| Abstract | Airborne laser scanner is useful system for acquiring point clouds 3D data with real-time, and it came to be generally used in the late 1990s. Airborne laser scanner have effectiveness in extracting micro topography or ground surface under the trees which are not detect by photogrammetry, and many applications such as city modelling, DTM generation, monitoring electrical power lines and detection of forest areas were proposed. The most remarkable point of this system, however, is its ability to obtain 3D coordinates of huge object points with real-time. Airborne Laser Scanner is basically based on GPS, inertial measurement unit (IMU) and laser scanning device (Laser Rangefinder). GPS and IMU provide position and attitude information regarding trajectory of platform, and laser scanning device give distance between platform and the object points. Therefore, direct-georeferencing system using GPS/IMU comes to be utilized widely in the field of aerial photogrammetry, nevertheless matching among stereo models and courses are not adjusted since the direct-georeferencing system are influenced by cycle-slip and satellite placement. This paper investigates fundamental studies to improve of accuracy of airborne laser scanner data using digital images. |
