An efficient automated extraction algorithm of power lines based on Airborne Laser Scanning(ALS) data was put forward.The algorithm adopted point clouds classification based on region part height histogram distribution patterns,lines extraction method with global direction feature in Hough space,mathematical estimating method of hanging point position and local partitioned polynomial fitting method.Four key problems were solved by use of the algorithm,namely,point clouds classification,plane pos...
