摘要:With the development of space technology, space photogrammetry is becoming a direction of photogrammetry. Satellitic linear array scanner imagery, as chief space imagery, is used increasingly. It is used widely in geospatial data production and updating. Because linear array scanner imagery is dynamic, its exterior orientation elements change along with the movement of satellite and normal equation that we use when its exterior orientation elements are computed is ill-conditioned. First, this paper analyses previous methods of solving this problem. Then, generalized ridge estimate is presented to do it. The method of educing the parameters of generalized ridge estimate is explained in the end. Experiments evince this method is very simple, steady and effective
