1. A 3D human object reconstruction apparatus comprising:
a feature extraction unit configured to extract a pixel-aligned feature from a monocular image;
a pointer configured to indicate points on a 3D space one by one in sequence;
a feature encoder configured to extract a ray-invariant feature from the pixel-aligned feature;
a position encoder configured to generate encoded position information by encoding position information of a point indicated by the pointer;
a decoder configured to predict a signed distance (SD) of a point from the ray-invariant feature and the encoded position information which are extracted; and
a reconstruction unit configured to reconstruct a 3D human object by using the predicted SD.
