Description

Technical Field

[0001] The utility model relates to the technical field of splicing camera testing equipment, in particular to a testing tool. Background Art

[0002] Stitching cameras use two or more lenses to capture and fuse images, increasing the field of view and enabling panoramic monitoring. These cameras are designed for complex use cases, operating in ambient temperatures between -40°C and 70°C. Due to the expansion coefficients of lens modules and related components, temperature fluctuations significantly impact image stitching, leading to vertical misalignment or left-right scaling at the stitched joints. Image stitching for these cameras is typically performed before shipment, without temperature compensation. Current stitching algorithms are incapable of adaptive stitching. Therefore, testing in high and low temperature environments is necessary to mitigate these risks.

[0003] Currently, relevant high and low temperature environment tests are completed in an incubator. During high and low temperature tests, the incubator door needs to be opened and closed multiple times, which has a certain impact on the life of the incubator and increases the maintenance cost of the incubator. During high temperature testing, the operator needs to manually open the incubator door and manually rotate the device under test so that the splicing seam area or the four corners of the image are in the center of the test chart before testing. After the test is completed, it is manually rotated to the next area until all splicing seams and the four corners of the image are traversed. During this period, the high incubator temperature can easily cause harm to the operator. During low temperature testing, when the incubator door is opened, the window glass of the incubator will fog and frost, affecting the image test. Therefore, after each test, it is necessary to first heat it up to room temperature, adjust the equipment position, and then cool it down for testing. The heating and cooling time is relatively long.

[0004] Therefore, when conducting high and low temperature tests on splicing cameras, how to improve test safety, reduce test time, reduce labor costs, and reduce temperature chamber maintenance costs is an issue that the industry urgently needs to solve. Utility Model Content

Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them.

[0047] When testing in high and low temperature environments, it's important to pay attention not only to the stitching effect of the camera's stitching image, but also to the vignetting of the image. When testing in high and low temperature environments, the camera needs to be placed in an incubator for image testing. The test requires viewing through the incubator's glass door. While the camera's field of view is wide, even up to 360°, the incubator's glass door's field of view is limited to approximately 90°. The camera's fixed lens generally cannot rotate axially, so the lens needs to be manually rotated during testing to ensure the image stitching seam falls on the test drawing. This manual opening and closing of the incubator's glass door and manual rotation of the camera reduce the incubator's service life and increase maintenance costs. High-temperature testing can easily lead to burns to the tester, while low-temperature testing can result in longer test times.

[0048] In order to solve the above problems, the present invention provides a test tool. Figures 1 to 4 The structure and working principle of the test tool of the present utility model are described in detail.

[0049] like Figures 1 to 3 As shown, the present invention provides a test fixture. The test fixture includes an adjustment bracket 100, which includes a mounting component 110 and a second driving component 120. The mounting component 110 is configured to be installed within an incubator 400 and is also configured to connect to a splicing camera 500. The second driving component 120 is mounted on the mounting component 110. The driving end of the second driving component 120 is configured to connect to the splicing camera 500 and drive the splicing camera 500 to rotate about its own axis so that the splicing seam between two adjacent fixed-point lenses in the splicing camera 500 faces the window glass 420 of the incubator 400.

[0050] In this embodiment, the installation component 110 allows the adjustment bracket 100 to be installed within the incubator 400. Furthermore, it provides a mounting base for the spliced ​​camera 500, allowing the spliced ​​camera 500 to be positioned within the incubator 400, thereby facilitating the incubator 400 creating a test environment with varying temperatures. By providing a second drive component 120 connected to the spliced ​​camera 500 within the installation component 110, the second drive component 120 can be used to drive the spliced ​​camera 500 to rotate about its own axis. This prevents testers from manually opening and closing the door 410 of the incubator 400, thus avoiding frequent opening and closing of the door 410. This reduces human resource costs, reduces maintenance costs for the incubator 400, and increases the service life of the incubator. This also prevents burns to testers during high-temperature testing. During low-temperature testing, there is no need to first raise each area to room temperature, adjust the equipment position, and then cool it down for testing, thus shortening the low-temperature testing time. The present invention solves the problems in the prior art of high and low temperature testing of splicing cameras, such as high temperature easily scalding testers, long low temperature testing time, high manpower input cost, and high temperature box maintenance cost.

[0051] Preferably, the driving end of the second driving component 120 is connected to the stitching camera 500 to drive the stitching camera 500 to rotate about its own axis so that the stitching seam between two adjacent fixed-point lenses in the stitching camera 500 faces the window glass 420 of the incubator 400. This design facilitates the determination of the coordinates of the stitching seam viewpoint A.

