Description

Technical Field

[0001] The present disclosure relates to the technical field of automotive camera focusing, and particularly to a dual-focal-length camera calibration and focusing device and equipment. Background Art

[0002] With the wide use of new energy vehicles, cameras have also been widely applied to new energy vehicles. To ensure the accuracy of the factory focal length of the camera, people usually pre-focus the camera before leaving the factory. Some manufacturers have also made further adjustments to the pre-focusing process.

[0003] For example, Chinese Patent Document CN111239958A discloses an automatic camera focusing device, including a focusing mechanism. The focusing mechanism includes a lifting drive assembly, a bracket connected to the lifting drive assembly, and a rotating assembly and a clamping assembly mounted on the bracket; the rotating assembly includes a rotating drive, a driving wheel connected to the rotating drive, a driven wheel mounted on the bracket, and a transmission belt sleeved on the driving wheel and the driven wheel; the clamping assembly includes a clamping drive and two clamping members connected to the clamping drive, and the two clamping members are respectively arranged on opposite sides of the transmission belt, and the clamping members have clamping portions.

[0004] However, the design of the above automatic camera focusing device has the following problems:

[0005] Although the above automatic camera focusing device can drive the two side portions of the transmission belt to closely adhere to the circumferential side of the camera through the clamping portion for rotational focusing, due to the differences in the heights and calibration requirements of cameras with different focal lengths on the vehicle, when the above automatic camera focusing device adjusts cameras with different focal lengths, it is necessary to repeatedly adjust according to the calibration requirements. Especially when the focal length difference between the front and rear cameras is more than 150 mm, it will lead to an increase in the adjustment range and cause the operation process to be cumbersome. Summary of the Utility Model

[0006] The purpose of the present disclosure is to overcome the deficiencies in the prior art and provide a dual-focal-length camera calibration and focusing device and equipment that can perform targeted calibration and focusing on cameras with different focal lengths.

[0007] The purpose of the present disclosure is achieved through the following technical solutions:

[0009] The dual-focal-length camera calibration and focusing device further includes a high-focal-length focusing mechanism, a high-focal-length calibration mechanism, and a low-focal-length calibration and focusing mechanism;

[0010] The high focal length calibration mechanism is arranged above the high focal length conveying mechanism, and the high focal length calibration mechanism is used for calibrating the clarity of the high focal length camera; the high focal length focusing mechanism is arranged between the high focal length calibration mechanism and the high focal length conveying mechanism and is arranged opposite to the high focal length calibration mechanism; the low focal length calibration focusing mechanism includes a clamping focusing component and a low focal length calibration plate.

The rotating clamping frame is rotatably arranged in the rotating port. The teleconverter lens covers above the rotating port. The rotating clamping frame is arranged opposite to the high focal length calibration mechanism through the teleconverter lens.

[0014] In one embodiment, the high focal length calibration mechanism includes a setting frame and a high focal length calibration plate; the setting frame is arranged above the mounting frame; the high focal length calibration plate is mounted on the setting frame and is arranged opposite to the teleconverter lens.

[0015] In one embodiment, the low focal length calibration plate or the high focal length calibration plate is a film calibration plate.

[0016] In one embodiment, the dual focal length camera calibration focusing device further includes an appearance detection mechanism. The appearance detection mechanism straddles above the high focal length conveying mechanism and the low focal length conveying mechanism.

[0017] In one embodiment, the appearance detection mechanism includes a horizontal frame and two shooting cameras. The horizontal frame spans above the high focal length conveying mechanism and the low focal length conveying mechanism. The two shooting cameras are respectively arranged on the horizontal frame. One shooting camera is arranged opposite to the high focal length conveying mechanism, and the other shooting camera is arranged opposite to the low focal length conveying mechanism.

[0018] A dual-focal length camera calibration and focusing device includes the dual-focal length camera calibration and focusing device of any of the above embodiments.

