Description

Technical Field

[0001] This invention relates to the field of camera module technology, and in particular to multi-view cameras, multi-view camera adjustment devices, and multi-view camera assembly and adjustment methods. Background Technology

[0002] With the development of vision technology, vision-based intelligent driver assistance systems (ADAS) have been designed and developed. These systems possess capabilities such as distance measurement and recognition, and, in conjunction with cameras mounted on vehicles, can achieve functions such as blind spot detection, collision warning, and autonomous driving. Among these, the front-view camera is currently the most frequently used camera. Mainstream front-view cameras include monocular and multi-view cameras. Monocular cameras have a smaller field of view and lower distance measurement accuracy, while multi-view cameras have a larger field of view and higher distance measurement accuracy. However, multi-view cameras are more complex to calibrate, require more sophisticated equipment and personnel, and are more expensive.

[0003] In traditional multi-camera systems, each camera is pre-fixed with screws or other structural elements during calibration, making it impossible to adjust the forward / backward displacement, deflection angle, or tilt angle of a single camera individually. Therefore, during complex algorithm calibration, differences in the relative positions of the cameras can easily lead to difficulties or even failures in extrinsic parameter calibration at the client end, impacting subsequent autonomous driving algorithms for the entire vehicle. Summary of the Invention

[0004] Therefore, it is necessary to provide a multi-view camera to address the problem of calibration difficulties caused by the fixed structure of existing multi-view cameras.

[0006] Multiple cameras;

[0007] A bracket having multiple mounting holes into which multiple cameras are respectively inserted; and

[0008] Multiple elastic structural components are respectively disposed between the camera and the bracket.

[0009] During the assembly of the aforementioned multi-camera system, the elastic structural component can deform, allowing the camera to be rotated or moved for calibration. After calibration, the structure of the camera and the bracket is fixed, preventing subsequent creep that could lead to calibration failure.

[0018] An adjustment fixture is disposed above the support assembly and is used to grasp and drive the camera of the multi-view camera to rotate or move so that the calibration cursor of the camera image after being powered on is aligned with the calibration mark.

[0019] The aforementioned multi-camera adjustment device can calibrate the multi-camera during assembly, thereby simplifying the calibration steps and reducing the difficulty of calibrating the multi-camera.

[0020] In one embodiment, the adjustment fixture includes a handle and a limiting claw. The limiting claw includes a connecting arm fixed to the handle and a pair of positioning posts fixed to both ends of the connecting arm. The positioning posts are used to be inserted into the positioning holes of the camera mount of the camera.

[0021] In one embodiment, the limiting claw further includes a positioning block protruding from the outer surface of the positioning post, the positioning block being used to abut against the camera support ear.

[0022] In one embodiment, the support assembly includes a pair of support arms, a support platform fixed to the support arms, and a label platform slidably connected to the support arms, the support platform supporting the bracket, and the label mounted on the label platform.

[0023] Furthermore, the present invention provides a method for assembling a multi-view camera, for assembling a multi-view camera as described above, comprising the following steps:

[0024] The elastic structure is installed on the bracket of the multi-view camera, and a pair of cameras of the multi-view camera are respectively inserted into a pair of mounting holes of the bracket, so that the elastic structure is located between the bracket and the camera.

[0025] The bracket is placed on the support assembly of the multi-view camera adjustment device, and the camera is powered on so that the camera forms a calibration cursor;

[0026] By adjusting the fixture, the camera is grasped and rotated or moved so that the calibration cursor is aligned with the calibration mark on the calibration plate of the supporting component; and

[0027] Secure the camera to the bracket.

