Embodiment

[0043] Such as figure 1 As shown, it is a schematic flow chart of the present invention, which mainly includes the following seven steps: data selection, data preprocessing, principal component analysis, image segmentation, spectral change vector construction, spectral change degree measurement, post-processing, and each step is as follows Explain in detail.

[0044] S1. Data selection

[0045] According to the monitoring time period of interest, two phases of multi-spectral remote sensing images are selected. When selecting data, it is necessary to combine the natural climate characteristics of the monitoring area and the scale size and temporal and spatial distribution characteristics of human activities of concern to select appropriate remote sensing images. Try to choose good-quality remote sensing images to reduce the interference of clouds, snow, fog, shadows, etc., and try to select remote sensing images from the same sensor to avoid the influence of chromatic aberrati...

Abstract

The present invention proposes a method for detecting changes in human activities in nature reserves based on multi-scale feature fusion, which can serve the monitoring business of human activities in nature reserves, improve the work efficiency of monitoring business changes in human activities in nature reserves, and reduce work costs. The detection method of the present invention mainly includes seven steps of data selection, data preprocessing, principal component analysis, image segmentation, spectral change vector construction, spectral change degree measurement, and post-processing, and then extracts the final changed object. Due to the improvement of work efficiency, the detection method of the present invention can detect human activities existing in the natural protection area in a more timely manner, realize early detection and early treatment of human activities, so as to better protect the natural protection area and ensure the safety of the national ecological environment .

Description

technical field [0001] The invention belongs to the technical field of ground monitoring and ecological environment protection, and relates to a detection method for human activity changes in nature reserves based on multi-scale feature fusion. Background technique [0002] Remote sensing change detection is based on observations of the same object or phenomenon at different times to determine its different processing procedures. Remote sensing image change detection is the use of multi-source remote sensing images and related geospatial data covering the same surface area in different periods, combined with the corresponding features and remote sensing imaging mechanism, to determine and analyze the changes of the region and features, including the location and range of the features. Changes and changes in feature information and status. Its purpose is to find out the change information of interest and filter out irrelevant change information as interference factors. Remo...