[0020] Compared with the prior art, the present disclosure has at least the following advantages:

[0021] 1) By arranging the high focal length calibration mechanism above the high focal length conveying mechanism, since the high focal length focusing mechanism is arranged between the high focal length calibration mechanism and the high focal length conveying mechanism, when the high focal length conveying mechanism conveys the high focal length camera below the high focal length focusing mechanism, the high focal length focusing mechanism can focus on the high focal length camera.

[0023] 3) Compared with the existing camera autofocus devices, the above-mentioned dual-focal-length camera calibration and focusing device can place the high-focal-length camera on the high-focal-length transfer mechanism so that the high-focal-length focusing mechanism and the high-focal-length calibration mechanism can perform targeted focusing and calibration on the high-focal-length camera. At the same time, it can place the low-focal-length camera on the low-focal-length transfer mechanism so that the low-focal-length calibration and focusing mechanism can perform targeted focusing and calibration on the low-focal-length camera. As a result, the above-mentioned dual-focal-length camera calibration and focusing device can simultaneously perform targeted focusing and calibration on cameras of two focal lengths. Especially when the difference in the focal lengths of the cameras is more than 150 mm, it can place the camera with a lower focal length on the low-focal-length transfer mechanism and place the camera with a higher focal length on the high-focal-length transfer mechanism for separate processing, avoiding the operation process of large adjustments and being more convenient to use.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0034] To better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below with specific embodiments:

[0035] Such as Figure 1 And Figure 2As shown, the dual-focus camera calibration and focusing device 100 of an embodiment includes a high-focus focusing mechanism 130, a high-focus calibration mechanism 140, a low-focus calibration and focusing mechanism 150, a high-focus transmission mechanism 110 and a low-focus transmission mechanism 120 arranged side by side; the high-focus transmission mechanism 110 is used to transmit a high-focus camera; the low-focus transmission mechanism 120 is used to transmit a low-focus camera; the high-focus calibration mechanism 140 is arranged above the high-focus transmission mechanism 110, and the high-focus calibration mechanism 140 is used for calibrating the clarity of the high-focus camera; the high-focus focusing mechanism 130 is arranged between the high-focus calibration mechanism 140 and the high-focus transmission mechanism 110 and is arranged opposite to the high-focus calibration mechanism 140; the low-focus calibration and focusing mechanism 150 includes a clamping and focusing component 1510 and a low-focus calibration plate 1520, the clamping and focusing component 1510 is arranged above the low-focus transmission mechanism 120 and is provided with a rotating bayonet 151a arranged opposite to the low-focus transmission mechanism 120; the low-focus calibration plate 1520 is arranged on the low-focus transmission mechanism 120 and is arranged opposite to the rotating bayonet 151a, and the low-focus calibration plate 1520 is used for calibrating the clarity of the low-focus camera.

[0036] It can be understood that by arranging the high-focus calibration mechanism 140 above the high-focus transmission mechanism 110, since the high-focus focusing mechanism 130 is arranged between the high-focus calibration mechanism 140 and the high-focus transmission mechanism 110, when the high-focus transmission mechanism 110 conveys the high-focus camera below the high-focus focusing mechanism 130, the high-focus focusing mechanism 130 can focus on the high-focus camera, and because the high-focus focusing mechanism 130 is arranged opposite to the high-focus calibration mechanism 140, the high-focus camera can calibrate the clarity through the high-focus calibration mechanism 140 during focusing.

[0037] It can be understood that by arranging the clamping and focusing component 1510 above the low-focus transmission mechanism 120, since the clamping and focusing component 1510 is provided with a rotating bayonet 151a arranged opposite to the low-focus transmission mechanism 120, when the low-focus transmission mechanism 120 conveys the low-focus camera below the clamping and focusing component 1510, the rotating bayonet 151a of the clamping and focusing component 1510 can clamp the low-focus camera for focusing, and because the low-focus calibration plate 1520 is arranged opposite to the rotating bayonet 151a, the low-focus camera can calibrate the clarity through the low-focus calibration plate 1520 during focusing.

