Problems solved by technology

[0004] Due to the complex and diverse environment of urban buildings, there are great difficulties and interferences in the extraction of buildings. At present, the extraction accuracy of object-oriented buildings based on samples alone is low, and the extraction of object-oriented buildings based on rules alone is easy to extract some gray buildings. Confused with dark toned bare ground and asphalt roads

Embodiment

[0067] see figure 1 , figure 1 It is a schematic flowchart of the building information extraction method based on rule and sample fusion in the embodiment of the present invention.

[0068] Such as figure 1 As shown, a method for extracting building information based on rule and sample fusion, the method includes:

[0069] S11: Acquire worldview2 monolithic data in the corresponding area, the worldview2 monolithic data includes 1.8m multispectral data and 0.5m panchromatic band data;

[0070] In the specific implementation process of the present invention, it is necessary to crawl the worldview2 monolithic data in the corresponding database that needs to carry out the building information extraction area, and the worldview2 monolithic data includes multispectral data of 1.8m and panchromatic band data of 0.5m; wherein In addition to the four common bands (Blue, Green, Red, NIR1), multispectral data has four additional bands: CoastalBlue, Yellow, RedEdge, Near Infrared 2 ba...

Abstract

The invention discloses a building information extraction method and system based on rule and sample fusion, and the method comprises the steps: obtaining worldview 2 single-chip data of a corresponding region; preprocessing the extracted worldview2 single-chip data, so as to obtain the preprocessed worldview2 single-chip data; according to the preprocessed worldview 2 single-chip data, carrying out object-oriented building information extraction based on samples, and obtaining first building area information; performing rule-based object-oriented building information extraction according to the preprocessed worldview 2 single-chip data to obtain second building area information; and fusing the first building area information and the second building area information to obtain building areafusion extraction information. In the embodiment of the invention, the building without obvious errors is extracted, and the building is good in intuitive feeling, clear in contour and regular in shape.

Description

technical field [0001] The invention relates to the technical field of urban building information extraction, in particular to a building information extraction method and system based on fusion of rules and samples. Background technique [0002] With the development of urban construction and the continuous improvement of the level of urbanization, urban construction land shows a high growth trend; the expansion of construction land has a certain impact on the social and ecological environment; and buildings are the most important targets in construction land The information extraction and accurate identification of ground objects are hot issues in urban remote sensing research; on the one hand, the rapid acquisition of buildings helps city managers to manage and plan the city, productivity layout, and three-dimensional modeling of the city. On the one hand, it is of great significance to the protection and sustainable use of land resources. [0003] At present, there are t...
