摘要
针对电磁推进装置外弹道高速电枢采集难的问题,文中设计了高速摄影采集系统对外弹道发射情况进行记录和分析,并成功的采集到电枢分别在低、高速下的序列图像。又创新性的运用ISODATA算法对采集图像进行分割处理获得比较精确的外弹道数据。通过实验对比,结果表明研究的处理算法简单易用,提高了参数测量的精度。
In view of difficult acquisition of high speed armature in electromagnetic propulsion device outside ballistic, in this paper, a high-speed photography collection system was designed for record and analysis under external ballistic firing conditions, and the armature image sequences were collected respectively under low and high speed successfully. ISODATA algorithm was used innovatively to segment the collected image for accurate trajectory data. Through experimental comparison, results show that the algorithm is simple and easy to use, improving the accuracy of parameter measurement.
