Publication number: 20250104344Abstract: There are provided an apparatus and a method for reconstructing a 3D human object in real time based on a monocular color image. A 3D human object reconstruction apparatus according to an embodiment extracts a pixel-aligned feature from a monocular image, extracts a ray-invariant feature from the pixel-aligned feature, generates encoded position information by encoding position information of a point, predicts a SD of a point from the ray-invariant feature and the encoded position information which are extracted, and reconstructs a 3D human object by using the predicted SD. Accordingly, the ray-invariant feature extracted from the pixel-aligned feature, and the encoded position information are used, so that an amount of computation for predicting SDs of points of a 3D space can be noticeably reduced and a speed can be remarkably enhanced.Type: ApplicationFiled: December 13, 2022Publication date: March 27, 2025Applicant: Korea Electronics Technology InstituteInventors: Min Gyu PARK, Ju Hong YOON, Ju Mi KANG, Je Woo KIM, Yong Hoon KWON
