Embodiment Construction

[0038] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure. And, the first, second, third, etc. descriptions used in the present disclosure are only used for distinction, and do not represent the actual sequence.

[0039] Before introducing the method of the present disclosure, the application scenarios of the present disclosure are briefly described. When performing 3D reconstruction of a building, it is generally necessary to take a top view of the building, so that the contour of the building in the top view of the building is used to call the corresponding contour model from the model library, so as to realize the 3D reconstruction of the building. However, for a building without a corresponding outline model in th...

Abstract

The invention relates to an image processing method and device, a storage medium and an electronic device, and aims to solve the problem of low manual modeling efficiency in the prior art. The methodcomprises the steps of determining a contour of a target building according to a top view of the target building; determining available pixel points of a target contour, wherein the initial target contour is the contour of the target building; according to the available pixel points, determining whether a target cutting line exists or not, and in two sub-contours obtained after the target contouris cut through the target cutting line, the sub-contour with the smaller area is matched with a contour model stored in a model base; if the target cutting line exists, cutting the target contour by using the target cutting line to obtain a first sub-contour and a second sub-contour, and storing the first sub-contour with a smaller area as the target sub-contour; judging whether a contour model matched with the second sub-contour exists in a model library or not; and if the matched contour model exists, storing the second sub-contour as a target sub-contour, and stopping cutting.

Description

technical field [0001] The present disclosure relates to the field of image processing, and in particular, to an image processing method, device, storage medium, and electronic equipment. Background technique [0002] With the development of computer technology, more and more construction-related work uses computer technology, and gradually shifts from two-dimensional architectural plans to three-dimensional architectural models. At present, when performing 3D reconstruction on a building, the building is generally matched with an existing 3D model in a model library to complete the 3D reconstruction of the building. However, the 3D model styles in the model library are limited. If a building is to be reconstructed in 3D, but no suitable 3D model can be found in the model library, it is necessary to manually model the building, which will cost a lot of manpower cost, and the modeling efficiency is not high enough. Contents of the invention [0003] The purpose of the pre...
