靶丸目标图象预处理

The Image Preprocessing for Pellet Target

主要阐述了提取ＩＣＦ实验中靶丸目标边缘轮廓的图象处理方法。包括Ｓｏｂｅｌ边缘检测算子在内的多种方法都能够检测目标物体边缘，但未改进的算法在实验中效果不是很好。根据实验要求，本文提出采用基于图象信息熵的阈值选取算法和八方向Ｓｏｂｅｌ边缘算子相结合的边缘检测方法。

An image processing method for extracting edge profile image of the pellet target in the inertial confinement fusion experiments is described in the paper.The target edge can be detected by many methods including Sobel edge detection operator,but effect of the unmodified algorithms are not very well in the experiments.An edge detection method using the combination of threshold selecting algorithm based on image information entropy and eight direction Sobel edge operator is proposed in the paper according to the experimental requirements.The processed results have attained the experimental requirements.
