Description

Technical fields:

[0001] This utility model relates to the field of camera testing technology, and specifically to a novel 360-degree camera splicing performance testing mechanism. Background technology:

[0002] With technological advancements, the automation and intelligence of camera stitching testing are continuously improving. To meet the demands for high precision and stability, camera stitching technology is constantly being optimized. Through precise camera calibration and image processing algorithms, issues such as lens distortion, lighting differences, and motion blur can be effectively eliminated, ensuring the accuracy of the stitching results.

[0003] Currently, conventional light source panels on the market have seams, which can easily lead to testing errors and affect accuracy. Therefore, some researchers have introduced a seamless light source panel. For example, Chinese utility model patent application CN 207779666 U discloses a testing machine that includes a testing machine body and a seamless light source panel. The testing machine body is used to place the camera module and testing fixtures, while the seamless light source panel is used to place the test drawing. When using this testing machine to perform SFR testing on the camera module, it can avoid the problem of the value frame on the test drawing corresponding to the seam, which would otherwise lead to errors in the test results.

[0004] However, this existing testing equipment still has the following shortcomings:

[0005] In this technical solution, the distance between the light source panel and the camera module is fixed. This means that the camera module can only be calibrated at a certain distance. This method is only suitable for testing small camera modules. It is difficult to test camera modules that are larger and heavier and need to take pictures at multiple distances.

[0006] In view of the above, the inventors propose the following technical solution. Utility model content:

[0023] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0024] See Figures 1 to 5 As shown, a novel 360-degree camera splicing performance testing mechanism includes: a base plate 1, on which a first chart module 11, a second chart module 12, and a third chart module 13 are spaced apart; and a testing module 2, which is disposed on the base plate 1 and used to clamp the camera for testing; wherein, the first chart module 11 has a first chart 110 slidably disposed for camera image capture testing; the second chart module 12 has a second chart 120 slidably disposed for camera image capture testing; and the third chart module 13 has a third chart 130 slidably disposed for camera image capture testing.

[0025] In this invention, a test module 2 clamps the camera to be tested. A first chart 110, a second chart 120, and a third chart 130 are sequentially arranged on the base plate 1 from near to far, corresponding to near, medium, and far distance tests, effectively enriching the testing levels and making it suitable for testing cameras of various sizes, thus improving applicability. Furthermore, compared to existing structures, in this invention, the first chart 110, the second chart 120, and the third chart 130 can all slide relative to the test module 2, which facilitates the camera on the test module 2 to capture images from different angles and distances, enabling comprehensive testing of stitching performance.

[0026] In this embodiment, the camera being tested is a quad-camera module. This invention uses a test module 2 to clamp the camera, enabling it to be raised, lowered, and rotated, effectively improving testing flexibility. Specifically, the test module 2 includes a test bracket 21 fixed to the base plate 1, a test lifting module 22 mounted on the test bracket 21, a test rotary motor 23 mounted on the test lifting module 22, a first fixing clamp 24 mounted on the test rotary motor 23 for fixing the camera, and a second fixing clamp 25 mounted on the first fixing clamp 24 for clamping and fixing the camera. The base plate 1 has a clearance hole 101 for the test lifting module 22 to move up and down. The test lifting module 22 is a vertically mounted linear motor; during lifting, its lower end extends downwards through the clearance hole 101 to increase the lifting stroke.

[0027] In this invention, the first chart 110 can move along the X, Y, and Z axes, which is more conducive to the camera's stitching performance testing and can effectively measure stitching errors, distortions, etc. Specifically, the first chart module 11 includes a first X-axis module 111 disposed on the base plate 1, a first slide rail 112 disposed beside the first X-axis module 111, a first Y-axis module 113 driven by the first X-axis module 111 and capable of sliding back and forth along the first slide rail 112, a first Z-axis module 114 slidably disposed on the first Y-axis module 113, a first chart 110 that can be raised and lowered disposed on the first Z-axis module 114, and a first pulley 115 disposed below the first Y-axis module 113 for sliding support. The first X-axis module 111 is a linear motor horizontally mounted on the base plate 1. The first X-axis module 111 works with the first pulley 115 to drive the first Y-axis module 113 to move, thereby adjusting the distance between the first chart 110 and the camera. The first Y-axis module 113 can adjust the angle between the first chart 110 and the camera. The first Z-axis module 114 adjusts the height of the first chart 110.

