Error of the laser scanning system and noise of the laser measuring data were analyzed by using the data processing technology such as data reduction, de-noising, coordinate transformation, distance compensation. The laser scanning data of airplane parking was obtained after field test of an airport. The results show that airplanes can be parked accurately through processing of laser scanning data, and he distance between stop line and plane can be assured to less than 100mm.
