Hybrid Approach For Traffic Sign Recognition
Reinhard Janssen, Walter Ritter, Fridtjof Stein, Simon Ott · 2005
In this paper we present a novel approach for the detec-tion and recognition of traffic signs. Colour images are acquired b y a camera mounted in a car. In the first step these images are colour segmented with a pixel classifier. Colour combinations which are characteristic for trafic signs generate hypotheses. These hypotheses are verified using a pictogram classifier. Our system has been successfilly tested on thousands of trafic scenes. The processing of a 512 b y 512 frame takes approximately 3 seconds on a Sparc-2. This project is part of the European research programme PROMETHEUS and is being developed b y Daimler-Benz in collaboration with various university labs. 1
