Based on the working principle, characteristics and technical indicators of low-altitude and low-velocity ammunition, taking a certain type of anti-terrorism ammunition as the research object and high-speed camera as the main test instrument, a high-precision and low-cost test method is obtained through the design of lens depth of field, pixel calibration, time unification and total station optimization, which is proved to be accurate and reliable by the target test. The results show that the test method can provide test data support for exterior ballistic optimization design of low altitude and low velocity ammunition.