[0052] like Figure 2 As shown, in some embodiments, the mounting component 110 includes a turntable 111; the turntable 111 has a hollow area in the middle, which can reduce the overall weight of the adjustment bracket 100, avoid the second driving component 120 from bearing excessive weight, and enable the second driving component 120 to drive the stitching camera 500 with a small torque.

[0053] Furthermore, a reinforcing rod 112 is installed in the hollow area of ​​the turntable 111 to improve the strength of the turntable 111. The mounting end of the second driving component 120 can be mounted on the reinforcing rod 112.

[0054] Furthermore, a connecting rod 113 is provided on the lower side of the turntable 111 ; the lower end of the connecting rod 113 is connected to the stitching camera 500 .

[0055] It is understood that the turntable 111 can be in the shape of a ring or a polygon. Preferably, the turntable 111 is in the shape of a ring or a regular polygon. The plurality of stitching cameras 500 are evenly arranged around the circumference of the turntable 111.

[0056] In some embodiments, the second driving component 120 is coaxially disposed with the corresponding stitching camera 500. In other words, the rotational axis of the second driving component 120 coincides with the central axis of the corresponding stitching camera 500. Specifically, the lower end of the second driving component 120 is connected to the stitching camera 500, and the upper end of the second driving component 120 is connected to the connecting rod 113.

[0057] In some other embodiments, the second driving component 120 includes a second driving member 121 and a second transmission member 122. The mounting end of the second driving member 121 is connected to the mounting component 110. The second transmission member 122 extends radially of the mounting component 110 and is located between the second driving member 121 and the stitched camera 500. The driving end of the second driving member 121 is connected to the stitched camera 500 via the second transmission member 122, and is configured to drive the stitched camera 500 to rotate about its own axis. Specifically, the upper end of the second driving member 121 is connected to the reinforcing rod 112, and the lower end of the second driving member 121 is connected to the corresponding stitched camera 500 via the second transmission member 122, and is configured to drive the corresponding stitched camera 500 to rotate about its own axis. In this embodiment, the rotational central axis of the second driving member 121 does not coincide with the central axis of the corresponding stitching camera 500. The second driving member 121 drives the stitching camera 500 to rotate around its own axis through the second transmission member 122, which can prevent the second driving member 121 from bearing excessive weight. A second driving member 121 with a small torque can be used to drive the stitching camera 500, thereby reducing the purchase cost of the second driving member 121.

[0058] Furthermore, the second drive member 121 includes a second motor; the second transmission member 122 includes a transmission chain, a driving gear, and a driven gear. The driving gear is coaxially connected to the drive end of the second motor, and the driven gear is coaxially connected to the corresponding stitching camera 500. The transmission chain extends radially along the turntable 111, with one end of the transmission chain meshing with the driving gear and the other end meshing with the driven gear. The rotation of the second motor drives the driving gear, which in turn drives the driven gear through the transmission chain, thereby driving the corresponding stitching camera 500 to rotate about its own axis.

[0059] In some embodiments, the mounting component 110 can be used to mount a stitching camera 500. The second driving component 120 drives the stitching camera 500 to rotate around its own axis. Specifically, the turntable 111 can be used to mount a stitching camera 500.

[0060] In other embodiments, the mounting assembly 110 can be configured to connect to multiple stitching cameras 500, with the multiple stitching cameras 500 spaced apart circumferentially around the mounting assembly 110. The adjustment bracket 100 includes a first drive assembly 130 and multiple second drive assemblies 120. The multiple second drive assemblies 120 are connected to the stitching cameras 500 in a one-to-one correspondence. The first drive assembly 130 is configured to be mounted on the incubator 400 and connected to the mounting assembly 110. The first drive assembly 130, through the mounting assembly 110, drives all stitching cameras 500 to rotate axially around the mounting assembly 110, bringing one stitching camera 500 closer to the window glass 420. In this embodiment, by arranging multiple stitching cameras 500 spaced apart circumferentially around the mounting assembly 110, multiple stitching cameras 500 can be tested, improving testing efficiency. By providing a first driving component 130 connected to the mounting component 110, the first driving component 130 can be used to drive the mounting component 110, thereby driving all the stitching cameras 500 to rotate around the axial direction of the mounting component 110, so that one stitching camera 500 is close to the window glass 420, preparing for completing the test of the stitching camera 500 close to the window glass 420.

[0061] The specific testing process may include: using the first driving component 130 to drive the mounting component 110, thereby causing all the stitched cameras 500 to rotate about the axis of the mounting component 110, so that the target stitched camera 500 to be tested is close to the window glass 420. Using the second driving component 120, the target stitched camera 500 to be tested is driven to rotate about its own axis, so that the stitching seam between two adjacent fixed-point lenses faces the window glass 420 of the incubator 400.

