Detailed Description

Use this class to rectify stereo images if the same distortion maps are reused over and over again.

The rectify maps are cached internally and only computed once for the camera parameters. The stereo camera calibration must be supplied in a mrpt::util::TStereoCamera structure (which provides method for loading from a plain text config file) or directly from the parameters of a mrpt::obs::CObservationStereoImages object.

Remember that the rectified images have a different set of intrinsic parameters than the original images, which can be retrieved with getRectifiedImageParams()

Works with grayscale or color images.

Refer to the program stereo-calib-gui for a tool that generates the required stereo camera parameters from a set of stereo images of a checkerboard.

Example of usage with mrpt::obs::CObservationStereoImages:

   CStereoRectifyMap   rectify_map;
   // Set options as desired:
   // rectify_map.setAlpha(...);
   // rectify_map.enableBothCentersCoincide(...);
   while (true) {
     mrpt::obs::CObservationStereoImages::Ptr obs_stereo = ... // Grab stereo
observation from wherever
     // Only once, construct the rectification maps:
     if (!rectify_map.isSet())
       rectify_map.setFromCamParams(*obs_stereo);
     // Rectify in place:
     unmap.rectify(*obs_stereo);
     // Rectified images are now in: obs_stereo->imageLeft &
obs_stereo->imageRight
   }

Note: This class provides a uniform wrap over different OpenCV versions. The "alpha" parameter is ignored if built against OpenCV 2.0.X

Rectify the input image pair and save the result in a different output images - setFromCamParams() must have been set prior to calling this.

The previous contents of the output images are completely ignored, but if they are already of the correct size and type, allocation time will be saved. Recall that getRectifiedImageParams() provides you the new intrinsic parameters of these images.

Exceptions

std::exception If the rectification maps have not been computed.

Note: The same image CANNOT be at the same time input and output, in which case an exception will be raised (but see the overloaded version for in-place rectification)

void CStereoRectifyMap::rectify	(	mrpt::obs::CObservationStereoImages &	stereo_image_observation,

Overloaded version for in-place rectification of image pairs stored in a mrpt::obs::CObservationStereoImages.

Upon return, the new camera intrinsic parameters will be already stored in the observation object. If use_internal_mem_cache is set to true (recommended), will reuse over and over again the same auxiliary images (kept internally to this object) needed for in-place rectification. The only reason not to enable this cache is when multiple threads can invoke this method simultaneously.

Note: This method uses the left & right camera rotations computed by the rectification map to update mrpt::obs::CObservationStereoImages::cameraPose (left camera wrt the robot frame) and mrpt::obs::CObservationStereoImages::rightCameraPose (right wrt left camera).

Upon return, the new camera intrinsic parameters will be already stored in the observation object.

◆ setAlpha()

void CStereoRectifyMap::setAlpha ( double alpha )

Sets the alpha parameter which controls the zoom in/out of the rectified images, such that:

alpha=0 => rectified images are zoom in so that only valid pixels are visible
alpha=1 => rectified images will contain large "black areas" but no pixel from the original image will be lost. Intermediary values leads to intermediary results. Its default value (-1) means auto guess by the OpenCV's algorithm.

Call this method before building the rectification maps, otherwise they'll be marked as invalid.

Prepares the mapping from the distortion parameters of a camera.

Must be called before invoking rectify(). The alpha parameter can be changed with setAlpha() before invoking this method; otherwise, the current rectification maps will be marked as invalid and should be prepared again.
