Miguel Ángel García, Miguel Ángel Sotelo, Ernesto Martín-Gorostiza · 2004
Abstract: A system for real-time traffic sign detection is described in this paper. The vision-based traffic sign detection module developed in this work is intended for assisted driving of road vehicles by handling color images in RGB (Red, Green and Blue) format. In a first step a preattentive area of interest is determined based on the vertical projection of edge pixels. In a second step, a shape analysis is performed. In a third step, a color analysis is performed, and finally, a template is fitted. Some results obtained on a series of real road images are presented in order to illustrate the robustness of the detection system. 1
