Embodiment

[0040] Such as figure 1 As shown, the embodiment of the present application provides a lens focusing device 100 . The lens focusing device 100 includes a base 10 , a laser triangulation stereo sensor body 20 and a focusing auxiliary mechanism 30 . Wherein, the laser triangular stereo sensor main body 20 comprises a mounting frame 21, a line laser 22, an image sensor 23 and a lens 24, and the line laser 22, the image sensor 23 and the lens 24 are all installed on the mounting frame 21, and the mounting frame 21 is movably installed on Base10. The focus auxiliary mechanism 30 is arranged on the base 10, and the movement of the laser triangular stereo sensor main body 20 relative to the base 10 can make the plane where the surface laser 221 emitted by the line laser 22 coincide with the reference surface 311 on the focus auxiliary mechanism 30, so that the reference surface 311 is aligned with the lens. The focal planes of 24 coincide. By moving the laser triangular stereo sens...

Abstract

The application provides a lens focusing device, which relates to the technical field of monitoring. The lens focusing device includes a base, a laser triangular stereo sensor body and a focusing auxiliary mechanism. The main body of the laser triangular stereo sensor includes a mounting frame, a line laser, an image sensor and a lens. The line laser, the image sensor and the lens are all mounted on the mounting frame, and the mounting frame is movably mounted on the base. The focusing auxiliary mechanism is arranged on the base, and the movement of the main body of the laser triangular stereo sensor relative to the base can make the plane where the surface laser emitted by the line laser coincide with the reference plane, so that the reference plane coincides with the focal plane of the lens. By moving the main body of the laser triangular stereo sensor so that the focal plane of the lens on the main body of the laser triangular stereo sensor coincides with the reference plane, the focus of the lens is realized and the range of focusing of the lens itself is reduced. By setting the difference between the main body of the laser triangular stereo sensor on the base The amount of movement enables the lens focusing device to adapt to different test distances.

Description

technical field [0001] The present application relates to the technical field of monitoring, and in particular, to a lens focusing device. Background technique [0002] At present, the focusing process of the laser triangle stereo sensor lens is complicated and takes a long time to focus, which brings great difficulties to the focusing of the imaging system. Contents of the invention [0003] An embodiment of the present application provides a lens focusing device to improve the problem of difficulty in focusing measurement by existing triangular stereo sensors. [0004] An embodiment of the present application provides a lens focusing device, including a base, a laser triangular stereo sensor body, and a focusing auxiliary mechanism. The main body of the laser triangular stereo sensor includes a mounting frame, a line laser, an image sensor and a lens. The line laser, the image sensor and the lens are all mounted on the mounting frame, and the mounting frame is movably m...
