要旨:
We compare two approaches to the problem of estimating the depth
of a point in space from observing its image position in two
different cameras: 1.~The classical photogrammetric approach
explicitly models the two cameras and estimates their intrinsic
and extrinsic parameters using a tedious calibration procedure;
2.~A generic machine learning approach where the mapping from
image to spatial coordinates is directly approximated by a Gaussian Process regression. Our results show that the generic
learning approach, in addition to simplifying the procedure of
calibration, can lead to higher depth accuracies than classical
calibration although no specific domain knowledge is used.
