Surface environment change monitoring method and device, readable storage medium and equipment

Abstract

The invention discloses a surface environment change monitoring method and device, a readable storage medium and equipment, and belongs to the technical field of remote sensing. The method comprises the steps of: obtaining time sequence NDVI remote sensing image data and land utilization type data; according to the land utilization type data, obtaining an average NDVI time sequence curve of each land utilization type; calculating the similarity between each pixel on the NDVI annual time sequence image and each land utilization type; setting specific surface environment type transformation scenes in two years, and calculating the sum of the similarity of one class of the reference year and the similarity of the other class of the monitoring year; and carrying out threshold segmentation on a similarity sum result image, and extracting a region with a relatively large pixel value, so that a surface environment change region of a specific conversion type can be obtained. According to the method, the similarity is calculated for the specific land surface environment type, specific target features and change features are highlighted to the maximum extent, specific land change types are rapidly and accurately extracted in a targeted mode, and technical support is provided for ecological environment supervision.

Description

technical field [0001] The invention relates to the technical field of remote sensing, in particular to a method, device, readable storage medium and equipment for monitoring changes in the surface environment. Background technique [0002] Human activities often cause changes in the surface ecological environment, especially activities such as deforestation, lake reclamation, and illegal reclamation and construction have adverse effects on the ecological environment and global climate change. It is very important for the ecological environment management department to timely and accurately obtain the change status of the surface ecological environment and take timely response measures to abnormal changes. [0003] At present, the change monitoring method based on time-series remote sensing images has become an important means of surface environment change monitoring. However, the existing methods focus on the construction of change monitoring operators. Usually, the same s...

Problems solved by technology

However, the existing methods focus on the construction of change monitoring operators. Usually, the same set of change monitoring operators is used to comprehensively extract multiple change types, which often results in some change types being covered up by other pseudo changes, making it difficult to be accurately detected.

Ecological and environmental management departments often only focus on one or several specific types of changes, such as lake reclamation, ecological conservation forest destruction, etc. Existing methods are slightly insufficient in application pertinence and operating efficiency
