中文摘要: 针对目前条码识别算法实时性不够的不足,同时为解决具体应用中定位算法稳定性不高,景深不够等问题,提出了一种基于计算机视觉、FPGA和DSP混合设计的条码识别系统,其高速条码定位算法在FPGA上实现,定位时间仅为2.5ms,定位速度快,同时减少了后续DSP的计算量,大大提高了系统的实时性,并应用于轮胎条码识别系统.经实际试验表明,该系统达到16帧每秒的识别速度,且识别率高,对高速运动条码信息的在线检测应用具有较好的实用价值.
Abstract:In order to solve the lack of timeliness in barcode recognition's algorithms, the inadequate stability in the application of locating, the insufficient depth of field and etc., it introduce a mixed designed barcode recognition system based on computational vision, FPGA and DSP, the high-speed locating could be achieved with the locating time of only 2.5 ms, reduces the amount of DSP's computation, greatly enhances the timeliness of system and be applied to the tire barcode Recognition system. Experiments results show the system can recognize 16 frames per second with a high recognition rate, which is of practical value in online detection of rapidly moving barcodes.
