?2.案例：网格缺陷检测

1.使用IPoneimage 预处理图片工具? 调整图形的整体对比度 使用blob时 更能清楚的辨别特征

2.侵蚀正方体? 使blob 白底区域减少? 继续优化匹配结果

1.过滤周长 0-200

?3.

1.彩色图像中提取像素来创建灰度图像

2.对于所有黄色胶囊进行颜色提取? 目的:为了得到黄色区域的灰度图

、

1.经过提取后得到的灰度图? 但是 灰度图中 胶囊因为有光照影响? 出现了不同大小的黑色斑点?

1.为了减少 黑色斑点带来的blob匹配难度??? 使用CogIPOneImageTool? 来预处理图形?

2.使用灰阶形态NxM?

3.调整内核宽高

4.调整后图像

?

1.使用blob设置参数

1.过滤 干扰 特征

?4.糖果检测? 和? 1 案例 基本一致?

区别

案例1 使用时 pma? 配合 CogRectangleAffine 矩形限定框? 来进行CogCompositeColorMatchTool 颜色匹配工具 区域的划分

案例4? 使用blob 配合CogCircle 圆心图形 来进行CogCompositeColorMatchTool 颜色匹配工具 区域的划分

1.在block开头加了 一个CogIPoneImageTool? 目的:为了 后续图形 需要 图像预处理时 备用
