摘要:Laser Scanner can measure the direct distance from the aircraft to the terrain surface by run-time emitting and reflecting laser pulse. DEM can be available with lower costs and sort period than other ways. IKONOS Satellite can get high resolution image. Combining DEM from Laser Scanning and texture from IKONOS image in the same region can provide a low-cost way to realize 3D-visualization to a certain extent. Registering IKONOS image and LIDAR image is the most important procedure. Two algorithms are adopted in the registration of IKONOS image as texture information and LIDAR image as three-dimensional spatial inform
