Design of Multi-Spectral Large Format Chromatic CCD Digital Aerial Photogrammetric Camera
多光谱大面阵彩色CCD数字航测相机设计

Based on the characteristic of large scale digital aerial photogrammetric system,a set of multi-spectral,high resolution digital camera system was developed by high integration of optical,mechanical and electrical hardware.The system are chiefly composed of four CCD cameras,one of which can obtain panchromatic image with a 9 k×9 k CCD.The other three cameras respectively gain R,G and B image.The chromatic image is acquired by the synthesis of R,G and B image.The key technology and methods of camera system are represented in detail.The system was tested in Y-5 remote-sensing airplane,after disposing and analyzing the acquired image,the system can meet the demand of large scaled digital aerial photogrammetry.
