SYSTEM FOR SCANNING, MAPPING AND MEASURING CONDUITS

摘要

The present invention relates to a system for scanning, mapping and measuring conduits. The system includes a data collection subsystem having a carriage assembly sized to fit within a conduit for travel therethrough and equipment module supported on the carriage assembly. The equipment module includes a housing, a video capture system and a lighting assembly accommodated within the housing, and a laser beam emitting and diffusion assembly attached to the housing forwardly of the video capture system. The laser beam emitting and diffusion assembly is operable to emit a laser beam and diffuse the laser beam along a plane P substantially perpendicular to the laser beam so as to trace a visible light contour where the plane P intersects the inner surface of the conduit. The laser beam is a light of a first colour. The video capture system is operable to record images of the conduit and the visible light contour generated by the laser beam emitting and diffusion assembly. The lighting assembly includes at least one LED light capable of emitting light of a second colour. The light of the second colour is different than the light of the first colour. The light of the second colour is selected so as provide sufficient illumination within the conduit to reveal features of the conduit when the at least one LED light is activated, while not substantially lessening the contrast of the visible light contour against the dark background formed by the conduit thereby allowing the images of the visible light contour of a sufficient quality to be captured for further processing. The system is further provided with a data processing subsystem that is in data communication with the data collection subsystem. The data processing subsystem being operable to process the images of the conduit and the visible light contour and to generate therefrom digital views of the conduit.