[0062] Furthermore, a plurality of connecting rods 113 are provided on the lower side of the turntable 111 ; the plurality of connecting rods 113 are spaced and evenly arranged around the circumference of the turntable 111 , and the lower ends of the plurality of connecting rods 113 are connected to the stitching cameras 500 in a one-to-one correspondence.

[0063] Furthermore, the first drive component 130 includes a first motor, which is mounted on the incubator 400 and is located below and connected to the turntable 111. The first motor drives the turntable 111 to rotate about its axis, thereby driving all of the stitching cameras 500 to rotate about the axis of the turntable 111, so that one of the stitching cameras 500 is close to the window glass 420.

[0064] Specifically, a plurality of reinforcing rods 112 are provided in the hollow area of ​​the turntable 111 , and the plurality of reinforcing rods 112 cross at the center of the turntable 111 . The first motor is located at the center of the turntable 111 and is connected to the reinforcing rods 112 .

[0065] In some embodiments, the adjustment bracket 100 further includes a third driving component 140. The third driving component 140 is mounted on the incubator 400. The driving end of the third driving component 140 is connected to the mounting component 110. The third driving component 140 drives the stitching camera 500 to move along its own axial direction through the mounting component 110. In other words, the third driving component 140 can drive the stitching camera 500 to move along its own axial direction. By providing the third driving component 140 connected to the mounting component 110, the third driving component 140 can be used to drive the stitching camera 500 to rise and fall along its own axial direction, thereby aligning the stitching seam viewpoint A with the center of the window glass 420.

[0066] In some embodiments, the adjustment bracket 100 further includes a base 150, which is mounted on the bottom plate of the incubator 400. The third driving component 140 is located below the mounting component 110, and the lower end of the third driving component 140 is connected to the base 150. The provision of the base 150 can increase the installation stability of the adjustment bracket 100.

[0067] Specifically, the lower end of the third drive component 140 is mounted to the bottom plate of the incubator 400 via the base 150. The upper end of the third drive component 140 is connected to the lower end of the first drive component 130. The upper end of the first drive component 130, i.e., the driving end of the first drive component 130, is located at the center of the turntable 111 and is connected to the reinforcing rod 112. The third drive component 140 drives all the stitching cameras 500 to rise and fall along the axis of the stitching cameras 500 themselves through the first drive component 130 and the turntable 111.

[0068] Exemplarily, the third driving component 140 includes an electric telescopic rod; the lower end of the electric telescopic rod, that is, the mounting end of the electric telescopic rod, is installed on the bottom plate of the incubator 400 through the base 150, and the upper end of the electric telescopic rod, that is, the driving end of the electric telescopic rod, is connected to the turntable 111 through the first driving component 130.

[0069] Illustratively, the third drive component 140 includes a third drive member 141 and a screw transmission structure 142. The third drive member 141 is mounted on the incubator 400. The screw transmission structure 142 is connected to the third drive member 141 and the mounting component 110. The third drive member 141 drives the mounting component 110 to move up and down along the axial direction of the stitching camera 500 through the screw transmission structure 142. Specifically, the screw transmission structure 142 includes a screw, a nut seat (not shown), and a limit rod (not shown). One end of the screw is connected to the driving end of the third drive member 141, and the other end extends axially along the stitching camera 500. The nut seat is threadedly assembled with the screw and connected to the first drive component 130. The limit rod is mounted on the incubator 400 and slides with the nut seat along the axial direction of the stitching camera 500. The third drive member 141 includes a third motor. This third motor drives the screw, which, under the limit of the limit rod, moves the nut seat up and down along the screw, thereby driving the turntable 111 and all the stitching cameras 500 to rise and fall along their own axis. Driven by the screw drive structure 142, the height can be infinitely adjusted.

[0070] Under varying ambient temperatures, temperature-induced structural deformation can cause image vignetting. Furthermore, for a stitching camera 500 with a fixed lens that features upper and lower field-of-view angle adjustment, thermal expansion and contraction can cause deformation of the lens module and support structure. When this deformation causes the image to exceed the effective area of ​​the test chart or causes structural obstruction of the lens's field of view, vignetting can occur. In this embodiment, the image can be restored to the effective area of ​​the test chart by operating the third drive member 141 to adjust the height of the stitching camera 500 relative to the window glass 420.

[0071] like Figure 1 As shown, in some embodiments, the test fixture further includes a test board 200 ; the test board 200 is used to be placed outside the temperature chamber 400 and facing the window glass 420 . The stitching camera 500 takes a picture of the test board 200 .

