Embodiment Construction

[0019] The invention relates to a TDICCD image movement detection and compensation method. The basic principle of the image movement speed calculation is to image the same ground object in a short time to obtain two area array images. According to the imaging time interval and the image movement distance, the image can be obtained. Therefore, the integral time of TDICCD can be calculated by formula (1), (2), and (3).

[0020] The specific implementation steps of the present invention are as follows image 3 As shown, the process is as follows:

[0021] figure 1 The satellite system shown is equipped with a TDICCD camera and a CMOS camera. Assuming that the operating altitude of the satellite is H and the focal length of the TDICCD camera is f 1 , The image speed is V 1 ; Focal length of CMOS camera f 2 , The image speed is V 2 . The running speed of the ground feature is V Ground , For two cameras installed on the same platform, the movement speed of the ground object is the same...

Abstract

The present invention relates to a TDICCD image motion detection and compensation method which is different from mechanical image motion compensation and laser ranging image motion compensation schemes, in load configuration of unknown elevation remote sensing detection, only a CMOS small camera and a proper amount of computing resources are added for real-time detection of image motion velocity of a ground object at an unknown elevation in a TDICCD focal plane, a given algorithm is used for real-time calculation of integral time Tint, image motion compensation is realized, and image quality degradation due to image motion can be improved to some extent. In deep space exploration missions, and because elevation information of a planet to be detected is unknown, a traditional calculation method is not feasible for integral time acquisition. The image motion compensation is realized by use of a CMOS + TDICCD dual camera model, the TDICCD image motion detection and compensation method is realizable on the planet, and original image quality can be effectively improved.

Description

Technical field [0001] The invention relates to a TDICCD image shift detection and compensation method, belonging to the technical field of aerospace remote sensing. Background technique [0002] The integration time of TDICCD must match the image movement speed on the focal plane. The mismatch between the two will produce image shift. The existence of image shift will cause image blur, grayscale distortion, contrast and resolution degradation, etc., which greatly affects the quality of the image, and makes the target difficult to identify or extract. It performs image motion compensation. [0003] There are many reasons for the image shift of the space optical TDICCD camera. At present, it is mainly aimed at the compensation of the forward image shift caused by the forward flight of the aircraft. At present, mechanical image motion compensation methods and optical image motion compensation methods are mostly used, which are relatively expensive. Summary of the invention [0004]...
