| 摘 要： | 用拍摄速度为60帧/s以上的CCD高速相机对光线示波器光点运动路径实时拍摄,在每一帧图像中获得激光光点在某一时刻所到达的位置。通过对图像进行平滑和灰度变换等图像处理,准确提取各幅图像中目标图像的位置坐标。将只含目标图像的多幅图像进行叠加处理,再将在一段时间内的各个离散的位置坐标拟合成激光光点完整的运动轨迹,进而揭示电信号的特征。

| Abstract: | The high speed charge coupled device （CCD） with 60 frame/second was adopted to abtain the optical oscillograph spot con- trail in real time in the system of electromagnetic oscillation. The positional information of the arrival of the laser spot at a given time was obtained through the processing of the images, and the coordinate position in each image was extracted exactly by image processing such as antialiasing, gray level transform, etc. So we can get the discrete coordinate position in a period of time and accomplish the depiction of the movement station of the spot of optical oscillograph to indicate the characteristics of the inputed electrical signal. |
