1. A method comprising:
performing upsampling on a first feature of a first point cloud of a target object;
determining a reference feature of a second point cloud of a reference object;
determining a second feature based on the first feature subjected to upsampling and the reference feature; and
generating a third point cloud of the target object based on the second feature and the second point cloud of the reference object, wherein the third point cloud has a larger number of points than the first point cloud;
wherein determining the second feature comprises:
performing multiple instances of feature extraction on the reference feature to obtain a dense feature;
performing location coding on the second point cloud to generate location codes;
determining a first parameter and a second parameter based on the dense feature and the location codes; and
determining the second feature based on the first parameter, the second parameter, and the first feature subjected to upsampling.
