Abstract

The invention discloses a method for fast identifying a building image on the basis of morphology. The method fully utilizes a morphological characteristic, different from those of other natural objects, of a building and is used in a building image fast identifying system. After image object contour tracking and linear simplification interference-removing processing is performed, whether the building exists in an image is fast and accurately determined by a horizontal and vertical topological relation of the building. Thus, the building is identified.

Description

technical field

[0001] The invention relates to a method for quickly recognizing building images based on morphology, which belongs to the field of geographic information science. Background technique

[0002] When carrying out land monitoring of national land resources, it is often necessary to identify whether the monitoring area of ​​the camera is land, farmland or buildings. The traditional and general methods are based on remote sensing recognition and texture feature recognition, and these two recognition methods are real-time. There is a big problem, based on remote sensing data, the speed is slow and the efficiency is low; when recognizing building images based on texture features, the speed is slow and the stability is poor, and it is easily affected by other external environmental changes and light, and the robustness is not good.
