破片平均迎风面积测量方法的研究

METHODS FOR MEASURING THE AVERAGE FRONTAL AREA OF FRAGMENTS

对破片测量的作用及相关的理论进行了阐述，并对几种常用的破片平均迎风面积测量方法进行了介绍与分析，其中重点分析了一种新颖的破片平均迎风面积自动测量仪，它由照明系统、万向载物台、ＣＣＤ摄像机、控制和信号处理系统、图象处理与显示系统组成，集光、机、电、计算机等多种先进技术于一体，采用软、硬件相结合的方法，实现了对破片平均迎风面积的高精度、高速度的自动化测量．

The purpose and the principle of measuring frontal area of fragments are introduced. The methods of measurement are mentioned and discussed. A new instrumemt is described in details, which can finish the whole measuring process automatically. It is consisted of an illuminating system, a carrying stage, a CCD camera, a control system and an imageprocessing system. Several technologies are focused in it. It makes the highspeed and highprecision measuring of the frontal areas of fragments to be realized.
