A method for measuring the penetration angle of oblique projectile was proposed based on high-speed photography and digital image analysis. Using median filter, threshold segmentation and temporal differencing image processing methods, the penetration angle was automatically obtained through VC programming. The simulation experiment results show that the method can calculate the penetration angle availably and accurately.
