Aim To explore how to improve the accuracy of line CCD camera intersection measurement and to analyze the principle of CCD camera intersection measurement.Methods Real-time acquisition of the target miss distance of projectile target was achieved by using virtual target instead of physical target.Results and Conclusions After analyzing the factors that affect the accuracy of the intersection measurement, such as the angle accuracy of the CCD camera and the method of distributing the stations, the results of the CCD camera coordinate measurement at different points on the photoelectric target are calculated. Finally, the measurement accuracy and the cloth Station relationship.CCD camera axis orthogonal system has the highest measurement accuracy.
