1、脚本实现零件检测
零件边缘检测
按照图片所示使用部件,使用CogPatInspectTool框选零件检测区域,再对模板进行训练(注意训练模板所用的图像一定要是标准件)

使用脚本编写器,将以下代码添加到脚本中。
cs
//1.添加一个"图形"集合
CogGraphicCollection gc=new CogGraphicCollection();
//2.添加一个文本
CogGraphicLabel label = new CogGraphicLabel();
cs
CogBlobTool blob = mToolBlock.Tools["CogBlobTool1"] as CogBlobTool;
//对blob的结果数进行判断
if(blob.Results.GetBlobs().Count > 0)
{
label.SetXYText(200, 200, "NG");
label.Color = CogColorConstants.Red;
}
else
{
label.SetXYText(200, 200, "OK");
label.Color = CogColorConstants.Green;
}
gc.Clear();//清空集合
//向集合中添加文本标签
gc.Add(label);
//向集合中添加框选点
foreach(CogBlobResult a in blob.Results.GetBlobs())
{
//实例化每个斑点的边界
CogPolygon p = a.GetBoundary();
p.Color = CogColorConstants.Purple;//设置斑点边界颜色
gc.Add(p);//将斑点边界添加到集合中
}
cs
//将集合的内容显示到图层中
foreach( ICogGraphic c in gc)
{
mToolBlock.AddGraphicToRunRecord(c,lastRecord,"CogImageConvertTool1.InputImage","");
}
