Title
(EN) REFLECTIVE CABLE LOCATING SYSTEM
(FR) SYSTÈME DE LOCALISATION DE CÂBLE RÉFLÉCHISSANT
Abstract
(EN)
A reflective cable system for a geophysical survey system includes a reflective cable that includes a conductive wire surrounded by an electrically insulating sheath and an exterior surface. The reflective cable includes reflective material that is on or visible through the exterior surface and that is configured to reflect a complete spectrum of light provided by a light source back to the light source. The reflective cable system also includes a connector electrically coupled to at least one end of the reflective cable and configured to couple to a geophysical survey system. The reflective cable may be used to locate the reflective cable in a physical environment and used to determine a position of the reflective cable using lidar or photogrammetry for generating geophysical survey models.

La présente invention concerne un système de câble réfléchissant pour un système de prospection géophysique comprenant un câble réfléchissant qui contient un fil conducteur entouré par une gaine électriquement isolante et une surface extérieure. Le câble réfléchissant comprend un matériau réfléchissant qui se trouve sur la surface extérieure ou est visible à travers celle-ci et qui est conçu pour réfléchir un spectre complet de lumière fourni par une source lumineuse et la renvoyer vers la source lumineuse. Le système de câble réfléchissant comprend également un connecteur couplé électriquement à au moins une extrémité du câble réfléchissant et conçu pour se coupler à un système de prospection géophysique. Le câble réfléchissant peut être utilisé pour localiser le câble réfléchissant dans un environnement physique et pour déterminer une position du câble réfléchissant à l'aide d'un lidar ou d'une photogrammétrie afin de générer des modèles de prospection géophysique.
