Embodiment 1

[0087] An embodiment of the present invention provides an automatic and rapid extraction method for newly added human activity plaques in the ocean red line, which is used to automatically obtain the newly added human activity plaques in the ocean red line, and obtain the location, quantity and distribution area of ​​the newly added human activity plaques in time , which aims to solve the problem of low efficiency and slow speed in the extraction of human activity information in ocean red line supervision mainly relying on human-computer interaction interpretation. The invention can perform fully automatic, accurate and rapid extraction of human activity plaques, and provides technical support for the supervision of human activities on ocean red lines.

[0088] Such as figure 1 As shown, the method includes:

[0089] S1: Obtain the image to be detected, background data, background image and red line vector, where: the image to be detected is a high spatial resolution remote s...

Embodiment 2

[0155] An embodiment of the present invention provides an automatic and rapid extraction device for newly added human activity plaques on the ocean red line, such as figure 2 As shown, the device includes:

[0156] The data acquisition module 1 is used to obtain the image to be detected, the background data, the background image and the red line vector, wherein: the image to be detected is a high spatial resolution remote sensing image of the area to be detected, and the background data is the historical background of human activity classification Data, the background image is the high spatial resolution remote sensing image corresponding to the background data, and the red line vector is the ocean red line vector data.

[0157] The mask processing module 2 is configured to use the red line vector to perform mask processing on the image to be detected and the background image respectively.

[0158] The transformation module 3 is used for performing raster-vector transformati...

Abstract

The invention discloses a method and a device for automatically and quickly extracting newly-added human activity plaques on a marine red line, and belongs to the field of environmental monitoring. The method comprises the following steps: segmenting a background image and a to-be-detected image by utilizing a background vector, and judging segmented plaques one by one by utilizing a brightness statistical value and a spectral characteristic function to obtain changed plaques and suspected changed plaques; carrying out secondary segmentation on the suspected changed plaques and plaques corresponding to the background image according to the characteristics of spectrum, geometry, texture and the like, and judging the segmented plaques one by one by utilizing a brightness statistical value and a spectrum characteristic function to obtain changed plaques; merging all the changed plaques to obtain newly added human activity plaques; and counting the newly added human activity plaques to obtain the number and area of the newly added human activity plaques in the ocean red line. The method can automatically and quickly extract the position, number, distribution area and other informationof the newly added human activity plaques in the marine red line, and provides quick and accurate technical support for marine red line human activity supervision.

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 ...
