An Automatic Building Density Extraction Method and Application for Radio Propagation Model

  • Radio transmission path has a variety of interference and building on the transmission path is one of great influence factor. In order to reduce building effect on the prediction accuracy of radio propagation model, GB/T 14617.1—2012 Propagation characteristics in land mobile service and fixed servicePart 1:Propagation characteristics in land mobile service, introduced the building density correction factor. But the geographic information system does not provid the building density. Therefore, this paper proposes a method using satellite image spectrum characteristic and digital image processing technology to identify buildings and automatically extract the building density. We carried out comparative analysis experiments with threshold method and K-Clustering method and the research results show that this method can calculate the density of buildings quickly and accurately from the satellite images, and significantly improve the accuracy of the radio propagation model.
