Line CCD Satellite remote sensing images imaging model and algorithm

With the rapid development of remote sensing technology , the high-resolution linear array CCD remote sensing satellite images have been widely used . Effective use of remote sensing satellite image sensor imaging model must first solve the problem . The use of high-precision satellite remote sensing data such as SPOT5 satellite data , the lack of control point or no target ground position of the control point area , has a very important significance . Firstly, start from the principle of the spatial orientation of the linear array CCD remote sensing satellite images to study the linear array CCD sensor and then start from the most common of several generic sensor model based on the the collinear equation of physical sensor model , affine transformation model , rational function the model geometric model , summarized , compared and analyzed . Second , for the single-wire the pushbroom sensor 's imaging geometry , six satellite orbits Kepler parameters and three sensor attitude angle pushbroom satellite remote sensing image and its ground point relation , strict orbital imaging model . The results show that the the article several generic model can produce high precision and stable orientation results . Established in the trial based on the orbital parameters of strict imaging model is correct , in the case of satellite remote sensing ground targeting , in particular, is the lack of ground control points , better application prospects .
