| Abstract: | 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. |
