Multispectral camera and unmanned aerial vehicle

Abstract

The invention discloses a multispectral camera and an unmanned aerial vehicle. The multispectral camera comprises an annular middle housing, an upper housing and a lower housing, wherein the upper housing and the lower housing cover openings in the two ends of the middle housing respectively; an upper housing circuit board is fixed in the upper housing; a middle housing circuit board and a lens module electrically connected with the middle housing circuit board are fixed in the middle housing, and the middle housing circuit board is electrically connected with the upper housing circuit board;and lens glass is fixed to the outer side of a lens through hole of the lower housing. The whole system structure in the camera is split into three relatively independent modules, so that the difficulty of whole assembly and adjustment is reduced; the lens module is assembled in a modular manner, so that the influence of installation and adjustment errors can be reduced, and errors of optical parameter indexes of the lens module caused by installation, debugging, maintenance and the like of other parts can be avoided; other module assemblies are not influenced when debugging, maintenance and the like are carried out on the upper housing circuit board and on-board components, so that the frequency of parameter debugging and calibration is reduced, and the assembly production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of spectral imaging, in particular to a multispectral camera and an unmanned aerial vehicle. Background technique [0002] With the development of spectral imaging technology, multispectral cameras have been widely used in UAV remote sensing fields such as agriculture, forestry, rivers, ecology, oceans, and emergency response. [0003] In an existing multispectral camera, it includes a cavity-type lower case and a cover-type upper case. The lens module, circuit board and other components are fixedly connected and placed inside the lower case as a whole, and then the upper case fits and covers the lower case opening to complete the machine assembly. In the subsequent use, when debugging and maintaining or customizing and replacing lens modules of other bands, the whole machine needs to be disassembled and adjusted, and the production process is cumbersome. [0004] Therefore, how to provide a multispectral ...
