Embodiment 1

[0032] Such as figure 2 As shown, in order to realize timely and automatic monitoring of illegal construction development, the present invention proposes an automatic detection method for illegal construction land development based on multi-source optical remote sensing images, including the following steps:

[0033] S1: Obtain optical remote sensing images of the area to be detected at two different times;

[0034] It should be noted that two optical remote sensing images corresponding to different times can be acquired by the same satellite or by different satellites.

[0035] S2: Calculate the land leveling intensity between two optical remote sensing images at different times to obtain a land leveling intensity image;

[0036]It should be noted that the development of construction land generally begins with the leveling of the land. The main purpose of leveling is to remove existing vegetation, buildings and other obstacles on the land to be developed, so as to facilitat...

Abstract

The invention discloses an automatic detection method for illegal construction land development based on multi-source optical remote sensing images. Intensity, to obtain the land leveling intensity image; use the maximum expectation algorithm to cluster the land leveling intensity image, extract the corresponding area of ​​construction land development in the area to be detected; compare the extracted area corresponding to the development of construction land with the land planning of the area to be detected , Land planning strictly prohibits the development of construction land in the development area, which is illegal construction land development. The present invention can carry out short-period, fully automatic monitoring of illegal construction land development, simple calculation, easy to understand, high execution efficiency, and does not require any training samples, and can timely discover and prevent various social and environmental problems caused by illegal construction land, and Significantly reduce monitoring costs and improve monitoring efficiency.

Description

technical field [0001] The invention relates to the technical field of remote sensing image processing, and more specifically, to an automatic detection method for illegal construction land development based on multi-source optical remote sensing images. Background technique [0002] Illegal construction land has become one of the main problems faced by land use in my country's social and economic transition period, and poses a severe challenge to new urbanization and ecological civilization construction. According to the China Land and Resources Bulletin, from 2012 to 2016, a total of 390,000 illegal land use activities were discovered across the country, involving a land area of ​​175,500 hectares. Illegal land use for construction has exacerbated the disorderly expansion of the city, not only undermining the overall coordination and comprehensive development of the city, but also encroaching on a large amount of high-quality farmland, resulting in the continuous shrinking...
