Method and system for classifying a terrain type in an area

摘要

A method for classifying a terrain type in an area is provided, which method comprises the steps of: obtaining a plurality of overlapping aerial images of the area; calculating at least one terrain type index for each part of each of the aerial images which lies in the area, where the at least one terrain type index represents the terrain type; determining at least one terrain type index for each part of the area based on the calculated at least one terrain type index for each part of each of the aerial images; and classifying the parts of the area for which at least one pre-determined conditions is met as containing the terrain type, wherein at least one of the at least one predetermined condition relates to a value of the determined at least one terrain type index. An associated system and computer program product are also provided.

1. Method for classifying a terrain type in an area, the method comprising the steps of:
obtaining a plurality of overlapping aerial images of the area, said plurality of overlapping aerial images each containing at least one common part; calculating at least one terrain type index for each common part of each of the aerial images which lies in the area, where the at least one terrain type index represents the terrain type for each common part in each of the aerial images; determining at least one effective terrain type index for each common part, said at least one effective terrain type index being calculated based upon a statistical average of each of the at least one terrain type index calculated for each common part of each of the aerial images; and classifying the common parts of the area for which at least one pre-determined conditions is met as containing the terrain type, wherein at least one of the at least one predetermined conditions relates to a value of the determined at least one effective terrain type index.
