摘要

在高射频武器和多管武器弹丸着靶坐标测量当中，偶而会发生两发弹丸、破片等被测目标同时着靶的情况，为了克服传统弹丸着靶坐标测量方法不能测量双目标同时着靶的问题，设计了一种采用基于单台黑白线阵CCD相机配合一台一字线激光器，以及投影板等部件组成的单线阵CCD立靶测量系统。本文对单线阵CCD立靶测量系统捕获的双目标信号进行理论分析和实际处理，根据弹丸信号灰度值和所占CCD器件像元宽度值两种信号特征的不同，对3种不同类型的双目标信号进行了识别。模拟实弹验证实验结果显示：测量误差在靶面为0.5 m×1 m时，

Abstract

Currently several coordinate measurement methods for bullets to impact could not be used in the situation for two bullets to impact simultaneously

thus CCD vertical target measurement system of single linear array composed of components such as a CCD camera based on single black-and-white linear array

a double hyphen line laser and projection plank

etc was adopted to overcome the problem that measurement for double objectives to impact could not be achieved in traditional coordinate measurement method for bullets to impact. Theoretical analysis and actual handling were conducted on signal of double objectives captured by CCD vertical measurement system of single linear array and recognition was conducted on three different types of signals of double objectives according to two different signal feature including grey value of bullet signal and pixel width value of occupied CCD device. Feasibility and measurement precision of the system were verified through the method to simulate live ammunition verification and feasibility of signal handling method of double objectives was proved; standard deviations and of measurement error of coordinate

and coordinate

are respectively 2.0 mm and 6.8 mm when target surface is 0.5 m×1 m.
