<P>PROBLEM TO BE SOLVED: To quickly grasp topographical variation caused by occurrence of a disaster by simplifying data processing and shortening processing time when acquiring topographical information by loading a laser range finder or the like on an aircraft. <P>SOLUTION: An airborne laser survey system includes: laser range finding means for measuring distances of laser irradiation points of a plurality of laser range finders loaded on the aircraft and fixed so that angles of laser emission directions of respective laser range finders are shifted; and position calculation means for calculating a three-dimensional position of each laser irradiation point by combining position information received by a GPS receiver and posture information obtained by an IMU with range finding data acquired by the laser range finding means, to read out topographical information on a plurality of lines parallel with a flying line of the aircraft and quickly grasp topographical variation caused by the occurrence of the disaster. <P>COPYRIGHT: (C)2013,JPO&INPIT |
