Abstract

The invention relates to an aerial CCD imaging system, comprising a CCD sensor, a pre-amplification circuit, an A / D conversion circuit connected to the pre-amplification circuit; an FPGA circuit connected to the A / D conversion circuit, and used to convert digital signals After uniformity correction processing, output image signal through the image output interface provided on it; RS422 communication interface circuit; also includes power supply circuit; described CCD sensor and pre-amplification circuit are arranged on the first circuit board, and described power supply circuit is arranged on the second On the second circuit board, the FPGA circuit, the A / D conversion circuit and the RS422 communication interface circuit are arranged on the third circuit board, and the first circuit board, the second circuit board and the third circuit board are mutually orthogonally arranged. The first circuit board, the second circuit board and the third circuit board are respectively connected by rigid-flex boards. The invention effectively reduces the volume of the system, reduces the weight of the system, and at the same time effectively corrects the non-uniformity of the image.

Description

technical field [0001] The invention relates to the technical field of airborne photoelectric imaging, in particular to an aviation CCD imaging system and an aircraft. Background technique [0002] Aerial cameras include aerial reconnaissance cameras, aerial surveying and mapping cameras, aerial multispectral cameras and imaging spectrometers, which can be used in military intelligence search, national defense monitoring, change detection, precise mapping and target guidance, etc. Construction of targets such as silos, weapons testing grounds, and defense facilities, and preparations for military activities such as troop build-up and weapon deployment. Therefore, many countries in the world are actively developing aerial cameras for aerial remote sensing. As a branch of aerial cameras, high-resolution aerial CCD (charge coupled device) imaging reconnaissance cameras are more and more widely used in military affairs, especially in the detailed detection tasks of key areas, a...