[0028] In one embodiment, the step of mounting the elastic structure to the bracket of the multi-view camera and inserting a pair of cameras of the multi-view camera into a pair of mounting holes in the bracket, so that the elastic structure is located between the bracket and the cameras, includes:

Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0048] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0052] Specifically, please refer to Figure 1 and Figure 3 This application provides a multi-view camera 10, which may include multiple cameras 11, a bracket 12, and multiple elastic structural members 13. After being powered on, each camera 11 can have its imaging center calculated by software based on the pixels of its image, forming a calibration cursor 111 at the imaging center. The bracket 12 has multiple mounting holes 121, the number of which corresponds to the number of cameras 11. Multiple cameras 11 are respectively inserted into the mounting holes 121. The elastic structural members 13 are respectively disposed between the cameras 11 and the bracket 12. It is understood that before fixing the cameras 11, they can be moved or rotated for calibration. The elastic structural members 13 can deform to support the cameras 11 during movement or rotation. After calibration, the cameras 11 are then fixedly connected to the bracket 12. In this way, the camera 11 is calibrated before it is fixed to the bracket 12. After calibration, the camera 11 and the bracket 12 are structurally fixed and will not cause subsequent creep that would lead to calibration failure.

[0053] More specifically, such as Figure 3As shown, in one embodiment, the bracket 12 includes a bracket body 122 and a plurality of fixing blocks 123 protruding from the bracket body 122. The fixing blocks 123 are respectively arranged on both sides of the mounting hole 121. The camera 11 includes a camera body 112 inserted into the mounting hole 121 and camera ears 113 protruding from both sides of the camera 11. The camera ears 113 are fixed to the fixing blocks 123 to fix the camera body 112 to the bracket body 122. With this configuration, when the camera ears 113 on both sides of the camera body 112 are grasped simultaneously, the camera ears 113 can smoothly drive the camera body 112 to move or rotate around the camera body 112, which facilitates the assembly personnel to quickly mark the camera body 112. The fixing block 123 corresponds to the camera bracket 113 and is respectively disposed on both sides of the mounting hole 121. After the camera body 112 is calibrated, there will be a certain offset between the camera body 112 and the bracket body 122, making it impossible to fix the camera body 112 to the bracket body 122 in the traditional way. Therefore, by fixing the camera bracket 113 to the fixing block 123, the problem of not being able to fix the camera 112 can be avoided. The elastic structural member 13 can be disposed between the camera body 112 and the bracket body 122 to support the camera body 112 during calibration; it can also be disposed between the fixing block 123 and the camera bracket 113 to support the camera bracket 113 during calibration.

[0054] Optionally, such as Figure 3 As shown, in one embodiment, the fixing block 123 has a limiting groove 1231, and the camera mount 113 is fixedly disposed within the limiting groove 1231. This arrangement serves two purposes: firstly, the limiting groove 1231 can restrict the movement and rotation range of the camera mount 113 and initially position the camera body 112, allowing the camera body 112 to be calibrated with only slight adjustments; secondly, after the camera body 112 is calibrated, the groove wall of the limiting groove 1231 can be used for fixed connection with the camera mount 113.

[0055] It is understandable that, in order for the camera mount 113 to move or rotate within the limiting groove 1231, such as Figure 6As shown, in one embodiment, the width of the camera lug 113 is smaller than the width of the limiting groove 1231. That is, there is a gap between the camera lug 113 and the groove wall support 12 of the limiting groove 1231. When the camera body 112 is calibrated, the camera lug 113 can move or rotate through these gaps. After the camera body 112 is calibrated, the gaps can be filled during welding with welding rods, ensuring a tight connection between the camera lug 113 and the groove wall of the limiting groove 1231.

[0056] Preferably, such as Figure 3 and Figure 6 As shown, in one embodiment, the elastic structural member 13 is a square elastic block disposed within the limiting groove 1231 to support the camera mount 113. With this configuration, when the camera body 112 is calibrated, the camera mount 113 rotates and compresses the elastic block. The elastic block deforms to fill the angle change between the bottom of the limiting groove 1231 and the camera mount 113. After the camera body 112 is calibrated, the camera mount 113 is fixedly connected to the limiting groove 1231, and the elastic block remains in its deformed state, fixed within the limiting groove 1231 to support the camera mount 113.

