Abstract
Description
Technical Field
[0001] This utility model relates to the field of image detection technology, and in particular to an image detection device. Background Technology
[0002] During automatic coupling, abnormal lens placement often prevents the coupling of single, double, or even multiple lenses. Typically, an image detection device is used to detect the lens's contour state. The lens's position and orientation are then corrected based on the detected contour state until the lens is in the correct position and orientation required for light propagation. This image detection device usually has a down-facing camera and a side camera, used to capture images of the lens's bottom and side, respectively, and the lens's position and orientation are adjusted based on the image information from these images. (Reference) Figure 1 and Figure 2 , Figure 1 This is a front view of an image detection device in the prior art. Figure 2 This is a top view of a prior art image detection device, which includes a down-facing camera 510, a side camera 520, a suction nozzle 530, and a lens 540. The suction nozzle 530 is used to hold the lens 540. The down-facing camera 510 captures an image of the bottom of the lens 540, and the side camera 520 captures an image of the side of the lens 540. However, using two cameras (a down-facing camera and a side camera) in the image detection device is too costly. Furthermore, the speed at which the computer detects and identifies the images captured by the two cameras separately using algorithms is relatively slow. Additionally, the time required to simultaneously capture key characteristic parts of the lens using imaging fitting algorithms is significant, severely increasing the working time of the image detection device and reducing its efficiency. Therefore, there is a need to propose an image detection device that uses the same camera to acquire image information of the lens at both detection ends and processes the acquired image information to reduce the cost and improve the efficiency of the image detection device. Utility Model Content
[0003] The purpose of this invention is to provide an image detection device to solve the problems of high cost and low efficiency of existing image detection devices.
[0004] To solve the above-mentioned technical problems, this utility model provides an image detection device, including an image acquisition component and an optical path assembly. The image acquisition component or the optical path assembly is movable, such that the first detection end of the object to be detected is located on the incident optical path of the image acquisition component, or the second detection end of the object to be detected is located on the incident optical path of the optical path assembly and the image acquisition component is located on the outgoing optical path of the optical path assembly.
[0005] Optionally, it may also include a first driving component, which drives the image acquisition component or the optical path component to move.
[0006] Optionally, the first driving component drives the optical path component to move.
[0007] Optionally, the first driving component includes a driver and a clamp, the clamp being disposed on the output end of the driver and used to hold the optical path component.
[0008] Optionally, the driver is an air pump.
[0009] Optionally, a second drive component may also be included to drive the movement of the object to be detected.
[0010] Optionally, the movement trajectories of the device under test and the optical path assembly are perpendicular to the incident optical path of the image acquisition device.
[0011] Optionally, the second driving component is a suction nozzle.
[0012] Optionally, the first driving component drives the image acquisition device to move.
[0013] Optionally, the incident light path of the optical path assembly is perpendicular to the outgoing light path of the optical path assembly, and the moving trajectory of the image acquisition device is parallel to the incident light path of the optical path assembly.
[0014] The image detection device provided by this utility model has the following beneficial effects:
[0015] Since the image detection device includes only one image acquisition unit, the first detection end of the object to be detected is located on the incident light path of the image acquisition unit, or the second detection end of the object to be detected is located on the incident light path of the optical path assembly and the image acquisition unit is located on the outgoing light path of the optical path assembly. Therefore, the image detection device can directly acquire the image information of the first detection end of the object to be detected, or it can acquire the image information of the second detection end of the object to be detected through the optical path assembly. The first and second detection ends are two different end faces of the object to be detected. Thus, the same image acquisition unit can acquire the image information of the two different end faces of the object to be detected, thereby enabling the image detection device to detect the contour state of the object to be detected and correct the position and orientation of the object to be detected by the contour state of the lens detected by the image detection device until the object to be detected is in the normal position and orientation required for light propagation. Because only one image acquisition unit is used, costs are saved. Furthermore, the speed of computer detection and recognition of images acquired by the image acquisition unit through algorithms is improved, and the time required to capture key characterization parts of the object to be detected using imaging fitting algorithms is saved, thus improving work efficiency. Furthermore, since the image acquisition device or the optical path assembly is movable, the position of the image acquisition device or the position of the optical path assembly can be adjusted to enable the image acquisition device to acquire image information from both end faces of the object to be detected. Compared with an image detection device in which the image acquisition device is stationary relative to the optical path assembly, the structure of the optical path assembly can be simplified, and the requirements for the breadth of the image acquisition range of the image acquisition device can be reduced, further reducing costs.

