APPRATUS AND METHOD FOR GENERATING DIGITAL ELEVATION MODEL USING LIDAR

摘要

PURPOSE: An apparatus for generating digital elevation model using LiDAR is provided to exactly embody 3D geographical information, and construct structural feature data. CONSTITUTION: A first and a second LiDAR are installed to a bottom side of an aircraft. A coordinate corresponding to each scanning area is calculated. One side of the ground is scanned by the first LiDAR based on the side scanning to the ground(S309). The second LiDAR scans the other side of the ground(S313). Based on the coordinate information, 3D elevation model is generated(S317).
