To improve the image quality of aerial photography, image motion compensation technology has become a hot scientific technology, and the V/H of carrier aircraft is an important parameter of image motion compensation technology. This paper comprehensively describes a new method of the accurate measurement of V/H based on image matching, and this method use the image motion compensation formula reversely to measure the instantaneous V/H, realized the digital and miniaturization of the measurement. The relative error of this method can be reduced to 0.5%. The new method can effectively improve the accuracy of image motion compensation.
