【机械视觉】C#+VisionPro联合编程———【四、检测彩色保险丝实例，以及C#+VisionPro的两种写法】
在机械视觉C#+VisionPro联合编程编程中，在处理业务逻辑时通常会有两种写法，一种是将逻辑代码编写在visionPro中然后再使用C#将visionPro工具加载到vs中，另一种是先通过C#加载visionPro工具到vs中再使用C#在vs中编写逻辑代码。
本篇文章将用检测彩色保险丝的实例将这两种写法分别展现出来。
实例一写法(在vs中编写逻辑代码)
所用的winform工具:
- button
- label
- cogRecordDisplay
实现逻辑
此案例用的是复合颜色匹配工具CogCompositeColorMatchTool和CogPMAlignTool，用了脚本实现，功能更加强大，这个借用的脚本能实现多个颜色数量一起显示。
先将复合颜色匹配工具训练各个颜色数据，将PMA匹配到的每个保险丝，然后保存工具。
在vs中加载复合颜色匹配工具和PMA工具，将PMA匹配到的每个保险丝位置信息传给复合颜色匹配工具，然后在代码中运行此工具，将匹配得到的颜色数量存储在一个变量中，最后再用label进行显示。
第一步、训练复合颜色匹配工具和PMA工具(并且保存)
第二步、将工具加载到vs中
Pma = (CogPMAlignTool)CogSerializer.LoadObjectFromFile("./pma.vpp");
Col = (CogCompositeColorMatchTool)CogSerializer.LoadObjectFromFile("./col.vpp");第三步、将PMA匹配到的每个保险丝位置信息传给复合颜色匹配工具，然后在代码中运行此工具，获取匹配结果并将结果展示在label
for (int i = 0; i < Pma.Results.Count; i++)
{CogCircle cir = Col.Region as CogCircle;cir.CenterX = Pma.Results[i].GetPose().TranslationX;cir.CenterY = Pma.Results[i].GetPose().TranslationY;Col.Region = cir;Col.Run();string name = Col.Result.ResultOfBestMatch.Color.Name;switch (name){case "red":dic["红色"] = dic["红色"] += 1;break;case "blue":dic["蓝色"] = dic["蓝色"] += 1;break;case "green":dic["绿色"] = dic["绿色"] += 1;break;case "orange":dic["橙色"] = dic["橙色"] += 1;break;case "yellow":dic["黄色"] = dic["黄色"] += 1;break;}}this.label1.Text = $"红色:{dic["红色"]}, 蓝色: {dic["蓝色"]}, 绿色: {dic["绿色"]}, 橙色: {dic["橙色"]}, 黄色: {dic["黄色"]}";完整代码

所用的winform工具:
- button
- label
- cogRecordDisplay
实现逻辑
先在visionPro中添加toolblock工具并在工具中训练复合颜色和pma匹配工具，然后使用toolblock工具中的C# Advanced Script脚本编写逻辑代码，将PMA匹配到的每个保险丝位置信息传给复合颜色匹配工具，然后在代码中运行此工具，将匹配结果进行展现。
将工具保存到本地，然后使用C#在vs中加载，将匹配结果展现在winform中。
