METHOD OF THREE-DIMENSIONAL OBJECT RECONSTRUCTION Russian patent published in 2023 - IPC G06T7/593 

FIELD: machine vision; computer graphics.

SUBSTANCE: invention relates to the field of machine vision and computer graphics for three-dimensional reconstruction of objects. The technical result is to provide a fast and more accurate three-dimensional reconstruction of the target object. The technical result of the proposed solution is achieved by the fact that it provides for the stages at which a number of images of an object is formed using a camera from different angles and camera positions, the characteristic features of an object are extracted from this number of images; forming a cloud of three-dimensional points placed in a three-dimensional model representing the object; selecting an area in one of the plurality of images, which contains a projection of a predetermined three-dimensional geometric structure, as a building block of the object; identifying images, each of which contains features in a subset of said features; determining the first and second set of three-dimensional points; a mathematical equation is determined that corresponds to a predetermined three-dimensional geometric structure, through the first set and the second set of three-dimensional points; and visualization of a three-dimensional model of the object.

EFFECT: fast and more accurate three-dimensional reconstruction of the target object.
