Tóm tắt

Detection and recognition of traffic sign while driving is not a trivial task because the external environment is surfeited of road signs, billboards, adverts, shop fronts, etc… Currently, an automatic traffic sign detection and recognition system is under research because this system provides an additional level of driver assistance, leading to improved safety for passengers, road users and vehicles. In this paper, the algorithm of Speed Limit Traffic Sign Detection and Recognition will be researched.
The system works in two layers: detection and recognition. Sign detection stage finds speed limit sign by using color segmentation combined with shape detection and pixel connectivity; and speed limit sign recognition classifies the speed information inside the sign by using scan-line technique.
The proposed method was tested on Vietnamese traffic signs with successful detection and recognition rate of about 99% in case of static images and about 84.6% in case of the input being video streams.
