The invention relates to a new energy vehicle charging positioning method and a new energy vehicle. A pantograph is provided with a two-dimensional code feature identifier, and the method comprises the steps of: obtaining an image through a camera when a vehicle drives into a charging parking space, and identifying the two-dimensional code feature identifier, then, positioning the position of thetwo-dimensional code feature identifier in the current image, comparing with the position of the two-dimensional code feature identifier in the standard image, calculating the position offset betweenthe two-dimensional code feature identifier in the current image and the two-dimensional code feature identifier in the standard image, and calculating the current position offset of the vehicle in combination with the position parameter of the busbar, the camera parameter and the position parameter of the pantograph, and finally, controlling the vehicle, so that the position offset of the vehicleis zero, and alignment and positioning of the busbar and the pantograph are completed. Position offset of the vehicle can be visually provided for a driver, the busbar and the pantograph can be accurately aligned conveniently when the driver drives the vehicle, and the charging positioning efficiency of the new energy vehicle is improved.

    本发明涉及一种新能源车辆充电定位方法和新能源车辆。本发明受电弓上设有二维码特征标识,首先在车辆驶入充电车位时,通过摄像头获取图像,识别出二维码特征标识;然后在当前的图像中定位二维码特征标识的位置,然后与标准图像中的二维码特征标识的位置进行比较,计算出当前的图像中的二维码特征标识与标准图像中的二维码特征标识的位置偏移,之后结合汇流排的位置参数、摄像头参数、受电弓的位置参数,计算出车辆当前的位置偏移;最后控制车辆,使车辆的位置偏移为零,完成汇流排与受电弓的对准定位。本发明能为驾驶员直观地提供车辆的位置偏移,方便其驾驶车辆完成汇流排与受电弓的精确对准,提高了新能源车辆充电定位的效率。
