Paper Abstract

The main method of the attitude measurement is to get series of graphs for analyzing the changing attitude of the projectile by utilizing multiple shadowgraph-taking camera stations.However,the premise of accurate results is that feature points on graphs must match its spatial coordinate in a certain spatial coordinate.Addressing to this problem,combining the optical lever principle and the PSD,we propose a method of calibrating the spatial coordinate coherence of the long distance and multiple shadowgraph-taking camera stations,and analyze the measurement accuracy and repeatability of this method.According to the results,the accuracy of this calibration method is superior to 0.1mm .