[0038] It can be understood that, compared with the camera autofocus device in the prior art, the above-mentioned dual-focal-length camera calibration and focusing device 100 can place the high-focal-length camera on the high-focal-length conveying mechanism 110 and perform targeted focusing and calibration on the high-focal-length camera through the high-focal-length focusing mechanism 130 and the high-focal-length calibration mechanism 140. At the same time, it can place the low-focal-length camera on the low-focal-length conveying mechanism 120 and perform targeted focusing and calibration on the low-focal-length camera through the low-focal-length calibration and focusing mechanism 150, so that the above-mentioned dual-focal-length camera calibration and focusing device 100 can simultaneously perform targeted focusing and calibration on the cameras of two focal lengths. Especially when the difference in the focal lengths of the cameras is more than 150 mm, it is possible to place the camera with a lower focal length on the low-focal-length conveying mechanism 120 and place the camera with a higher focal length on the high-focal-length conveying mechanism 110 for separate processing, avoiding the operation process of large adjustments and making it more convenient to use.

[0039] It should be particularly noted that the focal length of the high-focal-length camera is greater than that of the low-focal-length camera. For example, the focal length of the high-focal-length camera can be 200 mm or more, and the focal length of the low-focal-length camera can be 50 mm or less. Of course, it is not limited specifically here, and those skilled in the art can choose according to needs.

[0040] Combined with Figure 2 As shown in the figure, in one embodiment, the clamping and focusing assembly 1510 includes a mounting bracket 1511 and a clamping rotating disk 1512. The mounting bracket 1511 is disposed above the low-focal-length conveying mechanism 120. The clamping rotating disk 1512 is rotatably disposed on the mounting bracket 1511. The rotating bayonet 151a is opened at the central position of the clamping rotating disk 1512. The low-focal-length calibration plate 1520 is mounted on the mounting bracket 1511. It can be understood that since the mounting bracket 1511 is disposed above the low-focal-length conveying mechanism 120, when the low-focal-length camera is transferred to the lower part of the mounting bracket 1511 through the low-focal-length conveying mechanism 120, by rotatably disposing the clamping rotating disk 1512 on the mounting bracket 1511, since the rotating bayonet 151a is opened at the central position of the clamping rotating disk 1512, the rotating bayonet 151a can clamp the low-focal-length camera and achieve focusing as the clamping rotating disk 1512 rotates.

[0041] Combined with Figure 2As shown, in one embodiment, an embedding opening 151b is formed in the mounting bracket 1511, and the clamping rotating disc 1512 is rotatably arranged in the embedding opening 151b; the low focal length calibration plate 1520 covers the embedding opening 151b. It can be understood that by rotatably arranging the clamping rotating disc 1512 in the embedding opening 151b, the clamping rotating disc 1512 can clamp the low focal length camera to rotate and focus more stably. At the same time, since the low focal length calibration plate 1520 covers the embedding opening 151b, the lens of the low focal length camera can be aligned with the low focal length calibration plate 1520, so that the low focal length camera can calibrate the clarity through the low focal length calibration plate 1520 during focusing.

[0042] Combined with Figure 1 and Figure 3 As shown, in one embodiment, the high focal length focusing mechanism 130 includes a mounting frame 1310, a rotating clamping frame 1320 and a teleconverter 1330; the mounting frame 1310 is arranged above the high focal length transmission mechanism 110; a rotating opening 1311 is formed in the mounting frame 1310, the rotating clamping frame 1320 is rotatably arranged in the rotating opening 1311, the teleconverter 1330 covers above the rotating opening 1311, and the rotating clamping frame 1320 is oppositely arranged with the high focal length calibration mechanism 140 through the teleconverter 1330. It can be understood that since the mounting frame 1310 is arranged above the high focal length transmission mechanism 110, when the high focal length camera is transferred to the lower part of the mounting frame 1310 through the high focal length transmission mechanism 110, by rotatably arranging the rotating clamping frame 1320 in the rotating opening 1311, the rotating clamping frame 1320 can clamp the high focal length camera to rotate for focusing. Also, because the teleconverter 1330 covers above the rotating opening 1311, the lens of the high focal length camera can be aligned with the high focal length calibration mechanism 140 through the teleconverter 1330, and the teleconverter 1330 can lengthen the field of view of the high focal length camera, so that the high focal length camera can simulate the situation of calibrating the high focal length calibration plate 1420 at a long distance, making the focusing of the high focal length camera more accurate.

