The invention provides an electric bicycle retrograde running detection method and an electric bicycle, and the method comprises the steps: obtaining the current running state of the electric bicycle, judging whether the electric bicycle is in a running state or not according to the current running state, and controlling a vehicle-mounted camera to enter a side bicycle snapshot mode when the electric bicycle is in the running state; effective images are extracted from environment images captured by a vehicle-mounted camera, the number of first-type reference vehicles and the number of second-type reference vehicles are determined according to the effective images, the first-type reference vehicles are vehicles with the heads facing the electric bicycle, and the second-type reference vehicles are vehicles with the tails facing the electric bicycle; and determining a ratio between the number of the first type of reference vehicles and the number of the second type of reference vehicles, and when the ratio is greater than a preset threshold value, determining that the electric bicycle is in a retrograde running state. By determining the ratio of the first type of reference vehicle to the second type of reference vehicle in the effective image, whether the electric bicycle is in the retrograde running state or not can be accurately detected.

    本发明提供一种电单车逆行检测方法及电单车,通过获取电单车的当前运行状态,根据当前运行状态判断电单车是否处于行驶状态,在电单车处于行驶状态时,控制车载摄像头进入旁车抓拍模式,从车载摄像头抓拍得到的环境图像中提取出有效图像,并根据有效图像确定第一类型参考车辆的数量和第二类型参考车辆的数量,其中,第一类型参考车辆为车头朝向电单车的车辆,第二类型参考车辆为车尾朝向电单车的车辆,确定第一类型参考车辆的数量和第二类型参考车辆的数量之间的比值,在比值大于预设阈值时,判定电单车处于逆行状态。本申请通过确定有效图像中第一类型参考车辆和第二类型参考车辆的比值,能够准确检测出电单车是否处于逆行状态。
