摘要
针对城市三维模型质量检验难度大、耗时长、效率低等问题,本文制定了一套应用移动测量系统进行三维模型成果质量检验的流程,分别采用LiBackpack DGC50背包式、HiScan车载式移动测量设备对三维模型成果进行质量检验,并与传统检验方法在外业数据采集、内业数据处理及数学精度等方面进行重点比较、分析,统计出平面精度检测中误差最大为24.9 cm,高度精度检测中误差最大为19.3 cm。对三维模型成果的各质量元素检查后进行评分,计算成果质量得分,判定质量等级,结果表明:利用移动测量设备进行城市三维模型成果质量检验,方法可行、可靠。本研究结果为移动测量设备对三维模型成果进行质量检验的可行性提供理论依据。
A set of procedures for the quality inspection of three-dimension(3D)results is developed by using mobile measurement systems to solve the problems of difficulties,time-consuming and low efficiency in the quality inspection of urban 3D models.The quality inspection is carried out by using LiBackpack DGC50 and Hiscan vehicle-mounted mobile measuring equipment respectively.According to the comparison and analysis of traditional inspection methods in field data collection,indoor data processing and mathematical accuracy,the maximum error in plane accuracy detection is 24.9 cm and the maximum error in height accuracy detection is 19.3 cm.The scores are calculated after checking the quality elements of 3D model results to determine the quality level.The results show that it is feasible to use mobile measuring equipment to check the quality of urban 3D model.The results can provide a theoretical basis for the feasibility of quality inspection of 3D model results by mobile measuring equipment.
