摘　　要：针对激光扫平仪光电自动检测系统中扫描激光线图像处理的实际情况 ,先采用隔行中值滤波来对图像进行预处理。然后 ,结合图像采集卡动态采集图像的特点 ,在分析扫描线区域的灰度值的基础上 ,提出根据图像采集卡奇、偶场采集结果的不同来对图像进行二值化处理的方法 ,实现了对扫描激光线图像的自动处理 ,获得了满意的效果。Considering the image process practice of scanning laser line in the automatic photoelectric detecting system for the laser swinger,the interleaved median filtering is taken up to preprocess the image.Then combining the characteristic of grabbing image dynamically,a new technique has brought forward to process the image on basic of image different of parity field by image frame grabber after analyzing the gray of the region of scanning laser line.In this way,we can process the scanning laser line automatically and achieve a satisfying result in accord with the need of production testing precision.