[0072] Furthermore, one side of the test board 200 may have a checkerboard test pattern, or / and the other side of the test board 200, facing away from the checkerboard test pattern, may be a whiteboard. When testing the stitching effect, the checkerboard test pattern can be oriented toward the window glass 420, with two adjacent fixed-point lenses of the stitching camera 500 capturing the checkerboard test pattern to facilitate viewing of the stitching effect of the stitching. When testing image vignetting, the whiteboard can be oriented toward the window glass 420, with two adjacent fixed-point lenses of the stitching camera 500 capturing the whiteboard to determine whether vignetting areas exist.

[0073] Furthermore, the test fixture includes a guide structure 300 ; the guide structure 300 is disposed outside the incubator 400 and slides with the test board 200 in a direction perpendicular to the window glass 420 . This provides direction for the movement of the test board 200 and improves the efficiency of adjusting the test board 200 .

[0074] Specifically, the guide structure 300 includes an upper guide rail 310 and a lower guide rail 320. The upper guide rail 310 is located above the test board 200 and slides with the upper end of the test board 200 in a direction perpendicular to the window glass 420. The lower guide rail 320 is located below the test board 200 and slides with the lower end of the test board 200 in a direction perpendicular to the window glass 420. The provision of the upper guide rail 310 and the lower guide rail 320 improves the movement stability of the test board 200.

[0075] Furthermore, the test fixture further includes a fourth driving component connected to the test board 200 and configured to drive the test board 200 to move along the guide structure 300, thereby further saving labor costs.

[0076] Specifically, the fourth driving component includes a linear motor.

[0077] like Figure 4 As shown, point A is the seam viewpoint. It should be noted that the seam viewpoint is the intersection of two sides of the field of view angles of two adjacent fixed-point lenses that are far away from each other. Figure 4 The stitching camera 500 includes eight fixed-point lenses, numbered 1 to 8. The field of view angle of fixed-point lens 1 is α, and the field of view angle of fixed-point lens 2 is β. The stitching seam viewpoint A is the intersection of two sides of the field of view angle α and the field of view angle β that are away from each other.

[0078] It should be noted that, in this embodiment, a plurality means at least two.

[0079] like Figure 3 As shown, the center of the bottom surface of the space in the incubator 400 is used as the coordinate origin, and the coordinates of the origin O are (x0, y0, z0); the central axis of the screw is used as the Z axis, and the direction perpendicular to the window glass 420 is used as the Y axis to establish a coordinate system. At this time, the coordinates of the splicing seam viewpoint A are (x1, y1, z1).

[0080] The following combination Figures 1 to 4 , the use process of the test tooling of the utility model is explained.

[0081] After the multiple stitching cameras 500 are installed, they are connected to the network and powered on, and the door 410 of the incubator 400 is closed.

[0082] The first driving component 130 is actuated to rotate the stitching camera 500 to a position close to the window glass 420 of the incubator 400 ; the second driving component 120 is actuated to make the stitching seam viewpoint A of two adjacent fixed-point lenses in the stitching camera 500 to face the window glass 420 .

[0083] The third driving component 140 operates to drive the stitching camera 500 up and down, so that the stitching seam viewpoint A moves to a position directly opposite the center of the window glass 420. During this adjustment process, the host computer can determine the displacement of the stitching seam viewpoint A based on the size of the stitching camera 500 and the coordinates of the stitching seam viewpoint A, thereby controlling the operation of the third driving component 140 to move the stitching seam viewpoint A to a position directly opposite the center of the window glass 420.

[0084] According to the splicing test distance, the test board 200 is moved to the test position along the Y direction manually or by the fourth driving component.

[0085] When testing the stitching effect, the checkerboard test pattern on the test board 200 is directed toward the window glass 420, and the fixed lens is used to capture the test board 200. After this is completed, the second driving component 120 is activated to reorient the stitching seam viewpoints of two adjacent fixed lens lenses toward the center of the window glass 420, until all fixed lens lenses have been captured.

[0086] During the vignetting test, the whiteboard of the test board 200 is oriented toward the window glass 420. For the stitching camera 500, whose fixed lens can be adjusted vertically, the fixed lens is adjusted to the upper or lower limit position. The image field of view at the limit position is analyzed to determine whether it falls on the whiteboard. If the image extends beyond the whiteboard, the third drive component 140 adjusts the height of the stitching camera 500, moving the camera 500 in the Z direction until the image falls on the whiteboard. After the test is completed, the second drive component 120 is used to reposition the viewpoint of the stitching seam between the other two adjacent fixed lenses to face the center position of the window glass 420, until all the fixed lenses have been tested.

[0087] By changing the temperature of the temperature box 400 , high and low temperature detection of the spliced ​​camera 500 can be performed at different temperatures.
