Abstract

The invention discloses a human body 3D modeling method based on mobile phone scanning. The method is applied to a mobile phone. The method includes the following steps: S1: generating a TSDF 3D meshmodel; S2: performing intensive image calibration; S3: performing key frame selection; S4: performing intensive image matching to generate a depth image; S5: performing volumetric mesh model updating;and S6: generating a human body 2D image on a mobile phone screen. The method uses the camera of the mobile phone to carry out three-dimensional modeling of the human body, does not require any accompanying equipment, and uses the mobile phone's own computing power to complete the three-dimensional modeling and calculation of the human body. By using the principle of human symmetry, as long as the half body is scanned, the system will perform 3D automatic generation of the entire human body; the user's scanning time is greatly saved, and when the user holds a mobile phone in one hand, 3D modeling cannot be influenced if scanning is inconvenient; and any data about the consumer is not required, the operation is simple, and the cost is low.

Description

technical field [0001] The invention belongs to the field of 3D modeling, and in particular relates to a human body 3D modeling method based on mobile phone scanning. Background technique [0002] Building a three-dimensional (3D) model of the human body in the field of clothing is the basis for three-dimensional virtual fitting, three-dimensional virtual reality (VR) and other applications. [0003] At present, the following methods are mainly used in China to realize. [0004] The first: three-dimensional (3D) software modeling. [0005] The second type: three-dimensional (3D) scanning modeling. [0006] The third: model replacement method. [0007] The first one uses three-dimensional (3D) software to establish a three-dimensional model of the human body, which requires the use of 3D software tools to modify the model. It is difficult to automatically obtain a three-dimensional model consistent with the body shape of an individual subject in a short period of time. B...
