Building feature extraction method and system based on three-dimensional modeling and storage medium

Abstract

The invention relates to a building feature extraction method and system based on three-dimensional modeling and a storage medium. The building feature extraction method based on three-dimensional modeling comprises the steps of acquiring orthoimage and inclined images and preprocessing the images; performing three-dimensional modeling on acquired images. The invention also comprises a building feature extraction system based on three-dimensional modeling, and the system comprises an obtaining unit which is used for obtaining orthoimage and an inclined images, and preprocessing the images; anda processing unit used for carrying out three-dimensional modeling on the preprocessed images. According to the invention, a technical means of feature extraction, filling and identification after three-dimensional modeling of the images is adopted. The technical problems that in the prior art, it is difficult to extract a static target through the two-dimensional images, and an image analyzing and processing method of a moving target cannot be used for positioning and segmenting a static building are solved. The beneficial effects of reducing the difficulty of static target feature extraction and applying the image analysis and processing method of the moving target to positioning and segmentation of the static building are achieved.

Description

technical field

[0001] The invention relates to a high-precision real-time three-dimensional reconstruction method at a mobile terminal, in particular to a building feature extraction method, system and storage medium based on three-dimensional modeling. Background technique

[0002] In my country's urban management work, urban construction supervision is an important function, and it is responsible for the important task of comprehensive supervision of urban buildings. In order to grasp the changes in the city and implement effective management, the urban authorities, including planning, design, construction and other departments, urgently need to dynamically grasp the information of the city's building area and land area. With the rapid development of urbanization in our country, due to various reasons, there are a large number of illegal buildings in urban buildings. How to quickly and accurately obtain urban building information is a challenge faced by urban construction...
