【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

https://i-blog.csdnimg.cn/direct/dab07a3ce44140daa197e1625660efe4.png

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)

https://i-blog.csdnimg.cn/direct/92e2f3a3a55b4a738b35b2fa4d77e34e.png

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"]}";

实例二写法(在visionPro中编写逻辑代码)

所用的winform工具:

  • button
  • label
  • cogRecordDisplay

https://i-blog.csdnimg.cn/direct/8d9ba92ccb804ffebe3ffcec9e5f640f.png

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。

第一步、在toolblock中训练复合颜色匹配工具和PMA工具
