Ground truth reprojection
=========================

**Name**: "ground_truth_reprojection"

**Description**

Generates epipolar and sensor ground truth from input dsm using direct localization.

* Sensor ground truth contains altitude in sensor geometry.
* Epipolar ground truth contains disparity map in epipolar geometry.