[0028] The second chart 120 can also move along the X, Y, and Z axes, which is more conducive to the camera's stitching performance testing and can effectively measure stitching errors, distortions, etc. Specifically, the second chart module 12 includes a second X-axis module 121 disposed on the base plate 1, a second slide rail 122 disposed next to the second X-axis module 121, a second Y-axis module 123 driven by the second X-axis module 121 and slidable back and forth along the second slide rail 122, a second Z-axis module 124 slidably disposed on the second Y-axis module 123, a second chart 120 disposed on the second Z-axis module 124 that can be raised and lowered, and a second pulley 125 disposed below the second Y-axis module 123 for sliding support. The second X-axis module 121 is a linear motor horizontally mounted on the base plate 1. The second X-axis module 121 and the second pulley 125 work together to drive the second Y-axis module 123 to move, thereby adjusting the distance between the second chart 120 and the camera. The second Y-axis module 123 can adjust the angle between the second chart 120 and the camera. The second Z-axis module 124 adjusts the height of the second chart 120.

[0029] This invention aims to simultaneously support the acquisition of three charts: small (near), medium, and large (far). To prevent the first chart 110 and the second chart 120 from obstructing the testing of the third chart 130, the first and second charts 110 are designed to be oscillating. Specifically, the first Z-axis module 114 is further equipped with a first oscillation module 15 for driving the first chart 110 to oscillate. The first oscillation module 15 includes a first oscillation frame 151 mounted on the first Z-axis module 114 and a first oscillation motor 152 mounted on one side of the first oscillation frame 151 for driving the first chart 110 to oscillate. The second chart 120 is larger than the first chart 110. The second Z-axis module 124 is further equipped with a second swing module 16 for driving the second chart 120 to swing. The second swing module 16 includes a second swing frame 161 mounted on the second Z-axis module 124 and a second swing motor 162 mounted on one side of the second swing frame 161 for driving the second chart 120 to swing. Here, when testing the second chart 120, the first chart 110 in front of it can be swung downwards to avoid obstruction; similarly, when testing the third chart 130, both the first chart 110 and the second chart 120 in front of it can be swung downwards to avoid obstruction.

[0030] In this invention, the third chart 130 can also move along the X, Y, and Z axes, which is more conducive to the camera's stitching performance testing and can effectively measure stitching errors, distortions, etc. Specifically, the third chart module 13 includes a third X-axis module 131 disposed on the base plate 1, a third slide rail 132 disposed beside the third X-axis module 131, a third Y-axis module 133 driven by the third X-axis module 131 and capable of sliding back and forth along the third slide rail 132, a third Z-axis module 134 slidably disposed on the third Y-axis module 133, and a third chart 130 that can be raised and lowered on the third Z-axis module 134.

[0031] The third chart 130 is larger than the second chart 120.

[0032] The base plate 1 is assembled from several splicing plates 102; the base plate 1 is detachably provided with multiple supporting feet 103; the base plate 1 is detachably provided with multiple sliding wheels 104.

[0033] In summary, this invention employs a test module 2 to hold the camera under test. By sequentially arranging a first chart 110, a second chart 120, and a third chart 130 on the base plate 1 from near to far, corresponding to near, medium, and far distance tests respectively, it effectively enriches the testing hierarchy, making it suitable for testing cameras of various sizes and improving applicability. Furthermore, compared to existing structures, in this invention, the first chart 110, the second chart 120, and the third chart 130 can all slide relative to the test module 2, which facilitates image acquisition by the camera on the test module 2 at different angles and distances, enabling comprehensive testing of stitching performance.
