Abstract
Embodiments of the disclosure provide systems and methods for positioning a vehicle. The system includes a communication interface configured to receive a point cloud with respect to a scene captured by a sensor equipped on the vehicle. The system further includes a storage configured to store the point cloud and a high definition map. The system also includes a processor. The processor is configured to create a first 3-D representation of the point cloud and create a second 3-D representation of the high definition map with respect to the scene. The processor is further configured to determine pose information of the vehicle by comparing the first 3-D representation and the second 3-D representation. The processor determines a position of the vehicle based on the pose information.
