Abstract

The embodiment of the invention discloses a method, device and equipment for carrying out three-dimensional reconstruction on a two-dimensional image and a storage medium, and belongs to the technicalfield of image processing. The method comprises steps of obtaining a two-dimensional picture set; performing feature point extraction on a single picture in the two-dimensional picture set to obtaina feature point set; obtaining the size of the picture and the position information of the feature points in the feature point set in the corresponding picture; acquiring position information of the feature points in a world coordinate system based on an OpenCV camera calibration method; based on an LSD straight line detection method and the position information of the feature points in the worldcoordinate system, obtaining a horizontal line segment in the picture; constructing a three-dimensional grid chart corresponding to the picture based on a constraint Delaunay algorithm; and combiningthe three-dimensional grid diagrams constructed by the pictures in the two-dimensional picture set to obtain a three-dimensional surface model of the object, thereby completing three-dimensional reconstruction. According to the invention, three-dimensional simulation reconstruction can be carried out on the two-dimensional picture rapidly and accurately; and the manpower and material resource consumption during three-dimensional reconstruction can be reduced.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a method, device, device and storage medium for three-dimensional reconstruction of two-dimensional images. Background technique [0002] Three-dimensional reconstruction refers to the establishment of mathematical models suitable for computer representation and processing of three-dimensional objects. 3D reconstruction of objects is a common scientific problem and core technology in the fields of computer-aided geometric design (CAGD), computer graphics (CG), computer animation, computer vision, medical image processing, scientific computing and virtual reality, and digital media creation. There are two main methods for generating 3D representations of objects in a computer. One is to use geometric modeling software to generate 3D geometric models of objects under human control through human-computer interaction, and the other is to obtain the geometric s...
