The invention provides a virtual track detection system and a method thereof, and belongs to the field of vehicle detection, a track pattern is drawn on a track, and a plurality of positioning elements are laid along a curve of the track. When the vehicle runs on the track, the image acquisition device acquires images of a road ahead, and the processor identifies the track pattern from the images and judges whether the running path of the vehicle is a straight line or a non-straight line according to the track pattern. If the driving path is a straight line, calculating a linear equation of the driving path and outputting the linear equation to a power control end of the vehicle-mounted system; if the driving path is non-linear, the position of the positioning element is detected through an inductor, and a curve curvature, a turning speed of the vehicle and a correction angle are calculated according to the position of the positioning element, so that the power control end corrects the driving speed and the course angle of the vehicle. According to the invention, images are combined with magnetic conductance type virtual track detection, so that the method is not influenced by external environment, and the cost can be reduced.
本发明提供一种虚拟轨道检测系统及其方法,属于车辆检测领域,轨道上画设有一轨道图案,且沿着轨道的弯道铺设有复数定位元件。当车辆在轨道上行驶,通过影像采集装置采集前方道路影像,处理器从中辨识出轨道图案,并据以判断车辆的行驶路径为直线或非直线。若行驶路径为直线,计算行驶路径的线性方程式并输出至车载系统的一动力控制端。若行驶路径为非直线,则通过一感应器检测定位元件的位置,根据定位元件的位置计算一弯道曲率、车辆的一过弯速度及一修正角度,以供动力控制端修正车辆的行驶速度及航向角度。本发明将影像与磁导式虚拟轨道检测相结合,不受外在环境影响,可减少成本。
