Abstract

The present application discloses a building information extraction method, device and computer equipment, which relate to the field of computer technology and can solve the problems of inaccurate extraction results and incomplete information coverage when extracting building information. The method includes: acquiring the airborne lidar LiDAR data of the area to be monitored in real time; separating non-ground points from the preprocessed LiDAR data according to a point cloud filtering algorithm; using the non-ground points to extract the data in the area to be monitored Building outline; determining building information of the to-be-monitored area based on the building outline. This application is suitable for the extraction of building information.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular, to a method, device and computer equipment for extracting building information. Background technique [0002] Building information plays an important role in applications such as military reconnaissance, geographic information system (GIS) data update, urban planning, disaster prevention, resource survey, and digital city construction. With the development of remote sensing technology, a large amount of remote sensing data becomes possible. However, in ordinary RGB remote sensing images, it is difficult to extract building information due to the complex background of roads and squares. Therefore, developing reliable and accurate building extraction methods has become an important and challenging research topic. [0003] In the past few decades, many building extraction studies have been based on traditional image processing methods. In feature engineering, the tr...
