Because of the poor geometrical location accuracy of the high resolution（HR） remote sensing imagery of CBERS-02B satellite which can not meet the requirements of some users,the article proposed the technology of block adjustment based on RPC model,and the block adjustment test has been done by using multiple HR remote sensing imagery,the results show that the method can effectively improve the geometric accuracy of remote sensing imagery.
