A new method is proposed to detect the edge through modulating scanning laser beam and picking up the phase reversal of the detection signal as the edge signal.

讨论了一种新的边缘检测方法，即对扫描激光束进行调制，并利用调制信号的相位突变提取边缘信号。

It analyses and studies the operating method in image processing area, including image division, image filter, picking up edge point, drawing up line and getting the distance of parallel lines.

分析并研究了可用于指针图像处理的图像分割、图像滤波、边缘点提取、直线拟合、平行直线求距等运算方法。
