车载移动测量系统大比例尺测图精度控制研究

Accuracy Control Research of Large-scale Topographic Map Revision Based on Vehicle-borne Mobile Surveying System

车载移动测量系统作为一种先进的测绘技术,已广泛应用于大比例尺测图项目中。SSW车载激光建模测量系统能够快速、高效、精确地完成大比例尺测图数据采集、处理等工作。不同比例尺对精度的要求不一样,而本文选择若干试验区,探讨不同的数据采集与处理方式对精度的影响,然后制订相应的精度控制方案,提高数据的精度,满足1∶1 000比例尺测图要求。

As an advanced technology of surveying and mapping,vehicle-borne mobile measurement system has been widely used in large scale mapping projects.SSW vehicle-borne laser modeling measurement system can be fast,efficient and accurate completion of large-scale mapping data acquisition,processing,etc. Different scale is different to the requirement of accuracy. This paper mainly discusses the influence of accuracy using different methods of data acquisition and processing,and then formulate corresponding precision control scheme to improve the accuracy of the data,which satisfy the 1: 1 000 scale mapping requirements.
