Abstract

The embodiment of the invention provides an object three-dimensional abstract model building method and device, a storage medium and a processor, and belongs to the technical field of engineering. Themethod comprises the steps that when a lifting hook of the engineering machine is located at the highest point of an object, obtaining the height of the lifting hook so as to obtain the height of theobject; acquiring a horizontal plane projection of the object; obtaining a graph containing the horizontal plane projection; obtaining basic data of the graph, wherein the basic data can construct the graph; and establishing a three-dimensional abstract model of the object according to the height of the object and the basic data of the graph. The method is simple in modeling and short in modelingtime.

Description

technical field [0001] The invention relates to the technical field of engineering, in particular to a method, device, storage medium and processor for establishing a three-dimensional abstract model of an object. Background technique [0002] The existing scene modeling methods mainly include two modeling methods based on vision and lidar. Vision-based 3D scene modeling methods generally use binocular or multi-eye cameras to collect 3D scenes, obtain their projected 2D images, and restore depth information based on image texture distribution and other information to achieve 3D modeling. The 3D scene modeling method based on lidar generally uses the lidar to scan the 3D scene, uses the principle of laser ranging, records the depth information of a large number of dense points on the surface of the measured object, and uses the 3D reconstruction algorithm to realize 3D modeling. However, both have the following disadvantages: the modeling time is long, up to one week, and it...
