Most of the vehicle license plate location systems were sensible to background interference,and the location accuracy was limited. To alleviate these problems,an embedded system of vehicle license plate location was designed based on image decomposition algorithm and DM6437 DSP. The system could capture the image information of the vehicle license plate by means of CCD camera and video decoder chip TVP5146,process algorithm operation,and realize transmission tasks by DM6437. And it could improve the location algorithm by incorporating image decomposition. The experimental results confirmed that the image decomposition could effectively remove the useless information in the background and improve the locating accuracy. The system was small in volume,stable in performance,and was worthy of promotion and application.
