Three-line array CCD imagery self-calibration block adjustment based on equivalent error equations

WANG Tao,ZHANG Yan,RUI Jie,PAN Shen-lin(Institute of Surveying and Mapping,Information Engineering University,Zhengzhou 450052,China)  
For self-block adjustment of airborne three-line array CCD ADS40 imagery,there exist difficulties of large number unknown parameters,huge and complex equation,enormous memory occupation and slow problem solving.Aiming at solving these problems,one ADS40 imagery self-block adjustment approach based on equivalent error equation was proposed in the paper.Through the use of the virtual error equation method,the original error equation was changed and transformed to build the equivalent error equation for the self-block adjustment of ADS40 imagery,which would eliminate the ground coordinate corrections of photogrammetric control points,and greatly reduce the number of unknowns,and rationally simplify the structure of the normal equation.Experimental results proved that taking the equivalent error equation approach in the self-block adjustment could effectively reduce the memory allocation and occupation,significantly improve computation efficiency,while ensuring the accuracy of the block adjustment.
