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