[0043] Combined with Figure 1 and Figure 3As shown, in one embodiment, the high focal length calibration mechanism 140 includes a setting frame 1410 and a high focal length calibration plate 1420; the setting frame 1410 is disposed above the installation frame 1310; the high focal length calibration plate 1420 is installed on the setting frame 1410 and is disposed opposite to the teleconverter lens 1330. It can be understood that since the setting frame 1410 is disposed above the installation frame 1310, when the high focal length camera is transferred to the lower part of the installation frame 1310 through the high focal length transfer mechanism 110, the rotary clamping frame 1320 can clamp the high focal length camera. Also, because the high focal length calibration plate 1420 is installed on the setting frame 1410, by disposing the high focal length calibration plate 1420 opposite to the teleconverter lens 1330, the high focal length camera can be aligned with the high focal length calibration plate 1420 through the teleconverter lens 1330, thereby making the focusing of the high focal length camera more accurate.

[0044] In one embodiment, the low focal length calibration plate 1520 is a film icon calibration plate. It can be understood that the low focal length calibration plate 1520 being a film icon calibration plate enables the low focal length camera to determine the clarity of the marked points on the received film icon calibration plate and accurately focus the low focal length camera in real time through the low focal length calibration and focusing mechanism 150.

[0045] In one embodiment, the high focal length calibration plate 1420 is a film icon calibration plate. It can be understood that the high focal length calibration plate 1420 being a film icon calibration plate enables the high focal length camera to determine the clarity of the marked points on the received film icon calibration plate and accurately focus the high focal length camera in real time through the high focal length focusing mechanism 130.

[0046] Combined with Figure 4 As shown, in one embodiment, the dual focal length camera calibration and focusing device 100 further includes an appearance detection mechanism 160. The appearance detection mechanism 160 spans above the high focal length transfer mechanism 110 and the low focal length transfer mechanism 120. The appearance detection mechanism 160 is used to acquire and detect images of the camera. It can be understood that by making the appearance detection mechanism 160 span above the high focal length transfer mechanism 110 and the low focal length transfer mechanism 120, the appearance of the high focal length camera on the high focal length transfer mechanism 110 can be detected by the appearance detection mechanism 160, and at the same time, the appearance of the low focal length camera on the low focal length transfer mechanism 120 can be detected, so as to detect whether there is dirt or defects on the appearance of the high focal length camera or the low focal length camera.

[0047] Combined with Figure 4As shown, in one of the embodiments, the appearance detection mechanism 160 includes a horizontal frame 1610 and two shooting cameras 1620. The horizontal frame 1610 spans above the high focal length transmission mechanism 110 and the low focal length transmission mechanism 120. The two shooting cameras 1620 are respectively arranged on the horizontal frame 1610. One of the shooting cameras 1620 is arranged opposite to the high focal length transmission mechanism 110, and the other shooting camera 1620 is arranged opposite to the low focal length transmission mechanism 120. It can be understood that by arranging one of the shooting cameras 1620 opposite to the high focal length transmission mechanism 110, the image of the high focal length camera on the high focal length transmission mechanism 110 can be captured and analyzed by the corresponding shooting camera 1620. At the same time, by arranging one of the shooting cameras 1620 opposite to the low focal length transmission mechanism 120, the image of the low focal length camera on the low focal length transmission mechanism 120 can be captured and analyzed by the corresponding shooting camera 1620.

