Abstract

The invention discloses a three-dimensional reconstruction method, a face three-dimensional reconstruction method and related devices thereof. The method comprises the following steps: acquiring an image comprising a target object; obtaining feature parameters of the target object based on the image; performing convolution calculation on the feature parameters by using a neural network to obtain three-dimensional reconstruction parameters of the target object, wherein the neural network is obtained by solidifying the association relationship between the feature parameters and the three-dimensional reconstruction parameters; and performing three-dimensional reconstruction on the target object based on the three-dimensional reconstruction parameters. Through the method, power consumption and memory consumption caused by an algorithm in a three-dimensional reconstruction technology are reduced.

Description

technical field [0001] The invention relates to the field of image processing applications, in particular to a three-dimensional reconstruction method, a three-dimensional reconstruction method of a human face and related devices. Background technique [0002] The deep learning 3D face reconstruction technology based on a single image is the basic technology applied to digital, facial expression drive, AI 3D animation, and avater. The above application scenarios are all based on 3D face reconstruction technology. 3D face reconstruction is divided into parametric reconstruction method and non-parametric reconstruction method, and parametric reconstruction method is one of the important methods of 3D face reconstruction. [0003] The field of deep learning has been applied to many fields. With the business expansion of deep learning, the coverage is wider, and the requirements for the utilization of edge computing resources on the mobile terminal are getting higher and higher...
