application, the content of the present application will be further described in detail below in combination with the drawings and specific embodiments. However, the specific embodiments described herein are only used to explain the present application and do not limit the present application. In addition, the technical features involved in each embodiment of the present application described below can be combined for use, except for the case of conflict, thereby constituting other embodiments within the scope of the present application.

[0056] The content described below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to numbers and / or letters in different examples, and such repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed.

[0057] Figure 1 The side view of the test device according to an embodiment of the present application is shown.Figure 2 A perspective view of the testing device is shown. As Figure 1 and Figure 2 shown, the testing device 100 for the binocular camera module can include a loading part 110, a first testing part 120, a second testing part 130, and a driving part 140. The loading part 110 is used to load the binocular camera module 200 to be tested. The first testing part 120 and the second testing part 130 are respectively used to test different performances of the binocular camera module 200. For example, when the loading part 110 loads the binocular camera module 200 at the first testing station, the first testing part 120 can test the first performance thereof; and when the binocular camera module 200 is at the second testing station, the second testing part 130 can test the second performance thereof.

[0058] The driving part 140 can drive the loading part 110 to move to the first testing station corresponding to the first testing part 120, and also can drive the loading part 110 to move to the second testing station corresponding to the second testing part 130, so as to realize the positioning of the binocular camera module 200 at different testing stations. As Figure 1 and Figure 2 shown, the driving part 140 can be a linear motor which controls the moving position of the loading part 110 through a guide rail, so as to position the binocular camera module 200. However, the present application is not limited thereto, and the driving part 140 can also drive the loading part 110 in other ways.

[0059] Therefore, the loading part and the binocular camera module loaded thereon can be controlled by the driving part to move to the position required by different testing items, so as to perform corresponding tests, thereby realizing the integration of the testing functions for different performances of the binocular camera module in the same testing device. Therefore, the testing process of the binocular camera module can be simplified, the efficiency can be improved, and the cost can be reduced.

[0060] Figure 3 A perspective view of the face light source plate according to another embodiment of the present application is shown; Figure 4 A side view of the testing device according to another embodiment of the present application is shown. In order to clearly show the cooperation of the loading part 110 and the binocular camera module 200 loaded thereon at the first testing station with the first testing part 120, some structural members for supporting the first testing part 120 are omitted in Figure 4 According to this embodiment, the first testing part 120 can include a face light source plate as Figure 3 shown, and in Figure 1 , Figure 2 , Figure 4 the light emitting surface of the face light source plate faces downward, i.e. the light emitting direction thereof is toward the first testing station. Therefore, the performances of the binocular camera module 200 such as the brightness uniformity, the dirt degree, the noise ratio, etc. can be tested by the face light source plate.

[0061] According to one embodiment, the surface light source plate is a surface light source plate with adjustable color temperature and brightness, which can emit uniform white light and has an illumination of 550±50 LUX, a color temperature of 5000±200 k, and a uniformity of more than 92%. Thus, the brightness uniformity, dirt level, and noise ratio of the binocular camera module can be tested.

[0062] Referring to Figure 4 , the loading part 110 can be a loading table that facilitates loading of the binocular camera module 200 to be tested. When it is necessary to test the performance of the binocular camera module 200 using the first testing part 120, the driving part 140 can drive the loading table with the binocular camera module 200 to move to the first testing station corresponding to the first testing part 120, for example, the first testing station shown in Figure 4 directly below the first testing part 120. When the loading table and the binocular camera module 200 are moved into position, the distance between the binocular camera module 200 and the surface light source plate is 1-2 cm, so that the surface light source plate can cover the entire field of view of the binocular camera module 200.

[0063] Figure 5 A photo taken by the binocular camera module to be tested at the first testing station toward the first testing part is shown. When the binocular camera module is tested using the first testing part, the loading part with the binocular camera module is driven to the first testing station by the driving part, so that the binocular camera module to be tested is aligned with the first testing part, and then the binocular camera module images and the photo shown in Figure 5 is obtained. According to the photo, the brightness uniformity, dirt level, and noise ratio of the binocular camera module can be calculated in the background.

