Machine vision-based measurement system for vehicle body inspection

Abstract

The main contribution of the paper is to propose a system for fast and easy measurement of car body parts to support their inspection. The proposed system is composed from a camera-projector (CP) subsystem and a multi-camera and active marker based tracking system (TS). During the reconstruction process "rotating" gray code pattern is projected onto the targeted surface which improves the robustness and accuracy of the measurement. Afterwards based on triangulation the 3D coordinates of surface points are estimated.
