Accurate extraction of target missile plays a vital role in the TV—guided process of goniometer. In recent years, the rapid development of machine vision technology provides a new way of thinking for identification of the target missile. This paper established frame of target missile recognition system, followed by processing the collected images such as image preprocessing, image segmentation, playing standard determined, playing standard calculation, finally got target missile in digital image coordinates. Mading a comparative study of the image processing algorithm in several aspects, and the algorithm got selected through experiment results. Steps and the basis for judgment of target missile is proposed according to its characteristics. The results show that the recognition system can accurately, effectively extract target missile signal.%弹标的精确提取在电视测角仪制导的过程中起着至关重要的作用,近年来机器视觉技术的迅速发展为弹标的识别提供了一种新的思路;首先建立了弹标识别系统的框架,依次对采集图像进行图像预处理、图像分割、弹标判定、弹标计算,最终得到了弹标在数字图像中的坐标;研究比较了各环节图像处理算法,并通过实验结果对算法进行选定.根据弹标的特征提出了弹标判定的步骤和依据;实验结果表明,弹标识别系统能精确、有效地提取出弹标信号.
