Vehicle navigation system using point cloud based pose estimation

摘要

Embodiments of the disclosure provide systems and methods for positioning a vehicle. The system includes a communication interface configured to receive point cloud frames with respect to a scene and initial pose data of a vehicle captured by sensors equipped on the vehicle as the vehicle moves along a trajectory. The system also includes a storage configured to store the point cloud frames and the initial pose data. The system further includes a processor configured to estimate pose information of the vehicle associated with each of the point cloud frames based on the initial pose data and the point cloud frames. The processor is also configured to adjust the estimated pose information of the vehicle based on a model. The model includes a spatial relationship and a temporal relationship among the plurality of point cloud frames. The processor is further configured to position the vehicle based on the adjusted pose information.
