| Abstract: | Starting from forward intersection formula,a formula of the precision estimation was developed for the three-line-array CCD imagery without ground control points.This can be used in the space photography system engineering for evaluating some guidelines.The precision estimation was done using the simulation datum,and then the relation between the precision of camera station and pose were pointed.At last the settle project was put forward for mapping of 1∶50 000 scale. |
