基于DM6446的车牌定位算法实现与优化

his paper introduces the hardware and software architecture of TI DM6446 dual core processor. The communication between ARM and DSP has been realized by Codec Engine of Davinci Technology, and then the license plate location algorithm has been implemented based on this embedded system. In this paper, the modification of the code and the interface of xDM standard are mainly discussed. Based on the features of DSP, The license plate location algorithm has been optimized from the aspect of C language. The results demonstrate that the algorithm can achieve the location of license plate quickly and accurately, which can meet the real-time requirements of the applications.
