Study Of Survey Technology Based On The Domestic Aoe Airborne Lidar

The investigation in this paper is based on the AOE-LiDAR airborne LiDAR system, produced by Academy of Opto-Electronics (AOE), Chinese Academy of Sciences. Based on AOE-a120 airborne LiDAR system, the investigation is to analyze factors impact on surveying, to design flight plan, to develop adapted flight management software.Main researches in this paper are as follow:(1) Based on studying correlation theory and analyzing to LiDAR's surveying flow, this article shows the importance and necessity of flight surveying technology research.(2) Based on the survey criterion of traditional aerial photogrammetry, this article discusses the airborne LiDAR flightline designing technology. These researches include collecting survey area information, designing ground sample distance, selecting design map, and calculating aerial survey technical parameters.(3) This paper presents a new method about survey parameters designing based on the constraint network. Compared with airborne photogrammetry devices, airborne LiDAR system's operation contains more surveying parameters controlling and tuning procedures, and internal relationships among survey parameters. This article will describe these relations by using constraint network and provide a method and corresponding toolkit to handle survey parameters setting in surveying practice.(4) Through analyzing to flight plan design theory and AOE airborne LiDAR system, develop adapted flight management software. SS-NAV flight management software is developed on Python and GTK+ environment platform, which is supported by cross-platform and easy to use. This software has such practical functions mentioned above: flightline design, parameters design, flight navigation, monitor etc.(5) At last, this paper introduces an experiment in Tianjin using AOE LiDAR system. This experiment can verify performance of each part and integration of each sub systems. Through the analysis of the point clouds and navigation data in experiment, it is proved that SS-NAV flight management software is reliable, and provided flight plan is reasonable.
