Depth map 1 |
Depth map 2 |
Depth map 3 |
Depth map 4 |
NOTE: The red regions in the depth maps indicate areas of uncertainty.
This is detected by the left-right consistency check in the algorithm. Decreasing
the amount of left-right consistency tolerance gives accurate but sparser depth maps,
especially for uncalibrated stereo pairs. In the above example, the tolerance factor
is set to some reasonable value.
