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

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
