Illumination-separated single-view-angle human body clothing geometric detail reconstruction method and device

Abstract

The invention discloses an illumination-separated single-view-angle human body clothing geometric detail reconstruction method and device. The illumination-separated single-view-angle human body clothing geometric detail reconstruction method comprises the steps: carrying out preliminary physical simulation on a human body model and a garment model through employing an existing method for obtaining the posture of a person from an image; and then through an illumination separation method, extracting light and shadow information of illumination and the surface of clothing, so that surface details of the clothing are modeled, and detail information such as wrinkles of the clothing is dynamically simulated according to the motion posture of a human body. Human body model reconstruction is based on a single image human body template fitting method, and the clothing simulation mainly utilizes a physical particle simulation framework; and the clothing surface detail reconstruction is comparedwith a decomposed intrinsic illumination image and solved through the rendering result of illumination and surface normal. According to the illumination-separated single-view-angle human body clothing geometric detail reconstruction method, through a framework of clothing modeling and surface detail solving, details of clothing in an input image can be well reconstructed, the illumination-separated single-view-angle human body clothing geometric detail reconstruction method can be suitable for human body and clothing reconstruction of single RGB collection human body movement.
