Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0022] refer to figure 1 Shown, a kind of urban landscape water body color quantitative classification method of the present invention comprises the following steps:

[0023] Step 1: After radiation calibration, the color values ​​of the water surface and water bodies at different depths under the water surface are respectively extracted, and the color values ​​RGB are converted into HSB color space, and the colors H, S, and B value;

[0024] Step 2, obtain the water surface color B value information of all water bodies, and divide the water bodies within the same preset B value range into the same color group to obtain at least one B value color group;

[0025] Step 3: Obtain t...

Abstract

The invention discloses a method for quantitatively classifying colors of urban landscape water body, wherein, by acquiring the values of the color H, S, B, different components are respectively selected as classification standards according to the HSB color value components, and finally the water colors are quantitatively classified.

Description

technical field [0001] The invention relates to the technical field of color classification of landscape water bodies, in particular to a method for quantitatively classifying the color of urban landscape water bodies. Background technique [0002] Urban landscape water refers to rivers flowing through cities, lakes and reservoirs in urban areas, park water systems, artificial canals and artificial lakes, etc. Inorganic urban water bodies are generally yellow or khaki, and the content of inorganic particles such as clay and silt is relatively high , usually canal water flowing through the city. At present, with the road network and people's pursuit of quality of life, the shipping function of canal water is gradually weakened, and the landscape and ecological functions are gradually highlighted. However, with the rapid development of urbanization and industrialization in our country, the canal, as the storage body of urban domestic sewage and industrial wastewater, has low ...
