The invention relates to the technical field of computers, in particular to a vehicle positioning method and device, a vehicle and a storage medium, and the method comprises the following steps: obtaining a current position of the vehicle and an image of a current road section; processing the image to obtain a lane line model, and calculating a first distance between the vehicle and the target side boundary of the current road section by using the lane line model; acquiring a map of the current road section by using the current position, projecting the current position onto the map, and calculating a second distance from the vehicle to the target side boundary of the current road section according to the map and the projection point; and matching a positioning error value according to the distance difference between the first distance and the second distance, and correcting the current position of the vehicle by using the positioning error value. Therefore, the problems of high vehicle cost and the like when a high-precision inertial navigation system is used for improving the positioning precision in related technologies are solved.
本申请涉及计算机技术领域,特别涉及一种车辆定位方法、装置、车辆及存储介质,其中,方法包括以下步骤:获取车辆的当前位置和当前所处路段的图像;对图像进行处理得到车道线模型,利用车道线模型计算车辆距离当前所处路段目标侧边界的第一距离;利用当前位置获取当前所处路段的地图,将当前位置投影至地图上,根据地图和投影点计算车辆距离当前所处路段目标侧边界的第二距离;根据第一距离与第二距离的距离差值匹配定位误差值,利用定位误差值修正车辆的当前位置。由此,解决了相关技术中使用高精度的惯导系统提高定位精度,车辆成本较高等问题。
