案例2:齿轮内径检测
1.使用模板匹配
2.设置匹配区域
3.使用掩膜不必要的干扰 （保留两个内径的圆形）
1.添加找圆工具
2.添加模板匹配中心坐标
3.给外圈圆添加找圆工具
RunParams.ExpectedCircularArc.CenterX
RunParams.ExpectedCircularArc.CenterY 找圆工具圆心坐标
因为我们模板匹配的是圆形 所引 匹配的圆形坐标 就是 找圆工具坐标
1.显示结果添加了 圆形图案 CogCircle circle

案例3：齿轮圆形到齿轮角距离检测 求出最大值最小值 平均值
1.模板匹配齿轮 目的：匹配整个齿轮特征
1.FixTure齿轮定位 后续提供定位参考
1.模板匹配单个齿轮角
2.设置查找概数 等其他参数 目的：匹配所有齿轮角特征
1.模板匹配单个齿轮角
1.卡尺工具 查找每个齿轮角的边线
2. 模板匹配每个卡尺坐标赋值给 卡尺工具的仿射矩形中心点坐标 Region.centerX Region.centerY 目的：为了给卡尺工具 提供坐标点参考
2.不要需要使用fixTure 原因：模板匹配2 提供坐标
1.找圆 目的：找到圆心坐标 用于后续点到点测量
1.点到点的距离测量工具
2.卡尺工具 Edge0.PositionX 和Edge0.PositionY 的坐标赋值给 点到点工具的 起点坐标
3.找圆工具的圆心坐标赋值给 点到点工具的 终点坐标
