opencv - 错误CS0119:表达式表示为 `type'，其中应为 `variable'， `value'或 `method group'

Question

public Point[] calc_peaks (Mat im,
                   Point[] points,
                   OpenCvSharp.CvSize ssize)
    {
            int n = points.Length;
            Mat matpoints = OpenCvSharp.CPlusPlus.MatOfPoint2f (points);
            using (Mat pt = (new MatOfPoint2f (matpoints)).Reshape (1, 2 * n))

我在Unity上尝试了此代码，它说在Cs0119错误:

Mat matpoints = OpenCvSharp.CPlusPlus.MatOfPoint2f (points) 

它让我发疯了!我试图删除错误行;但是它说:

error CS1503: Argument #1' cannot convert OpenCvSharp.CPlusPlus.Point[] expression to type System.IntPtr

Answer 1

可以肯定的问题是MatOfPoint2f()需要一个Point，但是您给它一个Points数组
