Abstract

The invention provides a clothes processing method and device based on double three-dimensional distance fields. The method comprises the following steps: extracting a clothes three-dimensional point cloud under a standard posture from a preset human body clothes data set, and obtaining first normal information of each piece of clothes; according to the clothes three-dimensional point cloud and normal information, extracting a three-dimensional distance field point cloud sample in a three-dimensional space; removing a point cloud part with a preset distance from the edge in the clothes three-dimensional point cloud, and extracting a three-dimensional unsigned distance field point cloud sample from the removed point cloud; establishing a dual distance field sample according to the three-dimensional distance field point cloud sample and the three-dimensional unsigned distance field point cloud sample; constructing a generative network, and training the generative network based on the dual distance field samples; obtaining a depth feature vector of to-be-processed clothes, and obtaining a dual distance field corresponding to the depth feature vector of the to-be-processed clothes through the trained generative network; based on a moving cube algorithm, obtaining a three-dimensional model of the to-be-processed clothes in the standard posture from the double distance fields.

Description

technical field [0001] The present application relates to the technical field of computer vision, and in particular to a method, device, computer equipment and storage medium for processing clothes based on a dual three-dimensional distance field. Background technique [0002] In the field of computer vision and graphics in China, 3D reconstruction technology has rich application value in science and technology, education, industry, entertainment and other aspects. The results of 3D reconstruction can be applied to virtual scenes, buildings and human body generation, which will greatly promote the development of virtual reality and augmented reality. As for the geometric generation and dynamic simulation methods of 3D human body clothes, it is difficult to continuously express and generate the topology and shape of different clothes with traditional methods, so it is a hot topic in computer vision research. Existing methods edit the shape features of clothes with fixed clot...
