调用方法
std::vector<cv::Point2f> inputDistortedPoints = ...
std::vector<cv::Point2f> outputUndistortedPoints;
cv::Mat cameraMatrix = ...
cv::Mat distCoeffs = ...
cv::undistortPoints(inputDistortedPoints, outputUndistortedPoints, cameraMatrix, distCoeffs, cv::noArray(), cameraMatrix);
不要像下面这样调用,输出的点不正确
cv::undistortPoints(inputDistortedPoints, outputUndistortedPoints, cameraMatrix, distCoeffs)
UPDATE:
Following C++ function call should work as well:
std::vector<cv::Point2f> inputDistortedPoints = ...
std::vector<cv::Point2f> outputUndistortedPoints;
cv::Mat cameraMatrix = ...
cv::Mat distCoeffs = ...
cv::undistortPoints(inputDistortedPoints, outputUndistortedPoints, cameraMatrix, distCoeffs, cv::noArray(), cameraMatrix);
