THREE-DIMENSIONAL HUMAN BODY MODEL RECONSTRUCTION METHOD, STORAGE DEVICE AND CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/077295
Kind Code:
A1
Abstract:
A three-dimensional human body model reconstruction method, a storage device and a control device, wherein same are aimed at solving the problem of misalignment between a three-dimensional model reconstruction result and a two-dimensional image, etc. The reconstruction method comprises: according to a human body image, acquiring a global UVI image and a local UVI image of a human body part using a full convolutional network module (S1); on the basis of the global UVI image, estimating camera parameters and shape parameters of a human body model using a first neural network (S2); on the basis of the local UVI image, extracting rotation features of joint points of a human body using a second neural network (S3); on the basis of the rotation features of the joint points of the human body, improving the rotation features using a feature improvement strategy based on location aiding, in order to obtain improved rotation features (S4); and according to the improved rotation features, estimating pose parameters of the human body model using a third neural network (S5). According to the method, human body model reconstruction can be performed more accurately and efficiently, and the robustness of pose estimation is improved.
