Abstract
The present disclosure provides a point autoencoder including an encoder receiving a 3D point cloud and extracting a global feature and a decoder reconstructing the 3D point cloud from the global feature; a dual autoencoder including the point autoencoder; and a method for dimensional transformation of a point cloud using the dual autoencoder. According to the present disclosure, it is possible to extract features from an input point cloud using a Bias-Induced Decoding (BID) layer, perform reconstruction of a 3D point cloud from the corresponding feature information, and reconstruct a 3D point cloud by using only high-dimensional global features as an input. Also, the present disclosure reduces the amount of storage space used and reduces computational complexity than the conventional structure employing a fully connected layer.
