specific Embodiment approach

[0055] figure 1 A general flow diagram of the invention is shown. From figure 1 It can be seen that the input video data needs to go through several steps such as feature matching, key frame selection, 3D point cloud generation, template mapping, texture mapping, etc., to obtain the final complete human body model. Its specific implementation is as follows:

[0056] (1) Human body video data preparation.

[0057] Subject A wears tights printed with rich texture patterns (specifically, black and white checkerboard grids) and keeps standing still. The testee's arms should not hang down naturally or close to the body, but should be kept straight and slightly open to the sides of the body by 25 to 50 degrees; similarly, the testee's legs should not be close together, and should keep an upright posture and shoulder-width apart. Measurer B uses a mobile phone or a digital camera to shoot a video around subject A.

Abstract

The invention discloses a real human body three-dimensional modeling method specific to personalized virtual fitting. According to the method, a video is used as input data; and several steps of feature matching, key frame selection, three-dimensional point cloud generation, template mapping, and texture mapping and the like are carried out to obtain a human body surface three-dimensional model. Because of the motion recovery structure technology, the reconstruction process is substantially simplified, the burdens of the data collection people and the collected people can be reduced, and the requirements on the instrument and equipment are reduced. Meanwhile, a precise reconstruction result can be obtained. A complete human body surface model is obtained based on template mapping; and thus the method has high robustness on the human body texture information missing and self-shielding. Therefore, only a plurality of control points need to be marked manually before template mapping from the data input to model output and other process is completed automatically. The model that is obtained based on reconstruction can be applied to the game and animation design, movie and television special efficacy, and personalized virtual fit and the like.

Description

technical field [0001] The invention belongs to the field of computer vision, and in particular relates to a real human three-dimensional modeling method for personalized virtual fitting. Background technique [0002] With the development of virtual reality technology, three-dimensional modeling of the human body has received more and more attention, and has become the basic link of technologies such as film and television special effects, animation simulation, and virtual fitting. Existing human body 3D surface reconstruction methods mainly include active measurement methods, parametric modeling methods and modeling methods based on depth images. [0003] The active measurement method refers to the use of laser scanners, structured light scanners and other equipment to scan the surface of the human body and obtain the three-dimensional coordinates of the point cloud. Using this type of equipment to obtain 3D information on the target surface is relatively straightforward, ...
