Abstract

The invention belongs to the field of environmental geological survey, particularly relates to an environmental geology survey method based on high-altitude remote sensing and low-altitude unmanned aerial vehicle oblique photography, and aims to solve the problems that environmental geological survey is inconvenient, survey efficiency is low and manpower is wasted in the prior art, and the method comprises the following steps of: S1, acquiring a high-altitude remote sensing image; S2, delineating a geological environment problem area; S3, acquiring high-altitude remote sensing images in different time periods, and investigating historical change conditions of the images; S4, performing low-altitude unmanned aerial vehicle aerial photography on the delineated geological environment problem area; and S5, determining the current situation, range, form and later development trend of environmental problems, and forming a topographic map or a three-dimensional diagram. According to the method, the environmental current situation of a research area in different periods is determined through high-altitude remote sensing images, meanwhile, the specific environmental current situation of the research area is determined through aerial photography of a low-altitude unmanned aerial vehicle, and a topographic map is made for later scheme design and governance engineering service; environmental geological survey can be effectively carried out, manpower is saved, and efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of environmental geological survey, in particular to an environmental geological survey method of high-altitude remote sensing and low-altitude unmanned aerial vehicle oblique photography. Background technique [0002] Environmental geological survey is to evaluate and predict the environmental geological conditions of resource development and land consolidation through the investigation and research of regional geological environmental conditions and environmental geological problems caused by natural geological processes and human activities, and to demonstrate major regional environmental geological problems and related geological disasters. Based on the background of the geological environment, the countermeasures for the protection of the geological environment are drawn up to provide a scientific basis for the sustainable development of the regional economy and society, the construction of the ecologica...
