Embodiment 1

[0027] This application provides a method for constructing a virtual avatar. figure 1 It is a flow chart of the construction method of the virtual avatar provided by this application.

[0028] like figure 1 As shown, the construction method of the virtual avatar comprises the following steps:

[0029] S110: Acquire a multi-angle clothing image, where the multi-angle clothing image records features of the object being photographed at 360° angles.

[0030] The multi-angle clothing shooting image is an image obtained by using a camera to shoot from multiple angles on the basis that the object to be photographed (such as the measured human body or avatar) is wearing tight clothing.

[0031] As an embodiment, the feet of the subject abut against the turntable, and the subject and the turntable have a fixed positional relationship, the bottom of the turntable is connected to the base, and the turntable is rotatably connected to the base. During the shooting process, the position ...

Embodiment 2

[0124] The present application also provides a system for constructing a virtual avatar, which includes a processor, and the processor is the above-mentioned method for constructing a virtual avatar.

[0125] The beneficial effect that this application obtains is as follows:

[0126] 1. This application utilizes all the points in the clothing shooting images to construct a fused mannequin to form a virtual avatar, which greatly reduces the error between the size of the mannequin and the actual size of the object being photographed.

[0127] 2. This application utilizes images obtained from multiple shooting angles formed by multiple rotations within the 360° range of clothing shooting images to construct stitched images under a predetermined viewing angle, so that the stitched images fully reflect the characteristics of all parts of the subject to be photographed, so the human body The model can better reflect the characteristics of the subject being photographed.

Abstract

The invention discloses a virtual mannequin construction method and system. The method comprises the steps: acquiring multi-angle garment shot images; obtaining a first three-dimensional feature map of each garment shot image under a plurality of preset visual angles; and fusing the first three-dimensional feature maps of the multi-angle clothing shot images under a plurality of preset visual angles to form a fused human body model as a virtual mannequin. According to the invention, all points in the garment shot image are utilized to construct the fused human body model to form the virtual mannequin, so the error between the size of the human body model and the actual size of the shot object is greatly reduced.

Description

technical field [0001] The present application relates to the technical field of non-contact anthropometry, and in particular to a method and system for constructing a virtual mannequin. Background technique [0002] In recent years, there have been many applications of computer vision graphics in the construction of non-contact 3D human models. In the prior art, multiple two-dimensional images of the human body at different angles are obtained through an image generator, and the image processor calculates the zoom ratio of the two-dimensional image according to the positional relationship of the human body feature points in each two-dimensional image, and then according to each two-dimensional The zoom ratio of the image and the identified human body feature points generate three-dimensional human body feature points, and finally calculate the required human body shape data through the three-dimensional human body feature points, and then construct the human body model. ...
