Detection, recognition, and positioning of road signs are critical components of a roadway asset management system. In this research, a stereo vision-based system is developed to conduct automated road sign inventory. The system in real time integrates and synchronizes the data streams from multiple sensors of high-resolution cameras, Differential Global(More)
