Urban water body remote sensing classification method and device

The invention provides an urban water body remote sensing classification method and device, and relates to the technical field of remote sensing image processing. The method specifically comprises the steps: preprocessing an obtained remote sensing image, and extracting an urban water body from the preprocessed remote sensing image; calculating XYZ tristimulus values of the CIE of the urban water body; judging whether the Y stimulus value is greater than a preset optimal space-time adaptive threshold value or not; if yes, calculating the chromaticity angle of the urban water body based on XYZ tristimulus values of CIE, and conducting secondary correction on the chromaticity angle; comparing the obtained secondarily corrected chromaticity angle with a plurality of preset threshold intervals to obtain a threshold interval to which the secondarily corrected chromaticity angle belongs, thereby determining the type of the urban water body, the type at least comprising a clean water body, a cleaner water body, a ge
