Abstract

L'invention concerne une unité d'exploration (24) comprenant un compas en 3D (61) et une caméra vidéo (58) montée sur l'unité, lors de son utilisation, destinée à capturer des images vidéo d'une face du compas. Des dispositifs de communication de données (56, 20, 68, 74) connectés à la caméra servent à transmettre les données concernant les images à un ordinateur à distance (78) qui traite les données afin d'afficher les images en temps réel sur un écran (82). Les données obtenues à partir des images affichées à différentes profondeurs dans le trou et les données concernant les profondeurs correspondantes sont utilisées pour calculer et pour représenter graphiquement un profil du trou.