[0064] Referring again to Figure 1 and Figure 2 , the second testing part 130 can include a planar backlight plate 131 and a test chart 132. The planar backlight plate 131 emits light toward the second testing station, and the test chart 132 is fixed between the planar backlight plate 131 and the second testing station, so that when the planar backlight plate 131 is turned on, the binocular camera module can be tested using the test chart 132. The performance tested at the second testing station can include resolution, gray scale resolution, color restoration, etc.

[0065] According to one embodiment, the second testing part 130 can further include a distance adjusting mechanism 133. The distance adjusting mechanism 133 is connected to the test chart 132 to adjust the distance between the test chart 132 and the binocular camera module 200 to be tested located at the second testing station. In Figure 1 and Figure 2In the illustrated embodiment, the test pattern 132 and the flat backlight panel 131 are closely fitted together so that they move together during adjustment, but this application is not limited to this. The test pattern 132 and the flat backlight panel 131 can also be set independently of each other.

[0066] exist Figure 1 and Figure 2 In the illustrated embodiment, the distance adjustment mechanism is a mechanism that adjusts the height of the test chart by adjusting a joystick, but this application is not limited to this. Any mechanism capable of adjusting the distance between the test chart and the binocular camera module is applicable.

[0067] On the other hand, the loading unit 110 may also have a lifting mechanism (not shown in the figure), through which the height of the binocular camera module to be tested can be adjusted, thereby changing its distance from the first test unit at the first test station and its distance from the test chart of the second test unit at the second test station.

[0068] According to one embodiment, the planar backlight panel 131 can emit uniform white light and has an illuminance of 550±50 LUX, a color temperature of 5000±200 K, and a uniformity of over 92%. This facilitates the testing of the performance of the binocular camera module.

[0069] Figure 6 A schematic layout diagram of a test chart according to one embodiment of this application is shown. Figure 6 As shown, the test pattern 132 may include a black and white striped patchwork pattern 132a (see...). Figure 6a The black and white striped pattern 132a can be distributed in the central area, edge area, and area between the central and edge areas of the test chart 132 to facilitate testing the resolution of the binocular camera module 200 under test at different field of view angles. For example, when the test chart 132 and the binocular camera module 200 under test are in appropriate relative positions, the aforementioned distribution of the black and white striped pattern 132a on the test chart 132 can be used to test the resolution of the binocular camera module 200 at 70%, 30%, and 0% field of view angles.

[0070] Moreover, since the black and white stripe splicing pattern 132a is distributed in different positions of the test chart 132, the resolving power of the binocular camera module 200 at different field angles can be further tested by adjusting the distance between the test chart 132 and the binocular camera module 200 to be tested. For example, as described above, the resolving power of the binocular camera module 200 at 70% field angle, 30% field angle and 0% field angle can be tested when the test chart 132 and the binocular camera module 200 to be tested are at a certain relative position. Then, by adjusting the distance between the test chart 132 and the binocular camera module 200 to be tested, the resolving power of the binocular camera module 200 at other three different field angles, such as 80% field angle, 35% field angle and 0% field angle, can be tested.

[0071] According to an embodiment, the size of the black and white stripe splicing pattern can be set according to actual needs, for example, the width of a single black and white stripe can be 0.5-2 mm (such as 1 mm), and the length can be 5-20 mm (such as 10 mm).

[0072] Referring back to Figure 6 , the test chart 132 can further include a gray scale test bar 132b (see Figure 6b ). The gray scale test bar 132b can include gray color blocks with different gray scale values, so as to test the gray scale resolution of the binocular camera module 200 to be tested. After the binocular camera module 200 to be tested takes an image of the gray scale test bar 132b, the gray scale resolution can be tested by comparing the difference between the previous gray scale brightness and the next gray scale brightness.

[0073] According to an embodiment, the size and position of the gray scale test bar in the test chart can be set according to actual needs, for example, the width of each color block in the gray scale test bar can be 20-60 mm (such as 40 mm), and the gray scale test bar can be located at any appropriate position in the test chart, for example, in the middle or at the lower part, and 10-40 mm (such as 25 mm) away from the lower edge of the test chart.

