Embodiment Construction

[0081] Below, the present invention will be described in detail with reference to the accompanying drawings.

[0082] Such as figure 1 As shown, the present embodiment provides an image-based automatic monitoring method for illegal buildings, which includes the following four steps:

[0083] Step 1. UAV aerial image preprocessing

[0084] 1) Generate digital surface model and digital orthophoto map

[0085] UAV aerial images are used to generate digital surface model DSM and digital orthophoto map DOM. This step can be completed by commercial software such as Inpho, Erdas and open source software.

[0086] 2) Eliminate vegetation areas

[0087] Use image processing software to eliminate vegetation areas in DSM and DOM, and retain building areas. This step can be completed with commercial software such as eCognition and ENVI.

[0088] 3) Generate a textured DSM and build a paging level of detail model

[0089] Map the digital orthophoto map DOM to the digital surface model...

Abstract

The invention provides an automatic illegal building monitoring method based on an image and a realization system thereof. Through processing of an image, registration of digital surface models (DSM) of different phases, detection of elevation changes and confirmation of an illegal building, the problem that the building elevation changes are neglected based on spectral features or texture features in the prior art is solved, the automatic illegal building monitoring method based on the image carries out monitoring in a three-dimensional image mode, the monitoring precision is high, the monitoring is not influenced by environmental factors such as shadows and weather and error judgment is not likely to happen.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle images and high-resolution satellite remote sensing image interpretation, in particular to an image-based automatic monitoring method for illegal buildings and its implementation system. Background technique [0002] With the further advancement of urbanization, industrialization and information in our country, the degree of development and utilization of construction land is increasing. Illegal occupation of land and illegal buildings are very common, seriously affecting the rational and effective use of land and the sustainable development of cities. Urban management poses great obstacles. Real-time, dynamic and accurate grasp of urban construction land, and use the current situation and building changes to quickly discover illegal buildings and stop illegal construction behaviors in a timely manner. necessary prerequisites for implementation.
