针对客车超载设计了一种超载限速系统。一方面通过车载摄像头采集路面限速标志,进行小波去噪处理后,与图片库中图片进行匹配,确定出限速值;另一方面,利用车载光电传感器对车载乘员进行计数,根据乘员数的多少以及路面限速值来确定油门踏板限位器的伸缩量,进而对超载车辆的行驶速度进行限制。 Aiming at the overload of bus, an overload speed limit system is designed. On the one hand through the vehicle camera collection of road speed limit signs, after the wavelet denoising processing, and pictures in the picture to match, to determine the speed limit; On the other hand, the use of automotive photoelectric sensors for vehicle occupants, according to the number of passengers How much and pavement speed limit to determine the amount of expansion and contraction of the accelerator pedal, and thus overloaded vehicles to limit the speed of travel.