[0057] More preferably, such as Figure 4 As shown, in one embodiment, the camera mount 113 has a positioning hole 1131. The positioning hole 1131 is used to cooperate with a calibration tool to drive the camera mount 113 to rotate or move through the positioning hole 1131.

[0058] Further, please refer to Figure 2 , Figure 7 and Figure 8To calibrate the multi-view camera 10 as described above, the present invention provides a multi-view camera adjustment device 20, which includes a calibration plate 21, a support assembly 22, and an adjustment fixture 23. The calibration plate 21 has a calibration mark 211 corresponding to the mounting hole 121 of the bracket 12 of the multi-view camera 10; that is, the position of the calibration mark 211 is the calibration position of the multi-view camera 10. The calibration plate 21 is mounted on the support assembly 22, which supports the bracket 12 so that the bracket 12 is positioned above the calibration plate 21. The adjustment fixture 23 is disposed above the support assembly 22 and is used to grasp and rotate or move the camera 11 of the multi-view camera 10 so that the calibration cursor 111 of the camera 11 is aligned with the calibration mark 211. In other words, when assembling the multi-view camera 10, firstly, the bracket 12 is placed on the support component 22, so that the mounting hole 121 of the bracket 12 corresponds to the calibration mark 211; then, the camera 11 is inserted into the mounting hole 121 and powered on. After the camera 11 forms an image, the software calculates the imaging center of the camera 11 based on the pixel size and forms a calibration cursor 111 at the imaging center of the camera 11. At the same time, the camera 11 takes a picture of the calibration mark 211 on the calibration plate to compare the position difference with the calibration cursor 111; then, the camera 11 is gripped by the adjustment fixture 23, and the camera 11 is rotated or moved by the adjustment fixture 23 so that the calibration cursor 111 formed by the imaging center of the camera 11 coincides with the calibration mark 211 on the calibration plate 21; finally, the camera 11 is fixedly connected to the bracket 12. With this configuration, the assembly personnel can use the multi-camera adjustment device 20 to calibrate the multi-camera 10 during assembly. Since the mounting hole 121 corresponds to the calibration mark 211 in advance, only slight adjustments to the camera 11 are needed to make the positioning cursor coincide with the calibration mark 211, which simplifies the calibration steps of the multi-camera 10 and reduces the calibration difficulty of the multi-camera 10.

[0059] Optionally, such as Figure 3 and Figure 4As shown, in one embodiment, the adjustment fixture 23 includes a handle 231 and a limiting claw 232. The limiting claw 232 includes a connecting arm 2321 fixed to the handle 231 and a pair of positioning pins 2322 fixed to both ends of the connecting arm 2321. The positioning pins 2322 are used to insert into the positioning holes 1131 of the camera mount 113 of the camera 11. In other words, the handle 231 can be located in the middle of the connecting arm 2321, and the two positioning pins 2322 can be respectively located at both ends of the connecting arm 2321. The handle 231 and the positioning pins 2322 are respectively located on both sides of the connecting arm 2321. When the positioning pins 2322 are inserted into the positioning holes 1131 of the camera mount 113, the assembler can use the handle 231 to drive the camera mount 113 to rotate or move, which is simple and labor-saving. The limiting claw 232 can also be implemented as other structures capable of gripping the camera 11 to drive the camera 11 to rotate or move.

[0060] Preferably, such as Figure 4 and Figure 5 As shown, in one embodiment, the limiting claw 232 further includes a positioning block 2323 protruding from the outer surface of the positioning post 2322, the positioning block 2323 being used to abut against the camera mount 113. With this configuration, when the assembler rotates the camera mount 113 using the adjusting fixture 23, the positioning block 2323 can press against the camera mount 113, causing the elastic block to deform, thereby enhancing the limiting claw 232's gripping ability on the camera 11 and preventing the positioning post 2322 from dislodging from the positioning hole 1131.

