一个点，正反转15度，3个点的拟合圆圆心

在VisionPro中，可以使用CogCaliper找到圆周上的三个点，并使用CogCircleFit找到这三个点的拟合圆心。下面是一个简单的示例程序，用于查找一个点，将其旋转15度，并找到其圆周上的三个点及其拟合圆心。

// 找圆周上的三个点

caliper.Region = circle;
caliper.Orientation = circularArc.AngleStart + Math.PI / 12;
caliper.RanParams.Edge0Position = 0.1 * circle.Radius;
caliper.RanParams.Edge1Position = 0.3 * circle.Radius;
caliper.Run();
double x1 = caliper.Edge0Position.X;
double y1 = caliper.Edge0Position.Y;
caliper.RanParams.Edge0Position = 0.4 * circle.Radius;
caliper.RanParams.Edge1Position = 0.6 * circle.Radius;

// 拟合圆
circle = new CogCircle(x1, y1, x2, y2, x3, y3);

// 输出结果
System.Console.WriteLine("Center: ({0}, {1})", circle.CenterX, circle.CenterY

// 读取图像
CogImage8Grey image = new CogImage8Grey();
image.Load("path/to/image.bmp");

// 创建拟合圆的工具
CogFitCircleTool fitCircle = new CogFitCircleTool();
fitCircle.InputImage = image;
fitCircle.Run();

// 获取拟合圆的圆心坐标
double centerX = fitCircle.Results.GetCircle().CenterX;
double centerY = fitCircle.Results.GetCircle().CenterY;

// 创建用于显示图形的容器
CogCompositeShape compositeShape = new CogCompositeShape();

// 创建圆心的十字线
CogLineSegment line1 = new CogLineSegment(centerX - 20, centerY, centerX + 20, centerY);
CogLineSegment line2 = new CogLineSegment(centerX, centerY - 20, centerX, centerY + 20);
line1.Color = CogColorConstants.Red;
line2.Color = CogColorConstants.Red;

// 将十字线添加到组合图形中
compositeShape.Add(line1, "");
compositeShape.Add(line2, "");

// 旋转点
double rotationAngle = 15; // 旋转角度
double pointX = centerX + 30; // 原始点的坐标
double pointY = centerY;
double radian = rotationAngle * Math.PI / 180; // 角度转弧度
double rotatedPointX = centerX + (pointX - centerX) * Math.Cos(radian) - (pointY - centerY) * Math.Sin(radian); // 旋转后点的X坐标
double rotatedPointY = centerY + (pointX - centerX) * Math.Sin(radian) + (pointY - centerY) * Math.Cos(radian); // 旋转后点的Y坐标

// 创建点的标记
CogGraphicLabel pointLabel = new CogGraphicLabel();
pointLabel.Color = CogColorConstants.Green;
pointLabel.Font = new Font("Arial", 10);
pointLabel.Text = "●";
pointLabel.SetXYText(rotatedPointX, rotatedPointY);

// 将标记添加到组合图形中
compositeShape.Add(pointLabel, "");

// 在图像上显示组合图形
CogDisplay cogDisplay = new CogDisplay();
cogDisplay.Image = image;
cogDisplay.StaticGraphics.Add(compositeShape, "");

// 显示图像
cogDisplay.Fit(true);
以上代码中，首先使用CogFitCircleTool类拟合一个圆，并获取拟合圆的圆心坐标。然后创建一个CogCompositeShape实例作为容器，将需要显示在图像上的图形（包括圆心的十字线和旋转后的点）添加到组合图形中。最后，在CogDisplay控件上显示图像和组合图形。

注意，CogCompositeShape的Add()方法的第二个参数是图形的名字，可以为空字符串。
