Gun Aiming Equivalence and Shooting Efficiency Autocorrection before Delivery

doi:10.12382/bgxb.2021.0607

Abstract

Abstract: A method of gun aiming equivalence and shooting efficiency autocorrection of firearms is proposed to replace the traditional pre-delivery shooting correction process mainly based on live-shot tests. Based on optical principles and an image recognition method, an equivalent space model for launching line and aiming baseline is established with factors such as matching errors considered. Based on the external ballistic characteristics and relative position errors, a mathematical model for mechanical aiming adjustment is established. Input photoelectric detection and signal exclusion processing are used to calculate the equivalent beam signal set and then obtain the calibration parameters. A set of autocorrection device and software system for shooting efficiency has been developed. Test results show that the autocorrection method is effective and feasible to meet the shooting accuracy requirements before delivery.

Key words: gunshootingeffectcorrection, equivalentmethod, errorcompensation, autocorrection
