Abstract

Abstract: In order to accurately measure the space electric connector of the separation distance, for further study of its separation characteristics, a high-speed photography environment oriented electrical connector on the edge of the separation extraction method was presented herein. Mainly through the algorithm divided the region of interest area selected for measuring positions, after processing through the filter, wavelet transform to enhance image edge of weak signals, and then through the two adaptive threshold segmentation of image, and by using SUSAN operator for edge detection, and then the edge was extracted, the accurate edge informations were obtained.

摘要： 为了准确测量航天电连接器的分离距离，以深入研究其分离特性，提出了一种高速摄像环境下电连接器分离边缘的提取算法。该算法主要通过划分感兴趣区域选定待测量位置区域，经滤波处理后，利用小波变换算法增强图像的弱边缘信号，然后通过两次自适应阈值分割图像，并利用SUSAN算子进行边缘检测，进而提取边缘，获得准确的边缘信息。
