When i run the following program it is working but when i run it in fedora it shows the error message
OpenCV Error: Assertion failed (k == STD_VECTOR_MAT) in getMat, file /builddir/build/BUILD/OpenCV-2.3.1/modules/core/src/matrix.cpp, line 918
terminate called after throwing an instance of 'cv::Exception'
what(): /builddir/build/BUILD/OpenCV-2.3.1/modules/core/src/matrix.cpp:918: error: (-215) k == STD_VECTOR_MAT in function getMat
Mainly this error is thrown when the getPerspectiveTransform(P,Q); is included.
the code is
#include "opencv2/opencv.hpp"
using namespace cv;
int main()
{
Mat ocv = imread("chess.png");
vector<Point2f> P,Q;
P.push_back(Point2f(118,128));
Q.push_back(Point2f(10,10)); // 10 pixel border on all sides
P.push_back(Point2f(753,19));
Q.push_back(Point2f(210,10));
P.push_back(Point2f(625,328));
Q.push_back(Point2f(210,210));
P.push_back(Point2f(18,542));
Q.push_back(Point2f(10,210));
Mat rot = cv::getPerspectiveTransform(P,Q);
Mat result;
cv::warpPerspective(ocv, result, rot, Size(220,220));
imshow("result",result);
waitKey();
return 0;
}
Why this error occoured?
