机器视觉就是用机器代替人眼来做测量和判断。机器视觉系统是指通过机器视觉产品(即图像摄取装置,分CMOS和CCD两种)将被摄取目标转换成图像信号,传送给专用的图像处理系统,根据像素分布和亮度、颜色等信息,转变成数字化信号;图像系统对这些信号进行各种运算来抽取目标的特征,进而根据判别的结果来控制现场的设备动作。
Machine vision is the machine to replace the human eye to make measurements and judgments. Machine vision system refers to the machine vision products (ie image capture device, sub-CMOS and CCD two) will be taken into the target image signal is transmitted to a dedicated image processing system, according to the pixel distribution and brightness, color and other information, change Into a digitized signal; the image system performs various operations on these signals to extract the characteristics of the target, and then controls the on-site device actions according to the result of the discrimination.
