我尝试使用fillConvexPoly函数填充蒙版中的三角形。
但是我收到以下错误。
OpenCV Error: Assertion failed (points.checkVector(2, CV_32S) >= 0) in fillConvexPoly, file /home/iris/Downloads/opencv-3.1.0/modules/imgproc/src/drawing.cpp, line 2256
terminate called after throwing an instance of 'cv::Exception'
what(): /home/iris/Downloads/opencv-3.1.0/modules/imgproc/src/drawing.cpp:2256: error: (-215) points.checkVector(2, CV_32S) >= 0 in function fillConvexPoly
我像这样调用函数，
cv::Mat mask = cv::Mat::zeros(r2.size(), CV_32FC3);
cv::fillConvexPoly(mask, trOutCroppedInt, cv::Scalar(1.0, 1.0, 1.0), 16, 0);
其中trOutCroppedInt定义如此，
std::vector<cv::Point> trOutCroppedInt
我在矢量中推了3个点，
[83, 46; 0, 48; 39, 0]
我该如何更正此错误？
