Dimensionner et localiser une cavité souterraine en couplant un scanner laser 3D avec le système UGPS3

Abstract : INERIS regularly performs inspections of abandoned mines in order to assess their stability. Geotechnicians face many difficulties to locate and evaluate the size of underground cavities. It is the reason why, for many years, INERIS has been equipped with innovative tools. UGPS3 system (Underground Global Positionning System 3rd generation) enables the geo-localization at real-time of an underground position with an under metric accuracy. 3D laser scanner can scan underground cavities in three dimensions with a millimetric accuracy. Scanning gives new visuals and geotechnical data (mapping, volume, fracturing etc.) until then difficult to obtain by visual observation. The UGPS3 system and the 3D laser scanner can be easily and quickly used together during the same intervention. This way, an accessible cavity can be exactly sized and located geographically in its globality.
