MIL边缘检查实战1.0 20220303

一、边缘检查常用方法

二、MIL自带Tools Matrox Edge Finder操作

三、程序逻辑

四、程序代码

一、边缘检查常用方法

MgraAllocList	分配一个图像列表
MedgeAlloc	分配边缘检查器
MedgeAllocResult	分配边缘检测数据
MedgeControl	控制边缘检查设置
MedgeCalculate	执行边缘提取和特征计算
MedgeGetResult	从边缘结果缓冲区获取边的结果
MedgeSelect	选择边进行计算和结果检索

二、MIL自带Tools Matrox Edge Finder操作

1）选择Matrox Edge Finder

2)点击File→OPEN（选择图像）

3）点击File→New Edge Finder→Contour Edge Finder

4)点击Calculate计算，显示边缘

5）在Contour Edge Finder中有Feature Selections，其中有相关参数查看，在本次边缘检查中，需要Moment Elongation参数参考

三、程序逻辑

四、程序代码

1)控制台代码
