Direct calibration is a simple but reliable method for measuring range profiles of 3D

- Build a look-up-table that relates images coordinates (xim, yim) where a scene point is
seen when illuminated by a laser line with its 3D coordinades (X, 0, Z). Y=0 is the laser
- To scan an object, move it along the Y axis while capturing images, recording the
displacement Y - Y0 and looking up for X and Z.
