2. Stereovision
2.1 Measurement principle
Stereoscopic depth imaging comprises four steps:
geometric calibration of the stereoscopic system ;
image rectification ;
the matching of image elements corresponding to the same 3D point between the two views, which amounts to estimating parallax;
3D triangulation of the scene.
Here, we're looking at stereoscopy in the so-called rectified configuration, in which the two cameras are identical and positioned next to each other so that their image planes coincide. This configuration, shown in figure 6...
