摘要
车载移动立体测量系统可以用于快速、准确的高精度数据采集和三维建模。针对车载移动立体测量检校问题,设计了一套高精度的车载移动立体测量系统检校方法,建立了检校的数学模型,并进行了试验,分析了检校前后车载移动立体测量系统的测量精度差异。实验证明,本文研究的车载移动立体测量系统检校方法能有效地提高系统测量精度。
Vehicle-borne mobile 3D measurement system can be used for rapid and accurate data acquisition and three-dimensional modeling.In order to solve the calibration problem of vehicle-borne mobile 3D measurement,a high-precision vehicle-borne mobile 3D measurement system calibration method is designed and a mathematical model of overall calibration is built.Then,experiments are carried out and analysis of the measurement accuracy of the 3D measurement system before and after calibration is made.Test proves that the calibration method of vehicle-borne mobile 3D measurement system proposed in this paper can effectively improve the precision of the system.
