The dynamic performance of weapons and equipment is one of the important technical indicators of the appraisal system of the shooting range and the type test evaluation system. At present, high-speed rotary artillery and weapons are new modern weapons; a qualified barrel weapon needs to be tested for dynamic performance before it is put into use. , the deviation angle between the actual direction of the closed barrel at the scheduled firing moment and the predetermined firing direction is an important technical indicator for testing the dynamic performance of the barrel weapon. The test problem of the pointing accuracy and stability of the tube is proposed; a measurement method using laser prism aiming and spot image processing is proposed to solve this problem; the test principle and structural composition of the barrel pointing of this method are introduced in detail. The mathematical model pointed to, and the measurement principle of the structure was analyzed in depth. After building a simulated experimental device and conducting experiments, after analyzing the experimental data, the experimental error range was calculated to be within 3%, which proved the feasibility of the method.
