dIrX 过滤X方向点的间距差值 private static List<Point2f> FilterPoints(Mat resultImage, List<Point2f> points, double tolerance，bool dIrX) { var filteredPoints = new List<Point2f>(); foreach (var currentPoint in points) { bool isUnique = points .Where(p => p != currentPoint) .All(comparePoint => ((currentPoint.X - comparePoint.X) * (currentPoint.X - comparePoint.X) + (currentPoint.Y - comparePoint.Y) * (currentPoint.Y - comparePoint.Y)) >= tolerance * tolerance); if (isUnique) { filteredPoints.Add(currentPoint); drawCross(resultImage, new Point2f(currentPoint.X , currentPoint.Y ), Scalar.Red, 5, 1); } } return filteredPoints; } 基于opencvsharp4.5编写c#代码,生成新的函数

可以考虑编写一个类似于上述代码的函数，以实现在Y方向上过滤点的间距差值。代码如下：

private static List<Point2f> FilterPointsY(Mat resultImage, List<Point2f> points, double tolerance)
{
    var filteredPoints = new List<Point2f>();
    foreach (var currentPoint in points)
    {
        bool isUnique = points
            .Where(p => p != currentPoint)
            .All(comparePoint => ((currentPoint.X - comparePoint.X) * (currentPoint.X - comparePoint.X) + (currentPoint.Y - comparePoint.Y) * (currentPoint.Y - comparePoint.Y)) >= tolerance * tolerance);
        if (isUnique)
        {
            filteredPoints.Add(currentPoint);
            drawCross(resultImage, new Point2f(currentPoint.X, currentPoint.Y), Scalar.Red, 5, 1);
        }
    }
    return filteredPoints;
}

该函数的作用是对输入的点集进行过滤，仅保留Y方向上间距大于等于指定容差值的点。其中，参数`points`表示输入的点集，`tolerance`表示容差值，`resultImage`表示需要在其上绘制筛选后的点的图像。函数返回经过过滤后的点集。
