Abstract

The invention discloses a three-dimensional model reconstruction method and device, equipment and a storage medium, and relates to the field of three-dimensional modeling. The method comprises the steps of obtaining a single target image, wherein the target image comprises an image of a target reconstruction object; performing feature extraction on the target image to obtain a target feature map corresponding to the target image; inputting the target feature map into a grid reconstruction network; the target feature map is input into a voxel reconstruction network, the grid reconstruction network and the voxel reconstruction network are in semantic connection, the grid reconstruction network is used for reconstructing a three-dimensional grid model of a target reconstruction object according to the target feature map, and the voxel reconstruction network is used for reconstructing a voxel model of the target reconstruction object according to the target feature map; and constructing atarget three-dimensional model according to the target grid information output by the grid reconstruction network. In the embodiment of the invention, the three-dimensional model reconstruction of thetarget reconstruction object can be realized by only needing a single image, the requirement on a two-dimensional image required by three-dimensional reconstruction is reduced, and the three-dimensional reconstruction process is simplified.

Description

technical field [0001] The embodiments of the present application relate to the field of 3D modeling, and in particular to a method, device, device and storage medium for reconstructing a 3D model. Background technique [0002] 3D reconstruction is a technique for constructing 3D models based on 2D images. [0003] In related technologies, when performing three-dimensional reconstruction based on two-dimensional images, it is first necessary to acquire multiple two-dimensional images, and the multiple two-dimensional images are obtained by shooting the same reconstructed object from different angles. By encoding multiple two-dimensional images (that is, the feature extraction process), and then decoding the encoded results (that is, the process of reconstructing three-dimensional voxels based on image features), a three-dimensional voxel model corresponding to the reconstructed object is constructed. [0004] However, when performing 3D reconstruction through the above meth...

Problems solved by technology

[0004] However, when performing 3D reconstruction through the above method, it is necessary to take multiple 2D images for 3D reconstruction first. The process of 3D reconstruction is complicated, and only reconstructed objects with entities can be reconstructed, resulting in 3D reconstruction. Application scenarios are limited