[0048] Combined with Figure 5 As shown, the present disclosure also provides a dual focal length camera calibration and focusing device 10, which includes the dual focal length camera calibration and focusing device 100 of any of the above embodiments. It can be understood that by applying the dual focal length camera calibration and focusing device 100 of the present disclosure in the dual focal length camera calibration and focusing device 10, the high focal length camera can be placed on the high focal length transmission mechanism 110, and the high focal length camera can be specifically focused and calibrated through the high focal length focusing mechanism 130 and the high focal length calibration mechanism 140. At the same time, the low focal length camera can be placed on the low focal length transmission mechanism 120, and the low focal length camera can be specifically focused and calibrated through the low focal length calibration and focusing mechanism 150, so that the above dual focal length camera calibration and focusing device 100 can specifically focus and calibrate the cameras of the two focal lengths at the same time. Especially when the difference between the focal lengths of the cameras is more than 150 mm, the camera with a lower focal length can be placed on the low focal length transmission mechanism 120, and the camera with a higher focal length can be placed on the high focal length transmission mechanism 110 for separate processing, avoiding the operation process of large adjustments and being more convenient to use.

[0049] Combined with Figure 1 And Figure 5As shown, in one of the embodiments, a light supplement board 200 is further provided above the dual-focus camera calibration and focusing device 100. It can be understood that by arranging the light supplement board 200 above the dual-focus camera calibration and focusing device 100, the dual-focus camera calibration and focusing device 100 can be supplemented with light through the light supplement board 200, so that the dual-focus camera calibration and focusing device 100 can be calibrated in a bright environment, further improving the calibration accuracy. Specifically, the light supplement board 200 is installed on a shelf so as to be suspended above the low-focus calibration board 1520 and the high-focus calibration board 1420.

[0050] Compared with the prior art, the present disclosure has at least the following advantages:

[0051] 1) By arranging the high-focus calibration mechanism 140 above the high-focus transfer mechanism 110, since the high-focus focusing mechanism 130 is arranged between the high-focus calibration mechanism 140 and the high-focus transfer mechanism 110, when the high-focus transfer mechanism 110 conveys the high-focus camera to the lower part of the high-focus focusing mechanism 130, the high-focus focusing mechanism 130 can focus on the high-focus camera. Also, because the high-focus focusing mechanism 130 and the high-focus calibration mechanism 140 are oppositely arranged, the high-focus camera can calibrate the clarity through the high-focus calibration mechanism 140 during focusing.

[0052] 2) By arranging the clamping and focusing assembly 1510 above the low-focus transfer mechanism 120, since the clamping and focusing assembly 1510 is provided with a rotating bayonet 151a oppositely arranged to the low-focus transfer mechanism 120, when the low-focus transfer mechanism 120 conveys the low-focus camera to the lower part of the clamping and focusing assembly 1510, the rotating bayonet 151a of the clamping and focusing assembly 1510 can clamp the low-focus camera for focusing. Also, because the low-focus calibration board 1520 and the rotating bayonet 151a are oppositely arranged, the low-focus camera can calibrate the clarity through the low-focus calibration board 1520 during focusing.

[0053] 3) Compared with the existing camera autofocus devices, the above-mentioned dual-focal-length camera calibration and focusing device 100 can place the high-focal-length camera on the high-focal-length conveying mechanism 110 so that the high-focal-length focusing mechanism 130 and the high-focal-length calibration mechanism 140 can perform targeted focusing and calibration on the high-focal-length camera. At the same time, it can place the low-focal-length camera on the low-focal-length conveying mechanism 120 so that the low-focal-length calibration and focusing mechanism 150 can perform targeted focusing and calibration on the low-focal-length camera. As a result, the above-mentioned dual-focal-length camera calibration and focusing device 100 can simultaneously perform targeted focusing and calibration on the cameras of two focal lengths. Especially when the difference in the focal lengths of the cameras is more than 150 mm, it can place the camera with a lower focal length on the low-focal-length conveying mechanism 120 and place the camera with a higher focal length on the high-focal-length conveying mechanism 110 for separate processing, avoiding the operation process of large adjustments and being more convenient to use.

[0054] The above embodiments only represent several implementation manners of the present disclosure. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several deformations and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
