Description

Technical Field

[0001] This utility model belongs to the field of vision lens technology, specifically relating to a free-spinning adjustment device for a telecentric lens. Background Technology

[0002] A telecentric lens is used to correct parallax problems that may occur in traditional lenses during the imaging process. It can ensure that the magnification of the image does not change with the distance between the object and the lens within a certain object distance range. In other words, if the distance between a regular lens and the subject changes during shooting, problems such as distortion and blurred boundaries will occur.

[0003] Currently, the common method of using telecentric lenses is to first fix the telecentric lens and then connect the camera to the telecentric lens. However, when shooting various types of objects, especially objects with large variations in size and height, or when shooting multiple images in a stitched format, this method often requires repeated adjustments to the position and state of the entire shooting module. This can lead to repeated adjustments and disassemblies of the shooting module, resulting in inconvenience during shooting. Utility Model Content

[0004] The purpose of this invention is to provide a free-spinning adjustment device for telecentric lenses, in order to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A idling adjustment device for a telecentric lens includes a bracket for fixing the telecentric lens and a camera used in conjunction with it. The camera is mounted on the bracket and connected to the telecentric lens. The bracket is equipped with an adjustment mechanism.

[0007] A three-dimensional adjustment frame, which is a device in the adjustment mechanism used to support the bracket and adjust the position of the telecentric lens, is composed of a Z-axis frame, an X-axis frame and a Y-axis frame that are connected to each other and form a coordinate system structure. The bracket is connected to the X-axis frame.

[0008] The bracket is also equipped with a free-spinning structure that matches the camera, and the free-spinning structure is located on the bracket.

[0009] The Z-axis frame, X-axis frame, and Y-axis frame are all guide rails. Each guide rail includes a track and a slider. The slider is slidably mounted on the track. The slider of the Z-axis frame is connected to the Y-axis frame, the slider of the Y-axis frame is connected to the X-axis frame, and the slider of the X-axis frame is connected to the support.

[0010] The Z-axis frame has an L-shaped connecting block at the end of its track, with the right-angle opening of the L-shaped connecting block facing away from the Z-axis frame.

[0011] The idling structure includes an extension sleeve, a rotating plate, a motor, and a drive wheel. The bracket is C-shaped. The telecentric lens is located on the lower side of the opening of the bracket. The rotating plate is rotatably located on the upper side of the bracket. The extension sleeve is concentrically connected to the rotating plate and corresponds to the position of the camera lens. The extension sleeve is rotatably connected to the telecentric lens. The motor is located on the upper side of the bracket. The drive wheel is connected to the output shaft of the motor and engages with the side of the rotating plate.

[0012] This application has at least the following advantages compared to the prior art:

[0013] This application, through the setting of a three-dimensional adjustable skeleton, enables the targeted adjustment of the shooting position of the telecentric lens according to the actual shooting environment during the shooting process using a telecentric lens and camera.

[0018] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1-2 As shown, an idle adjustment device for a telecentric lens 1 includes a bracket 12 for fixing the telecentric lens 1 and a camera 11 for use in conjunction. The camera 11 is mounted on the bracket and connected to the telecentric lens 1. The bracket is equipped with an adjustment mechanism.

[0020] The three-dimensional adjustment frame is a device in the adjustment mechanism used to support the bracket and adjust the position of the telecentric lens 1. The three-dimensional adjustment frame consists of Z-axis frame 2, X-axis frame 3 and Y-axis frame 4 that are connected to each other and form a coordinate system structure. The bracket is connected to X-axis frame 3.

[0021] The bracket is also equipped with a free-spinning structure that matches the camera 11. The free-spinning structure is located on the bracket.

[0022] During filming, the position of the entire camera 11 and telecentric lens 1 can be adjusted using a three-dimensional adjustment frame based on the position of the subject. Specifically, the three-dimensional coordinate systems corresponding to the Z-axis frame 2, X-axis frame 3, and Y-axis frame 4 are adjusted according to the actual filming state, thereby changing the filming height and position of the telecentric lens 1. This allows for adjustment of the filming state based on the relationship between the telecentric lens 1 and the subject, thus improving the accuracy and clarity of the filming. Compared to conventional filming methods, this approach is more flexible and allows for adaptive adjustments to the filming state during post-production filming.

[0023] Z-axis frame 2, X-axis frame 3 and Y-axis frame 4 are all guide rails. The guide rails include a track 21 and a slider 22. The slider 22 is slidably mounted on the track 21. The slider 22 of Z-axis frame 2 is connected to Y-axis frame 4. The slider 22 of Y-axis frame 4 is connected to X-axis frame 3. The slider 22 of X-axis frame 3 is connected to the bracket.

[0024] In this application, the track 21 provides the sliding direction and connection support, while the slider 22 serves as a connection between adjacent shafts. The track 21 and slider 22 in this application can be electrically controlled, meaning the slider 22 has a built-in motor 62 connected to a roller. The movement of the slider 22 on the track 21 can be achieved by driving the roller with the motor 62. In some embodiments, the motor 62 can also be used in conjunction with a lead screw, where the lead screw is rotatably mounted on the track 21, and the slider 22 is threadedly connected to the lead screw and slides against the track 21. The movement of the slider 22 can be achieved by driving the lead screw with the motor 62. This application only points out one or more methods that can be implemented by those skilled in the art and does not limit the specific driving or guiding structure or device technology of this application. Therefore, no further technical details are provided here, but it is not limited to the technical methods referred to in this application by those skilled in the art.

[0025] The track 21 of the Z-axis frame 2 is provided with an L-shaped connecting block 5 at its end, and the right-angle opening of the L-shaped connecting block 5 faces away from the Z-axis frame 2.

[0026] The L-shaped connecting block 5 can be set by setting the Z-axis bracket 2 vertically to the ground or parallel to the ground to switch the shooting orientation of the camera 11 and the telecentric lens 1, so as to meet more different shooting angle or state requirements. The specific connection method of the L-shaped connecting block 5 can be bolt connection or other more convenient methods such as buckle. In some embodiments, the L-shaped connecting block 5 can also be set with a hinge, and the motor 62 drives the rotating shaft at the hinge to achieve more angles and more convenient shooting control effects.

[0027] The idling structure includes an extension sleeve 6, a rotating plate 61, a motor 62, and a drive wheel 63. The bracket is C-shaped. The telecentric lens 1 is located on the lower side of the opening of the bracket. The rotating plate 61 is rotatably located on the upper side of the bracket. The extension sleeve 6 is concentrically connected to the rotating plate 61 and corresponds to the position of the camera lens. The extension sleeve 6 is rotatably connected to the telecentric lens 1. The motor 62 is located on the upper side of the bracket. The drive wheel 63 is connected to the output shaft of the motor 62 and engages with the side of the rotating plate 61.

[0028] When further correction of the camera 11 and telecentric lens 1 and the focal plane of the subject is required, the rotating plate 61 can be driven by the drive wheel 63. At this time, the rotating plate 61 will simultaneously drive the extension sleeve 6 and the motor 62 to rotate. At this time, the angle between the motor 62 and the telecentric lens 1 will change, thereby correcting the accuracy of the camera sensor and further improving the clarity of the shot.

[0029] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
