Abstract

The invention provides a half-body image three-dimensional reconstruction method and device which is used for solving the problems of high complexity and long reconstruction time. The method comprises the steps of obtaining an image of a front face including a half-body image of a target person, then performing texture expansion by adopting a head semantic mask of the front face to enable at least two organs in the expanded texture to be located at preset positions, and then complementing the texture of the back face according to the expanded texture image including the front face. In addition, a three-dimensional grid model can be constructed according to the front face, a pre-configured ear model is adopted to replace ears in the three-dimensional grid model, then the texture of the ear area is obtained from the replaced three-dimensional grid model and is fused to the texture of the complemented back face, and then the three-dimensional grid model is obtained, so that a professional modeling device is not needed, and the complexity is lower. Due to the fact that the front face texture and the back texture of the human body have certain correlation, the back texture is supplemented according to the front face texture, the constructed three-dimensional model better fits a figure, and a better effect is achieved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of image processing, and in particular to a method and device for three-dimensional reconstruction of a bust. Background technique [0002] At present, the 3D bust reconstruction technology has a wide range of applications in the fields of 3D printing, entertainment, and remote augmented reality (augmented reality, AR) calls. Traditional 3D bust reconstruction techniques can use monocular or multi-eye systems. When using a monocular system, an infrared depth camera is usually used to scan a person in a circle, and the person to be scanned needs to remain still during the scanning process. Therefore, this method takes a long time to scan a person, and takes a long time to reconstruct and calculate, and the scanning effect may be unsatisfactory or fail. The multi-eye scanning system is an acquisition system based on multi-view. Although it has the ability of real-time reconstructi...
