3D scene reconstruction for design information verification
The objective of Design Information Verification (DIV) is to determine the difference between the design plans of a facility and the facility itself as-built, as well as to maintain continuity of knowledge using re-verification. Different strategies can be envisaged for determining the difference between design plans and the reality. For all strategies there is the need to acquire data from the real plant. The approach that is followed uses a laser range finder for the acquisition of 3D data from the real scene, providing volumetric information regarding the scene to be modelled. The paper describes the different steps leading to the 3D scene reconstruction: 3D data acquisition, geometrical feature extraction, registration and integration of 3D data from multiple views to compensate for occlusions, and scene modelling. The reconstructed scene will ultimately be compared with the original blueprints of the plant. Preliminary results regarding dynamic range sensing are also presented.
