Abstract

Because of the influence of atmosphere, the characteristics of the sensor and the image recording system, the quality of on-orbit obtained satellite images maybe get lower. The radiation distortion is caused by various factors, such as the blurring of the imaging system, non-linear amplitude response, vignetting and shadows, transmission noise, atmospheric interference, the changes of surface exposure and the radiance changes with the angle. According to the actual characteristics of high-resolution satellite images, we presented a radiation correction method which solved the image distortion problem. The radiation correction can provide a good basis for the image geometric correction, image fusion, etc. By the actual obtaining data of satellite on-orbit experiments, this program solves the problems of chrominance, mosaics, correction, drop-out lines, and noise existed in the images which are obtained by the raw data after decryption and decompression. The radiation correction can provide a good basis for the image mapping process, image fusion, etc.
