Revision history [back]

Hi community,

I was just tracking the samples shipped with OpenCV created the disparity map for the aloe plant but cannot reproject3d as i cannot find the extrinsics file in the samples directory. I know this is a loser question :) maybe someone can point out a better example data set?

Thank you very much!

Hi community,

I was just tracking the samples shipped with OpenCV created the disparity map for the aloe plant but cannot reproject3d as i cannot find the extrinsics file in the samples directory. I know this is a loser question :) maybe someone can point out a better example data set?

The example file is ; /opencv\sources\samples\cpp\stereo_match.cpp

..but this is a console program and expects the file names as the parameters which i do not know where to get. I'm assuming the right intrinsics file is the 'intrinsics.yml' file found in /opencv\sources\samples\data, but it is impossible without having the extrinsics to reproject3d. The disparity map settings is as follows for those who might be interested:

sStereo->alg = StereoCameraRig::STEREO_SGBM;
  sStereo->SADWindowSize = 11;
  sStereo->numberOfDisparities = 192;
  sStereo->preFilterCap = 4;
  sStereo->minDisparity = -64;
  sStereo->uniquenessRatio = 1;
  sStereo->speckleWindowSize = 150;
  sStereo->speckleRange = 1;
  sStereo->disp12MaxDiff = 1;
  sStereo->P1 = 600;
  sStereo->P2 = 2400;
  sStereo->textureThreshold = 500;

  stRig.CreateUpdateStereoMatcher();

  stRig.getDisparityMap(viewL, viewR, dispMap, false);

  normalize(dispMap, disp8, 0, 255, CV_MINMAX, CV_8U);

  showImage(disp8, true);

Thank you very much!
