摘要

根据高速摄像系统在火箭弹离轨参数测量中的应用

介绍了火箭弹离轨参数测量原理

提出了帧相减、相关滤波定位、轴线自动提取等多种图像处理方法

并将这些方法应用于工程实际.实践表明

在利用帧相减和边缘跟踪技术进行粗定位的基础上

采用相关滤波技术在小区域进行定位可以减少计算量

使定位精度达到0.2个像元

而在轴线自动提取中

用灰度图像形态学边缘检测方法

可使姿态角测量精度优于0.5°.

Abstract

Using the application of high-speed photography for measurement of rocket′s initial trajectory parameters

the measurement principle of rockets' initial trajectory parameters is introduced

several image processing methods

such as inter-frame-correlation

correlation filter

axes auto-detection are proposed for engineering applications. Practical use shows that rough positioning by inter-frame-correlation and edge tracking + positioning in small zone by correlation filter can reduce computation work and reach a positioning accuracy of 0.2 pixel

and the use of edge detection for axes auto-detect may keep the attitude angle measurement accuracy better than 0.5°.
