摘　　要：以宁波市测绘设计研究院的车载激光扫描与全景成像城市测量系统为例,在速度、激光入射角和GPS信号失锁等不同外部条件影响下,获取了大量实验数据。综合分析评价了车载移动测量系统的数学精度变化情况,为移动测量系统在各种城市测量环境中的适用性提供参考依据,以期扩大该技术在测绘领域的应用。On the basis of mass data from the vehicle-borne Li DAR system and the urban panoramic imaging measurement system, this paper made a comprehensive analysis to assess the mathematical precision of the vehicleborne mobile measurement system with various external influence factors, such as speed, laser incident angle and the loss-of-lock on GPS signal. This paper provided references to the applicability of the vehicle-borne mobile measurement system in urban area.
