Embodiment Construction

[0027] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only It is a part of the embodiments of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0028] As described in the background art, if the irradiation angle of the laser lens of the laser device cannot be adjusted immediately and accurately, it is difficult to meet the requirements of the low-illuminance camera for the light source, resulting in unclear imaging.

[0029] To solve the above problems, see Figure 1 to Figure 5 As show...

Abstract

The invention discloses a camera lens adjusting device and a night vision system. The device comprises a mounting rack, a camera lens holder and a control portion. The camera lens holder is connectedwith the mounting rack, a camera lens mounting hole is formed in the camera lens holder, and a camera lens is rotationally mounted in the camera lens mounting hole. The control portion is arranged onthe mounting rack and comprises drive assemblies and adjusting worms. The drive assemblies and the adjusting worms are in drive connection. The adjusting worms and the camera lens holder are in driveconnection. The drive assemblies are used for driving the adjusting worms to rotate so as to adjust the angle of the camera lens holder. Spiral movement of the adjusting worms is adjusted to achieve fine adjustment and precise adjustment on the angle of the camera lens holder, and therefore the requirement of precise adjustment is met, the camera lens adjusting device is matched with the radiationcenter of a low-illumination camera and other equipment immediately and precisely, and the low-illumination camera and other equipment are assisted in obtaining distinct images.

Description

Technical field [0001] The present invention relates to the field of night vision technology, in particular to a lens adjustment device and a night vision system. Background technique [0002] Night vision technology refers to a photoelectric technology that realizes night observation by means of photoelectric imaging devices. Mainly divided into active infrared night vision technology and passive infrared night vision technology. Among them, active infrared refers to the processing of supplementing infrared light for the area to be observed, and imaging by infrared light reflected by the observed object. The passive infrared mainly refers to long-wave infrared imaging by sensing the infrared rays emitted by the observation object. Infrared night vision technology plays an important role in forest fire prevention, railway monitoring, and police evidence collection. [0003] However, in traditional laser night vision equipment, due to the distance between the two optical axes, it...
