实现简单的灰度处理,主要调用BItmap函数库的内容，实现位处理功能。-This system mainly uses LabWindows/CVI and the visual software package Vision design system program. Vision has a wide range of machine vision development environment, the visual software package Vision machine vision algorithm contains all kinds of filtering, mathematical transformation, morphological analysis, calibration, classification identification, shape search and other basic computing functions. Process is as follows: image acquisition, gray processing, image segmentation, filtering denoising, computing area.
