Abstract

The invention discloses an automatic and rapid extraction method and device for newly added human activity plaques on the ocean red line, belonging to the field of environmental monitoring. In this method, the background vector is used to segment the background image and the image to be detected, and the segmented plaques are discriminated one by one by using the luminance statistical value and the spectral feature function to obtain the changed plaque and the suspected changed plaque; the suspected changed plaque and the local The patches corresponding to the bottom image are segmented twice according to the characteristics of spectrum, geometry, and texture, and the segmented patches are identified one by one by using the luminance statistical value and the spectral feature function to obtain the changed patches; all the changed patches are combined to obtain a new Increase the number of human activity patches; make statistics on the newly added human activity patches, and obtain the number and area of ​​the newly added human activity patches within the ocean red line. The invention can automatically and quickly extract information such as the position, quantity and distribution area of ​​newly added human activity patches in the ocean red line, and provide fast and accurate technical support for the supervision of human activities on the ocean red line.

Description

technical field [0001] The invention relates to the field of environmental monitoring, in particular to an automatic and rapid extraction method and device for newly added human activity plaques on ocean red lines. Background technique [0002] With the development of economy and society, people's yearning for a better ecological environment continues to increase. However, driven by economic interests, there are always various human activities that damage the ecological environment. Ocean red line (also known as marine ecological red line, ocean red line) refers to the geographical area boundary and related management indicators formed by dividing areas with special important ecological functions within the scope of marine ecological space that must be strictly protected as key control areas. control line. The ocean red line is the bottom line and lifeline for guaranteeing and maintaining marine ecological security, and it is necessary to detect behaviors that violate the ...