[0061] In particular, such as Figure 2 As shown, in one embodiment, the support assembly 22 includes a pair of support arms 221, a support platform 222 fixed to the support arms 221, and a label platform 223 slidably connected to the support arms 221. The support platform 222 supports the bracket 12, and the label 21 is mounted on the label platform 223. With this configuration, the label platform 223 can slide along the support wall to move away from or towards the support platform 222, adapting to multi-view cameras 10 with various angles or shapes.

[0062] It is worth noting that, such as Figure 7 and Figure 8 As shown, in one embodiment, both the calibration mark 211 and the calibration cursor 111 are cross-shaped, so that the assembler can more accurately align the calibration cursor 111 with the calibration mark 211.

[0063] Further, please refer to Figure 9To more clearly demonstrate the advantages of the multi-view camera 10 of the present invention, the present invention provides a method for assembling a multi-view camera 10 as described above. The method for assembling a multi-view camera 10 includes the following steps:

[0064] S100. The elastic structure 13 is installed on the bracket 12 of the multi-view camera 10, and a pair of cameras 11 of the multi-view camera 10 are respectively inserted into a pair of mounting holes 121 of the bracket 12, so that the elastic structure 13 is located between the bracket 12 and the camera 11.

[0065] S200, Place the bracket 12 on the support component 22 of the multi-view camera adjustment device 20, and power on the camera 11 so that the camera 11 forms a calibration cursor 111;

[0066] S300, by adjusting the fixture 23, the camera 11 is grasped and rotated or moved so that the calibration cursor 111 is aligned with the calibration mark 211 on the calibration plate 21 of the carrier component 22; and

[0067] S400, fix the camera 11 to the bracket 12.

[0068] In this way, according to the assembly method of the multi-view camera 10, the assembler can quickly calibrate and assemble the multi-view camera 10, simplifying the calibration steps of the multi-view camera 10 and reducing the difficulty of subsequent calibration of the multi-view camera 10.

[0069] Optionally, such as Figure 10 As shown, in one embodiment, step S100, which involves mounting the elastic structure 13 onto the bracket 12 of the multi-view camera 10 and inserting a pair of cameras 11 of the multi-view camera 10 into a pair of mounting holes 121 of the bracket 12, so that the elastic structure 13 is located between the bracket 12 and the cameras 11, includes:

[0070] S110, Assemble the elastic structural member 13 within the limiting groove 1231 of the fixing block 123 of the bracket 12; and

[0071] S120. Insert the camera body 112 of the camera 11 into the mounting hole 121, and assemble the camera bracket 113 into the limiting groove 1231.

[0072] In this way, the elastic structural member 13 is set in the limiting groove 1231, which can provide support for the camera bracket 113 when adjusting the camera 11, so that the movement and rotation of the camera bracket 113 are more stable and the calibration difficulty of the multi-view camera 10 is reduced.

[0073] Optionally, such as Figure 11 As shown, in one embodiment, step S300, which involves adjusting the fixture 23 to grasp and rotate or move the camera 11 so that the calibration cursor 111 is aligned with the calibration mark 211 on the calibration plate 21 of the carrier component 22, includes:

[0074] S310, The camera bracket 113 is gripped by the limiting claw 232 of the adjusting fixture 23; and S320, The limiting claw 232 is rotated or moved by the handle 231 of the adjusting fixture 23, so that the camera body 112 rotates or moves.

[0075] Understandably, the assembly personnel can move or rotate the limiting claw 232 using the handle 231, thereby moving or rotating the camera mount 113, making the operation simple and convenient. Furthermore, when the assembly personnel need to grasp the camera mount 113, they only need to insert the positioning pin 2322 into the positioning hole 1131; when they need to release the camera mount 113, they only need to pull the positioning pin 2322 out of the positioning hole 1131.

[0076] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
