Abstract

Un système de traitement dimages permettant dinspecter une distance à un objet et ses dimensions est décrit. Une caméra portative étalonnée dotée dun laser collimaté intégré est déployée afin de capturer des images dentrée. Les images sont ensuite traitées afin de déterminer la distance à lobjet et des paramètres associés tels que des déplacements et des dimensions de surface.
