求教大神 透视变换函数getPerspectiveTransform的调用问题

[冷若寒阳s]

vector<Point2f> origin_corner;
origin_corner.push_back(Point2f(xMin, yMin));
origin_corner.push_back(Point2f(xMin, yMax));
origin_corner.push_back(Point2f(xMax, yMin));
origin_corner.push_back(Point2f(xMax, yMax));

vector<Point2f> after_corner;
after_corner.push_back(Point2f(0, 0));
after_corner.push_back(Point2f(0, yMax - yMin));
after_corner.push_back(Point2f(xMax - xMin, 0));
after_corner.push_back(Point2f(xMax - xMin, yMax - yMin));

Mat transMatrix = getPerspectiveTransform(origin_corner, after_corner);

总是显示输入参数不对 和其他人一样的程序 Assertion failed ：src.checkVector<2, CV_32F> == 4 && dst.checkVector<2, CV_32F> == 4

这句话条件不满足：

[penghuahuijuan]

src.checkVector<2, CV_32F> == 4 && dst.checkVector<2, CV_32F> == 4，条件不满足； 你看看这个就明白了：http://www.cnblogs.com/tornadomeet/archive/2012/11/04/2753185.html 将4变为通道数和元素个数的乘积，应该就正确了

我顶。。。。
