Description
Technical field
The present invention relates to landscape water body color extraction technical fields, and in particular to a kind of city appearance water body color extraction dress
It sets and extracting method.
Background technique
City appearance water body refers to lake and reservoir, park water system, artificial canal and the people in the river, city that flow through city
Work lake etc., for two inorganic type urban water-bodies generally in yellow or khaki, the inorganic particulate matters content such as clay, silt is higher, leads to
The often Canal-water to flow through city.Currently, the pursuit with highway networking and people to quality of the life, the navigation function of Canal-water
It is gradually weakened, landscape and ecological functions highlight gradually.But with China's urbanization, industrialized fast development, canal is made
For the packaging container of city domestic sewage and industrial wastewater, transparency is low, color exception, and has peculiar smell, and water body apparently pollutes
Seriously.
In the prior art, there is subjectivity for the evaluation of apparent quality of landscape water body, by object of reference, time, place
It needs related with apparatus measures water body with the influence of environment etc. therefore in order to objectively evaluate the apparent mass of landscape water body
Parameter establishes the representation method of quantitative description water body apparent mass, obtain landscape water body apparently change objectively evaluate and
The method of record forms the standard measured and judge treating landscape water body effect accordingly.Due to solubilised state non-in city appearance water body
Particulate matter is the main reason for causing water body apparently to pollute, and the composition and content of particulate matter decide that the color of water body is special simultaneously
Property, therefore it is particularly significant to the extraction of city appearance water body color, in the apparent pollution index SPI finding process of city appearance water body
In, water body color is one of influence factor, and currently, the differentiation to color is mainly carried out using artificial, human subjective's judgement is logical
Often lack accuracy, has larger impact to the acquisition of final apparent pollution index.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of dresses for capableing of objective acquisition city appearance water body color index
It sets, and the method that water body color is extracted using this device, solves apparent pollution index and need artificial cognition color
The drawbacks of, eliminate the influence that subjective judgement obtains apparent pollution index.
In order to solve the above-mentioned technical problems, the present invention provides a kind of city appearance water body color extraction devices, including branch
