线序识别；通过线的颜色来判断线序颜色并标注颜色

1. 二值图转换

2.模板匹配

3.定位工具

4.使用色彩匹配工具对每个位置的线都进行匹配一共需要7个工具

1.提取7中色彩

2.对于每个线分别进行区域检测

案例：注胶有无识别：判断图中产品周边槽及中心孔内注胶有无。蓝色为有胶，黑色为无胶并标注颜色

1.添加提取颜色工具

2.对有胶的图片进行颜色提取

3.依据获得的像素值（如果是0 就是无胶）

密封条胶塞颜色识别:识别图中出现的密封条胶塞的颜色，并标注颜色

1.使用颜色提取工具对每张图中的不同颜色的密封胶条提取色彩

2.使用blob工具提取结果如果能提取出结果说明有对应颜色密封胶条

1.哪个blob中有结果证明颜色存在
