Abstract

The present invention discloses an apparatus for obtaining water quality information, a method ans system for recognizing water body eutrophication degree. The apparatus includes LED lamps arranged around a filter uniformly for emitting given wavelengths; a filter for blocking light beams except the given wavelengths to collect an optical image; and a CCD light sensor for transforming the opticalimage transmitted to the surface of the CCD light sensor into an electric signal. The technical scheme of the invention is capable of rapidly, high efficiently and conveniently obtaining images with high space resolution and high time resolution, and implementing multidata monitoring and evaluation of the water body entrophication by processing and analyzing the image. The cost of the apparatus islow, and operation is convenient. The invention is capable of replacing laboratory analysis methods or providing assistant support for the laboratory analysis methods, arranging sampling points reasonably and reducing the usage of chemical agents, and overcoming abuses caused by collecting data using remote sensing satellites.

Description

technical field [0001] The invention relates to the field of water body eutrophication research, in particular to a real-time water quality information acquisition device for identifying water body eutrophication degree, and a water body eutrophication degree identification method and system based on image processing technology. Background technique [0002] The eutrophication incidents of lakes in my country have frequently broken out in recent years, which has brought certain constraints to the ecological environment of lake water, the living environment of residents, and economic development. From a national perspective, urban lakes are already in a state of severe eutrophication or moderate eutrophication, and most large and medium-sized lakes have already met the conditions for eutrophication or are in a state of eutrophication. Taihu Lake, Chaohu Lake, Dianchi Lake Wait for the frequent outbreaks of blue-green algae. After the eutrophication of fresh water, the "algae...
