Publication number: 20240054661Abstract: A method for determining a trajectory of a vehicle within a physical space based at least on an aligned point cloud may include generating a fused feature map by concatenating a first feature map corresponding to a source point cloud and a second feature map corresponding to a target point cloud. A machine learning model may be applied to determine, based at least on the fused feature map, a relative transform aligning the target point cloud to the source point cloud. An aligned target point cloud may be generated by transforming the target point cloud in accordance with the relative transform. Furthermore, a trajectory of a vehicle within the physical space may be determined based on at least the first relative transform. Related systems and computer program products are also provided.Type: ApplicationFiled: March 31, 2023Publication date: February 15, 2024Inventors: Sherif Ahmed Morsy NEKKAH, Nicole Alexandra CAMOUS, Sergi Adipraja WIDJAJA, Venice Erin Baylon LIONG, Xiaogang WANG
