CogPMAligMultiTool 工具使用-发卡识别

需求

识别下列发卡的形状

工具使用

1.脚本灰度值转换的引用

2.添加转灰度值脚本

CogImageConvertTool image = new CogImageConvertTool(); image.InputImage = mToolBlock.Inputs["InputImage"].Value as ICogImage; image.RunParams.RunMode = CogImageConvertRunModeConstants.Intensity; image.Run();

3.将转换后图像赋值

CogPMAlignMultiTool pma = mToolBlock.Tools["CogPMAlignMultiTool1"]as CogPMAlignMultiTool; pma.InputImage = image.OutputImage; pma.Run();

4.CogPMAlignMultiTool 工具实操

5.创建label集合和类

private CogGraphicCollection dt = new CogGraphicCollection(); dt.Clear(); private CogGraphicLabel createlabel(string text, float size, double x, double y, CogColorConstants color) { CogGraphicLabel label = new CogGraphicLabel(); label.Alignment = CogGraphicLabelAlignmentConstants.TopLeft; label.BackgroundColor = CogColorConstants.White; label.Color = color; label.Font = new Font("Arial", size, FontStyle.Bold, GraphicsUnit.Pixel); label.SetXYText(x, y, text); return label; }

6.遍历CogPMAlignMultiTool 并赋值

string type = ""; for(int i = 0;i < pma.Results.ResultItemCollection.Count;i++) { switch(pma.Results.ResultItemCollection[i].Name) { case"青蛙": type = "青蛙"; break; case"笑脸": type = "笑脸"; break; case"爱心": type = "爱心"; break; } dt.Add(createlabel("类型是:" + type, 25, 10, 10, CogColorConstants.Blue)); dt.Add(createlabel(DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"), 25, 10, 90, CogColorConstants.Green)); }

7.赋值展示图片

foreach(ICogGraphic s in dt) { mToolBlock.AddGraphicToRunRecord(s, lastRecord, "CogPMAlignMultiTool1.InputImage", "script"); }

8.脚本All