[0037] Example 1
[0038] refer to Figure 3 , Figure 4 and Figure 5 , Figure 3 This is a front view of the image detection device in Embodiment 1 of this utility model. Figure 4 This is a side view of the image detection device in Embodiment 1 of this utility model. Figure 5 This is an isometric view of the image detection device in Embodiment 1 of this utility model. This embodiment provides an image detection device, including an image acquisition component 100 and an optical path assembly 200. The image acquisition component 100 or the optical path assembly 200 is movable such that the first detection end of the object to be detected 600 is located on the incident light path of the image acquisition component 100, or the second detection end of the object to be detected 600 is located on the incident light path of the optical path assembly 200 and the image acquisition component 100 is located on the outgoing light path of the optical path assembly 200.
[0039] Since the image detection device includes only one image acquisition element 100, the first detection end of the device to be detected 600 is located on the incident light path of the image acquisition element 100, or the second detection end of the device to be detected 600 is located on the incident light path of the optical path assembly 200 and the image acquisition element 100 is located on the outgoing light path of the optical path assembly 200. Therefore, the image detection device can directly acquire the image information of the first detection end of the device to be detected 600, or it can acquire the image information of the second detection end of the device to be detected 600 through the optical path assembly 200. The first detection end and the second detection end are two different end faces of the device to be detected 600. In this way, the image information of the two different end faces of the device to be detected 600 can be acquired by the same image acquisition element 100, thereby enabling the image detection device to detect the contour state of the device to be detected 600, and to correct the position and orientation of the device to be detected 600 by the contour state of the lens detected by the image detection device, until the device to be detected 600 is in the normal position and orientation required for light propagation. Since only one image acquisition unit 100 is used, costs can be saved. Furthermore, the speed at which the computer detects and recognizes the images acquired by the image acquisition unit 100 using algorithms can be improved, and the time required to capture key characterization areas of the object under test 600 using imaging fitting algorithms can be saved, thus improving work efficiency. In addition, since the image acquisition unit 100 or the optical path assembly 200 is movable, the position of the image acquisition unit 100 or the optical path assembly 200 can be adjusted to acquire image information from both end faces of the object under test 600. Compared to an image detection device where the image acquisition unit 100 is stationary relative to the optical path assembly 200, the structure of the optical path assembly 200 can be simplified, and the requirement for the breadth of the image acquisition range of the image acquisition unit 100 can be reduced, further lowering costs.
[0040] In this embodiment, the image detection device further includes a first driving component 300, which drives the image acquisition component 100 or the optical path component 200 to move.
[0041] Specifically, in this embodiment, the first driving component 300 drives the optical path component 200 to move. Thus, the movement of the optical path component 200 enables the image acquisition component 100 to acquire image information from the second detection end of the device to be detected 600.
[0042] The first driving component 300 includes a driver and a clamp, the clamp being disposed on the output end of the driver and used to hold the optical path component 200.
[0043] Preferably, the driver is an air pump. In other embodiments, the driver may also be other linear drivers, such as a combination of a motor and a linear guide.
[0044] Preferably, the image detection device further includes a second driving component 400 for driving the movement of the object to be detected 600. This allows both the object to be detected 600 and the optical path component 200 to move relative to the image acquisition component 100, thereby facilitating the image acquisition component 100 to acquire image information from the first detection end and the second detection end of the object to be detected 600.
[0045] Furthermore, the movement trajectories of the device under test 600 and the optical path assembly 200 are perpendicular to the incident light path of the image acquisition device 100. This simplifies the movement of the device under test 600 and the optical path assembly 200, improving the detection efficiency of the image detection device.
[0046] The second drive component 400 includes a suction nozzle.
[0047] The optical path component 200 is a reflector. For example, it can be a prism or a plane mirror.
[0048] The image acquisition device 100 is a camera. For example, it can also be a video camera.
[0049] In this embodiment, the device to be tested 600 is a lens, the first detection end is the end face of the lens perpendicular to the optical axis of the lens, and the second detection end is the end face of the lens parallel to the optical axis of the lens.
[0050] Example 2
[0051] This embodiment provides an image detection device. The difference from Embodiment 1 is that the first driving component in the image detection device of this embodiment only drives the image acquisition component 100 to move.
[0052] Furthermore, the incident light path of the optical path assembly 200 is perpendicular to the outgoing light path of the optical path assembly 200, and the moving trajectory of the image acquisition unit 100 is parallel to the incident light path of the optical path assembly 200. Thus, image information from two mutually perpendicular end faces of the device under test 600 can be acquired by the image acquisition unit 100. For example, when the device under test 600 is a lens, image information from the end face perpendicular to the lens optical axis and image information from the end face parallel to the lens optical axis can be acquired.
[0053] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
