电磁振荡系统激光点信息提取及轨迹叠加程序处理

Program processing of the superposition and extraction of the laser spot contrail in the system of electromagnetic oscillation

对于电磁振荡系统,采用拍摄速度为60帧/秒以上的CCD高速相机对激光光点运动路径的实时拍摄,通过对所获图像集的处理,可以得到每一帧图像中参考光点在某一时刻所到达的位置信息,通过对图像进行图像平滑和灰度变换等图像处理,可以准确提取各幅图像中目标图像的位置坐标,然后将只含目标图像的多幅图像进行叠加处理,进而获取在一段时间内的各个离散的位置坐标,最后采用多项式拟合完成对振荡系统运动状态的刻画,以实现对振荡系统相关物理量的测试。

The high speed CCD with 60 frame/second is adopted to obtain the laser spot contrail in re- al time in the system of electromagnetic oscillation. The positional information of the arrival of the laser spot at a a given time was obtained through the processing of the imagesets, and the coordinate posi- tion in each image is been extracted exactly by image processing such as antialiasing, gray level trans- form and so on. So we can get the discrete coordinate position of the laser spot contrail in a period of time by superposition of the imagesets, and accomplish measuring the related physical quantity by the depiction of the movement station of the system of electromagnetic oscillation.
