Visionpro齿轮测量

效果展示

一、题目要求  求出最大值，最小值，平均值

二、分析 1.首先要进行模板匹配 2.划清匹配范围 3.匹配小三角的模板匹配 4.卡尺 5.用找圆工具  工具 1.CogPMAlignTool 2.CogCaliperTool 3.CogFindCircleTool 4.CogFixtureTool 三、模板匹配工具 1.搜索区域

2.齿轮匹配

3.设置参数

 4.卡尺设置

  5.找圆工具   四、代码分析 1.声明集合，文字显示工具，线段 CogGraphicCollection dt = new CogGraphicCollection(); CogGraphicLabel label; CogLineSegment line; 2.将工具进行实例化 dt.Clear(); CogPMAlignTool pma = mToolBlock.Tools["CogPMAlignTool2"]as CogPMAlignTool; CogCaliperTool caliper = mToolBlock.Tools["CogCaliperTool1"]as CogCaliperTool; CogFindCircleTool find = mToolBlock.Tools["CogFindCircleTool1"]as CogFindCircleTool; 3.解决实例化问题

4.声明List  弧度转角度（角度转弧度）遍历卡尺数量 公式：  弧度=角度/180*Math.PI              角度=弧度*180/MathPI List<double> distance = new List<double>(); for(int i = 0;i < pma.Results.Count;i++) { double angle = pma.Results[i].GetPose().Rotation * 180 / Math.PI; double rad = (angle - 90) / 180 * Math.PI; caliper.Region.CenterX = pma.Results[i].GetPose().TranslationX; caliper.Region.CenterY = pma.Results[i].GetPose().TranslationY; caliper.Region.Rotation = rad; caliper.Run();  5.卡尺找到的地方声明线段 line = new CogLineSegment(); line.SetStartEnd(find.Results.GetCircle().CenterX, find.Results.GetCircle().CenterY, caliper.Results[0].Edge0.PositionX, caliper.Results[0].Edge0.PositionY); line.LineWidthInScreenPixels = 1; line.Color = CogColorConstants.Red; dt.Add(line); 6.实例化点到点的距离工具 链接 CogDistancePointPointTool dis = new CogDistancePointPointTool(); dis.InputImage = mToolBlock.Inputs["OutputImage"].Value as CogImage8Grey; dis.StartX = find.Results.GetCircle().CenterX; dis.StartY = find.Results.GetCircle().CenterY; dis.EndX = caliper.Results[0].Edge0.PositionX; dis.EndY = caliper.Results[0].Edge0.PositionY; dis.Run(); distance.Add(dis.Distance); 7.放置每个角的长度位置 label = new CogGraphicLabel(); label.Font = new Font("楷体", 8); label.Color = CogColorConstants.Purple; label.SetXYText(caliper.Results[0].Edge0.PositionX, caliper.Results[0].Edge0.PositionY, dis.Distance.ToString("F2")); dt.Add(label); 五、找出最大，最小，平均值 double Max = 0; double Small = distance[0]; double total = 0; double average; for(int i = 0;i < distance.Count;i++) { if(distance[i] > Max) { Max = distance[i]; } if(distance[i] < Small) { Small = distance[i]; } total += distance[i]; } average = total / distance.Count; CogGraphicLabel label1 = new CogGraphicLabel(); CogGraphicLabel label2 = new CogGraphicLabel(); CogGraphicLabel label3 = new CogGraphicLabel(); label1.SetXYText(100, 100, "最大值是:" + Max.ToString("F2")); label2.SetXYText(100, 130, "最小值是:" + Small.ToString("F2")); label3.SetXYText(100, 160, "平均值是:" + average.ToString("F2")); label1.Color = CogColorConstants.Red; label1.Font = new Font("楷体", 20); label2.Color = CogColorConstants.Red; label2.Font = new Font("楷体", 20); label3.Color = CogColorConstants.Red; label3.Font = new Font("楷体", 20); dt.Add(label1); dt.Add(label2); dt.Add(label3); 六、实现在图片工具图上 foreach(ICogGraphic s in dt) { mToolBlock.AddGraphicToRunRecord(s, lastRecord, "CogPMAlignTool1.InputImage", ""); } 七、愚公搬代码 #region namespace imports using System; using System.Collections;
