The invention relates to a vehicle positioning method and device, a vehicle, a storage medium and a chip, and the method comprises the steps: collecting a plurality of frames of driving environment images in a vehicle driving process through a vehicle-mounted camera, and enabling the driving environment images to comprise an image of a same road signboard; obtaining vehicle pose information corresponding to each frame of the driving environment image; constructing a target ellipsoid corresponding to the road signboard according to the multiple frames of driving environment images and the vehicle pose information corresponding to each frame of driving environment image; and performing position matching on the target ellipsoid and a target road signboard in a high-precision map to determine a target position of the vehicle. Therefore, high-precision positioning of the vehicle can be realized according to the target ellipsoid corresponding to the road signboard, and the high-precision positioning efficiency of the vehicle can be effectively improved while the accuracy of a high-precision positioning result is effectively ensured.

    本公开涉及一种车辆定位方法、装置、车辆、存储介质及芯片,该方法通过车载相机采集车辆行驶过程中的多帧行驶环境图像,所述行驶环境图像中包括同一个道路标识牌的图像;获取每帧所述行驶环境图像对应的车辆位姿信息;根据所述多帧行驶环境图像和每帧所述行驶环境图像对应的所述车辆位姿信息构建所述道路标识牌对应的目标椭球体;将所述目标椭球体与高精地图中的目标道路标识牌进行位置匹配,以确定所述车辆的目标位置。这样,能够根据该道路标识牌对应的目标椭球体实现车辆的高精度定位,能够在有效保证高精度定位结果准确性的同时,有效提升车辆的高精度定位效率。
