Abstract

The invention provides a building modeling method and device. The method includes the steps that airborne LIDAR data are preprocessed, and building point cloud information is extracted in non-ground points; the point cloud information is partitioned to obtain a building object; building regular frames are extracted; roof points are classified according to surface patches; a building model is established according to the classification result; the effect of the established model is displayed. By means of the building modeling method and device, the precision of the building model is greatly improved, and the degree of automation of building extraction is further improved.

Description

technical field [0001] The invention relates to satellite remote sensing and graphic modeling, in particular to a building modeling method and device based on airborne laser radar. Background technique [0002] The rise of LiDAR (Light Detection And Ranging, LIDAR for short) technology provides a new option for solving the problem of how to quickly obtain data. Lidar technology is an active information acquisition technology. It has been developed for many years since its appearance, and it has gradually emerged and received more and more attention from related industries. LiDAR measurement technology is a new technology that emerged and gradually developed from the middle and late 20th century. The airborne LIDAR system is an integrated system that includes multiple devices, mainly including laser ranging unit, optical mechanical scanning unit, and control recorder. unit, GPS receiver and inertial measurement unit IMU (InertialMeasure Unit), etc., where the laser ranging u...
