Problems solved by technology
In the previous airborne stabilized aiming turrets, the large and small field of view switching camera devices were mostly used, and the optics mostly used the fold-back optical path. Multiple independent dual-field cameras simultaneously acquired multiple spectral videos, which was difficult to meet the requirements of miniaturization and light weight. need

Description
technical field [0001] The invention belongs to the technical field of image acquisition, and relates to a multi-channel continuous zoom camera device suitable for airborne multi-spectral reconnaissance equipment. Background technique [0002] Airborne multispectral reconnaissance equipment is a new type of unmanned aerial vehicle mission equipment that uses multispectral technology to carry out reconnaissance. It consists of multispectral cameras, laser light detectors, and stable turrets. Among them, the multispectral camera obtains the spectral image of the target, and distinguishes the detection imaging object according to the spectral characteristics difference between the target and the background. By configuring the sensitive wavelength, the detection object of a specific type can stand out from the background, and the camouflage can be camouflaged within the working distance. Objects are distinguished from their adaptive context. Improves reconnaissance of battlefie...
