An integrated system for automated 3D visualization and monitoring of vehicles

Abstract

Recent technological advances in computer vision and the advent of commercial RGB-D sensors have certainly boosted 3D modeling applications. This work presents an integrated system that enables the digitization of big objects, like vehicles, with low-cost RGB-D sensors. The implemented system can be used for visualization and monitoring of vehicles in large fleets that currently require a time-consuming manual inspection process. The main objective is to achieve an efficient consolidation of multiple views of a vehicle inside a moving frame, to acquire color and depth data and generate its 3D representation. The proposed integrated system denoises the acquired depth maps, aligns the produced point clouds captured in different time instances, and builds the 3D-reconstructed mesh. Finally, we apply a texture mapping algorithm to acquire realistic texture details and remove any visible seams. We evaluate all modules of the implemented system by performing several experiments with scanned vehicles.