[0074] Referring back to Figure 6 , the test chart 132 can further include a color test bar 132c (see Figure 6c ). The color test bar 132c can include color blocks with different colors (such as pink, purple, blue, green, yellow, red and black), so as to test the color restoration capability of the binocular camera module 200 to be tested. After the binocular camera module 200 to be tested takes an image of the color test bar 132c, the color restoration capability can be tested by comparing the different color blocks in the generated image with the standard color plate.

[0075] According to an embodiment, the size of the color test strip and the position in the test chart can be set according to actual needs, for example, the width of each color block in the color test strip can be 20-60 mm (such as 40 mm), and the color test strip can be located at any appropriate position in the test chart, for example, in the middle upper part, and 10-40 mm (such as 25 mm) away from the lower edge of the test chart.

[0076] Referring again to Figure 6 , the test chart 132 can further include a positioning pattern 132d (see Figure 6d ). The positioning pattern 132d is distributed at positions symmetrical with respect to the center point of the test chart 132, so as to position the relative positions of the binocular camera module 200 to be tested and the test chart 132.

[0077] As shown in Figure 6d , the positioning pattern 132d can include four corner point combinations, which are respectively located at the X, Y symmetrical positions with the center point of the test chart 132 as the coordinate origin.

[0078] Referring again to Figure 2 , the test device 100 can further include a light source 150, the light source 150 has a different color temperature from the planar backlight panel 131, and the light emitting direction of the light source 150 is towards the test chart 132, so that when the planar backlight panel 131 and / or the light source 150 is turned on, the color reproduction capability of the binocular camera module 200 to be tested can be tested under different color temperatures.

[0079] For example, the light source 150 can be a warm light lamp, which can have a color temperature different from that of the planar backlight panel 131, for example, 2700k. During the test, the color reproduction capability of the binocular camera module 200 under different color temperatures can be tested by controlling the turning on and off of the light source 150.

[0080] According to an embodiment, the test device 100 can further include an encapsulation shell (not shown in the figure), which can encapsulate the loading part 110, the first test part 120, the second test part 130, and the driving part 140 therein to prevent external light from interfering with the performance test.

[0081] Figure 7 An effect diagram of the binocular camera module imaging under the condition of a white light source of 5000k is shown; Figure 8 An effect diagram of the binocular camera module imaging under the condition of a warm light source of 2700k is shown.

[0082] Figure 9 A flowchart of a method for testing a binocular camera module by using the above test device according to an embodiment of the present application is shown. As Figure 9As shown, the method 300 can include steps 310, 320, 330, 340. In step S310, the loading part loaded with the binocular camera module to be tested is driven by the driving part to move the binocular camera module to be tested to the first test station. Then, in step S320, the first performance of the binocular camera module to be tested is tested by the first test part at the first test station.

[0083] In step S330, the loading part loaded with the binocular camera module to be tested is driven by the driving part to move the binocular camera module to be tested to the second test station. Then, in step S340, the second performance of the binocular camera module to be tested is tested by the second test part at the second test station.

[0084] Thus, the loading part and the binocular camera module loaded thereon can be controlled by the driving part to move to the positions required by different test items to perform corresponding tests, so that the test functions for different performances of the binocular camera module are realized in the same test device. Therefore, the test process of the binocular camera module can be simplified, the efficiency is improved, and the cost is reduced.

[0085] It can be understood that the order of steps S310-S320 and steps S330-S340 can be adjusted according to actual needs, so that the required test work is completed at the corresponding test station first.

As shown, Figure 10 In addition to steps 310, 320, 330, 340, between steps S310 and S320, the method 300' can also include step S315. In step S315, when the binocular camera module to be tested moves to the first test station, the distance between the binocular camera module to be tested and the first test part is adjusted to 1-2 cm, so that the first test part covers the field of view angle of the binocular camera module to be tested.

In step S335, when the binocular camera module to be tested moves to the second test station, the distance between the binocular camera module to be tested and the second test part is adjusted to test the resolving power of the binocular camera module to be tested at different field of view angles.

[0088] According to an embodiment, in the step S340, the light sources with different color temperatures can be turned on to test the color restoration capability of the binocular camera module to be tested by the second test unit under different color temperatures.
