枪械出厂前瞄准等效及其射效自动校正方法

为改变传统以实弹试射为主的枪械出厂前射效校正，提出一种枪械瞄准等效及枪械射效自动校正的方法。基于光学原理和图像识别方法，考虑配合误差等因素建立了射线及瞄准基线的等效空间模型；综合外弹道特性以及相对位置误差的影响，建立了机械瞄具校调数学模型，输入光电检测及信号排异处理得到的等效光束信号集，计算获得校调参数；开发了一套枪械射效自动校正装置和软件系统。通过试验验证表明，枪械瞄准等效和射效自动校正方法有效、可行，可以满足枪械出厂前射击精度要求下机械瞄具的自动化校正要求。

Gun Aiming Equivalence and Shooting Efficiency Autocorrection before Delivery

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.
