Yangtze River midstream coastal forest land information extraction system based on multi-level classification model

Abstract

The invention discloses a Yangtze River midstream coastal forest land information extraction system based on a multi-level classification model, and the system comprises an image collection module, atemperature and humidity collection module, an information processing module, a central database, an information comparison module, and an information integration module. An output end of the image collection module is connected with an input end of the information processing module. The output end of the temperature and humidity collection module is connected with the input end of the informationprocessing module, the information processing module is connected with the central database, the output end of the information processing module is connected with the input end of the information comparison module, and the output end of the central database is connected with the input end of the information comparison module. An output end of the information comparison module is connected with aninput end of the information integration module. Information extraction speed is effectively improved, extraction of information is further accelerated by utilizing huge data in a central database through comparative analysis, and the finally obtained information is more accurate.

Description

technical field [0001] The invention belongs to the technical field of information extraction, in particular to a forest land information extraction system along the middle reaches of the Yangtze River based on a multi-level classification model. Background technique [0002] The Yangtze River (English name: the Changjiang River / the Yangtze River) originates from the "roof of the world" - the southwest side of Geladandong Peak in the Tanggula Mountains on the Qinghai-Tibet Plateau. The main stream flows through 11 provincial-level administrative regions (eight provinces, two cities and one district) in Qinghai Province, Tibet Autonomous Region, Sichuan Province, Yunnan Province, Chongqing City, Hubei Province, Hunan Province, Jiangxi Province, Anhui Province, Jiangsu Province, and Shanghai City. It flows into the East China Sea to the east of Chongming Island, with a total length of 6,397 kilometers. Among the world's largest rivers, it is second only to the Nile River in Af...

Problems solved by technology

[0003] However, the middle reaches of the Yangtze River are prone to disasters during the flood season, and the forests along the middle reaches of the Yangtze River can often be used to determine the coming of the flood season based on geological or other information. The later information processing is too slow and cause serious consequences
