飞机泊位系统中的激光扫描数据的处理

摘要

为了实现飞机泊位系统的精确性和实时性、保证激光扫描数据的可靠性，建立了基于双振镜的激光扫描系统。采用数据精简、去噪处理、坐标转换、距离值补偿等数据处理技术，对激光扫描系统的数据进行了误差分析和噪声分析，通过机场的实地测试，取得了飞机泊位过程中的激光扫描数据。结果表明，通过对激光扫描数据的处理，可以实现飞机的准确泊位，与飞机停止线的误差小于100mm。%In order to realize the real-time and accuracy of an aircraft parking system and ensure the reliability of laser scanning data , a laser scanning system based on dual galvanometer was established .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.
