Fast extraction method of suspected illegal land use information based on unmanned aerial vehicle images

Abstract

The invention provides a method for quickly extracting suspected illegal land use information based on unmanned aerial vehicle (UAV) images. (2) Enhancement and transformation of unmanned aerial vehicle images; (3) Object-oriented land use information change detection method; (4) extracting new land change patches; (5) Extracting the information of suspected illegal land use. Advantages: based onspatial information technology, deepening and expanding geographical matching, data splicing, image enhancement change, a method for processing image data and extracting information of unmanned aerialvehicle includes detecting information change, combined with the spatial analysis model of GIS, this paper realizes the comparative analysis between multi-source and multi-temporal remote sensing data and between remote sensing image data and urban construction planning approval data, quickly obtains the suspected illegal land use situation, and provides technical services and decision-making basis for urban land resources monitoring and management.

Description

technical field [0001] The invention relates to a method for quickly extracting land use information suspected to be in violation of laws and regulations based on drone images, and belongs to the technical field of signal and information processing. Background technique [0002] Land resources are the environmental resources and material basis for the survival and development of human beings. The degree of utilization and development trend of their development will directly affect the integrated and coordinated development of the social economy. Therefore, the dynamic supervision of land use and the investigation and punishment of illegal land use are the key factors in my country's current land resources management. key work. With the intensification of my country's urbanization process and the continuous expansion of urban space, the demand for urban construction land has increased significantly, the contradiction between supply and demand of land resources has continued to...

AI Technical Summary

Problems solved by technology

Affected by many factors such as remote sensing sensors and carrying platforms, remote sensing data acquisition methods, and processing methods, coupled with the fact that land use monitoring has a strong purpose and current situation, the results of remote sensing monitoring are important in the process of routine land use monitoring work. Failed to fully deepen and expand

At the same time, the current means and technologies of land use monitoring are still at a relatively low level, and there are many problems, which limit the further development of supervision work.
