License Plate Recognition System Based on the Hardware Acceleration Technology on the ZYNQ

摘要

For the disadvantage of high cost and poor practicability of traditional license plate recognition technology based on PC, apply this technology on the ZYNQ to implement the hardware acceleration of the license plate recognition algorithm. The platform consists of programmable logic (PL) and a processing system (PS). The hardware acceleration of the algorithm of license plate location is completed through the part PL; On the PS runs the Linux system. In terms of license plate recognition algorithm, we use the edge detection algorithm, vertical projection method and template matching method respectively for the location of license plate image, character segmentation and recognition. Finally, it implement the Hardware acceleration of license plate recognition and reduce the time for the license plate recognition algorithm.
