Accurate 3D Modelling by Fusion of Potentially Reliable Active Range and Passive Stereo Data

摘要

Possibilities of more accurate digital modelling of 3D scenes by fusing 3D range data from an active hand-held laser scene scanner developed in IRL and passive stereo data from stereo pairs of images of the scene collected during the scanning process are discussed. Complementary properties of two data sources allow for improving a 3D model by checking reliability of active range data and using it to adaptively guide passive stereo reconstruction. Experiments show that this avenue of the data fusion offers good prospects of error detection and correction.
