The angle systems of INS used in low -altitude remote sensing platforms is often different from that of elements of exterior orientation in photogrammetry , conversion and correction work are needed .The paper analyzes the relationship between the two angle systems and derives a mathematical formula for their easy transformation .Group experiments are designed , and results prove that the proposed method is feasible and effective , and it can improve the effect of image pre -processing obviously .
