Abstract

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.

Dependent claims

A method for determining types of ice-and-snow cover, comprising:

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 data base of typical types of ice-and-snow cover;
and
extracting RGB component values of an ice-and-snow covering point from an ice-and-snow cover image of a measurement area, comparing the RGB component values of the ice-and-snow covering point with the typical RGB component values in the database of typical types of ice-and-snow cover, and determining a type of ice-and-snow cover of the measurement area according to a comparison result.

A device for determining types of ice-and-snow cover, comprising:

an establishing module for a database of typical types of ice-and-snow cover, which is configured to determine typical RGB component values of typical types of ice-and-snow cover, establish a one-to-one corresponding relation between the typical types of ice-and-snow cover and the typical RGB component values, and establish the database of typical types of ice-and-snow cover;
and
a determination module for a type of ice-and-snow cover of a measurement area, which is configured to extract RGB values of an ice-and-snow covering point from an ice-and-snow cover image of the measurement area, compare RGB component values of the ice-and-snow covering point with typical RGB component values of the types of ice-and-snow cover, and determine the type of ice-and-snow cover of the measurement area according to a comparison result.
