摘　　要：利用减影法和Hough变换对指针式汽车仪表指针的识别进行研究。PCI-6024E数据采集卡发出标准信号驱动汽车仪表,由CCD摄像机获取汽车仪表图像传输至计算机,应用中值滤波、二值化和细化对仪表图像进行预处理。然后根据减影法、Hough变换提取目标信息,确定仪表读数。实验结果表明,该方法简便、精度高。RSM-DSA method and Hough transformation are used for dials identification of motor meters.PCI-6024E output drives motor meters,and then the images of motor meters are transformed from CCD to computer.The data are pre-processed with media filter,image binaryzation and thinning,and then object formation is extracted with RSM-DSA and Hough transformation to confirm the records of the meter.Experiment results show the method is reliable and simple with high precision.
