快速视频判读方法的研究

Method of fast video interpretation

视频判读仪是现代靶场光测设备重要组成部分。为了提高视频判读的效率 ,本文研究了新型的快速判读方法 ,包括自动判读和半自动判读。自动判读把存储于计算机硬盘中图像经过中值滤波以及二值化分割后 ,自动计算目标的重心位置 ,输出脱靶量 ;而对于大目标、低对比度等特殊情况下 ,自动判读精度较低 ,用人工半自动判读方法进行处理 ,提高判读精度。这种采用自动判读与人工半自动判读相结合的判读方法 ,极大地提高判读效率和准确性。

WT5BZ]The video interpretation is an important component of modern optical measurement equipment. In order to increase the efficiency of video interpretation, a new and quick interpretation method, including automatic interpretation and semiautomatic interpretation, is studied and presented. In automatic interpretation, the image stored in hard disk of computer is decomposed through median filtering and two value segmentation, and the barycenter of target is automatically computed, then the output of target undershoot error is given. However, under the special conditions of large target and low contrast, the precision of automatic interpretation is relatively low, it is necessary to use semiautomatic interpretation method to improve the interpretation precision. The experiment results in this thesis show that the hybrid of automatic interpretation and semiautomatic interpretation as a new interpretation method can greatly increase the efficiency and precision of interpretation.
