Method and device for determining types of ice-and-snow cover

Provided is a method for determining types of ice-and-snow cover. The method includes: determining typical RGB component values of typical types of ice-and-snow cover, establishing a one-to-one corresponding relation between the typical types of ice-and-snow cover and the typical RGB component values, and establishing a database of typical types of ice-and-snow cover; and extracting RGB values of an ice-and-snow covering point from an ice-and-snow cover image of a measurement area, comparing RGB component values of the ice-and-snow covering point with typical RGB component values in the database of typical types of ice-and-snow cover, and determining the type of ice-and-snow cover of the measurement area according to a comparison result.
