摘　　要：设计并实现了一种基于DSP平台的PDF417条码快速解码终端。该终端能对摄像头采集的含有PDF417条码的图像进行复杂背景下条码区域提取、条码畸变校正等条码图像预处理,实现了复杂背景和不均匀光照条件下条码的全方位快速读取。A fast PDF417 decoding terminal is designed and implemented based on DSP platform. This terminal collects images of PDF417 bareode by camera and is able to extract barcode regions from complex background, correct barcode deformation and etc. The designed device, even under unbalancing illumination or complex background, can decode PDF417 in a high speed regardless of the orientation of the barcode.
