Title:
METHOD AND APPARATUS FOR COMPLETING SHAPE OF THREE-DIMENSIONAL OBJECT, AND DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/184759
Kind Code:
A1
Abstract:
Disclosed in the present application are a method and apparatus for completing the shape of a three-dimensional object, and a device and a storage medium. In the present solution, the method comprises: acquiring a three-dimensional point cloud of a three-dimensional object; inputting the three-dimensional point cloud into a point cloud encoder, extracting, by means of the point cloud encoder, point cloud local features and point cloud non-local features from three-dimensional point clouds at different resolutions, and fusing the point cloud local features and the point cloud non-local features at different resolutions, so as to obtain point cloud multi-scale features; and inputting the point cloud multi-scale features into a point cloud decoder, obtaining, by means of the point cloud decoder, initial features of a complete shape of an object that correspond to the point cloud multi-scale features, performing hierarchical decoding on the initial features, and performing prediction to obtain a complete shape of the three-dimensional object that corresponds to the three-dimensional object.
