【摘要】机载双频激光雷达探测技术利用双波长激光实现海陆一体化测绘,从1969年至今,国际上已经形成了成熟的商业产品,应用于海洋、海岸带和岛礁的探测。中国科学院上海光学精密机械研究所从1998年开始,先后研发了三代机载双频激光雷达,完成了从原理样机阶段到产品样机阶段的转化。最新的Mapper5000系统在南海完成了11个架次的机载飞行试验,获得南海岛礁的三维地形数据,最大实测深度达到51m,最浅水深达到0.25m,测深精度为0.23m,水平位置精度为0.26m,海洋测点密度为1.1m×1.1m,陆地测点密度为0.25m×0.25m。更多还原

【Abstract】 Airborne dual-frequency LiDAR detection technology collects simultaneous land and water-depth measurements using dual-wavelength laser.Since 1969,some commercial products have been formed for ocean,coastal zone and reef detection.Since 1998,Shanghai Institute of Optics and Fine Mechanics has successively developed three generations of airborne dual-frequency LiDAR,transforming from principle sample machines to product sample machines.The 11 flights tests of latest Mapper5000 system have been completed in the area of the South China Sea.Topographic and hydrographic data of islands and reefs have been collected.The measured hydrographic range is from 0.25 mto 51 m.The measured hydrographic vertical and horizontal accuracy are 0.23 m and 0.26 m,respectively.The measured hydrographic and topographic spatial density are 1.1 m×1.1 m and 0.25 m×0.25 m,respectively.更多还原
