【摘要】 为实现货车车厢号码的计算机自动识别，首先针对原车厢号码所包含的信息，设计了一种新型标记牌，随后以此标记牌为识别对象，设计了由线阵ＣＣＤ和计算机构成的货车车厢号码自动识别系统．原理性实验表明，该系统对以大约２ｍ／ｓ通过视场的标记牌，当黑白对比度降低不大于２０％时，识别准确率均能达到１００％．更多还原

【Abstract】 In order to recognizing the carrige number of locomobile automatically,a new type of indication aimming directly at the information of original carrige number of the locomobile was designed firstly,then,the new indication was taken as a target to be recognized,and an automatic recognition system for the carrige number of the locomobile was designed,which was composed of a line scan CCD and computer systemThe principle experiment showed: when the indication which including information more than 80% passed by the field of vision of the system at speed of 2m/s,the recognition accuracy could achieve 100%.更多还原
