Hi,
I'm trying to use the fisheye functions to produce an undistorted image from a fisheye (ftheta lens) camera. When I do: fisheye::calibrate fisheye::estimateNewCameraMatrixForUndistortRectify fisheye::initUndistortRectifyMap cv::remap cv::imwrite All I get is a black image. It seems that the maps I get in initUndistortRectifyMap are wrong - even when I don't actually run fisheye::calibrate and I set all the distortion coefficients to zero. When I use a rectilinear model, i.e., when I do cv::calibrateCamera cv::initUndistortRectifyMap cv::remap cv::imwrite I get a correct image. Of course the correction is not ideal - as you can expect when applying this to a fisheye camera.
Are there some known issues in function initUndistortRectifyMap? I'm using version 2.4.10. Are there some changes/fixes in version 3.0? Thanks,
Thom
