Real-time hardware/software co-design of a traffic sign recognition system using Zynq FPGA

This paper describes a hardware implementation for real-time road signs recognition system on automotive oriented FPGA. The proposed traffic sign recognition system is based on color segmentation and Template Matching. This architecture is implemented on FPGA device of ZYNQ 7020 Xilinx family. Therefore, a software/hardware co-design architecture for a Zynq-7020 FPGA is presented as a primary objective of this work. Results show that the proposed system achieves over 97% accuracy even in difficult condition weather. In addition, in this work, a hardware implementation of the proposed system will be presented to achieve real-time constraints.
