A real-time calculation method of digital human cloth based on deep learning

Abstract

The present invention provides a real-time calculation method for digital human cloth based on deep learning, which includes the following steps: S1: training neural network, training autoencoder and fully connected network to map skeleton information to the coding of cloth grid vertices; S2: in After training the above two neural networks, given a set of input skeleton information, first pass through the fully connected network to obtain the code of the vertices of the cloth mesh, and then pass through the decoding link in the autoencoder to obtain the vertices of the output cloth mesh, the output It is the calculation result of the cloth. The present invention calculates the grid vertex information of the cloth in real time, effectively avoids the problem of character models interspersed with the cloth model, and further improves the cloth production efficiency.

Description

technical field [0001] The invention belongs to the technical field of animation production, and in particular relates to a real-time calculation method for digital human cloth based on deep learning. Background technique [0002] In the current film and television animation production process, the animation data of clothing cloth is calculated by establishing a mathematical physical model to simulate the movement of the cloth in a real scene to calculate the final effect, that is, the three-dimensional coordinate value of the vertices of the cloth mesh in each frame. Modeling and simulation means that calculating the three-dimensional coordinates of the vertices of each frame consumes a lot of resources. Therefore, the current digital human cloth generally adopts the offline calculation method, that is, the cloth of each frame is calculated in advance according to the skeleton animation of the character. Grid vertex information, written into the cache, and called out when n...

AI Technical Summary

Problems solved by technology

[0003] Due to the nature of the calculation process of modeling simulation, the specific size and shape of the cloth must be changed according to the change of the character model, otherwise it will lead to the phenomenon that the cloth and the character model are interspersed, and manual refinement is required

[0004] After the cloth animation is solved, if the character skeleton animation is modified in the later stage, the corresponding cloth animation needs to be recalculated to generate a new cache, and the cloth production efficiency is low.
