摘要
公路工程的前期测量是测绘工作的重要组成部分。为提高测量精度和成图速度,工作者们使用过很多方法,包括全野外测量、传统航空摄影测量等,但这些方法均不能达到精度和速度的有效提升。论文探讨了新型的点云数据处理技术,用于地形图的生产,不仅提高了在山地、丘陵等地形中的测量精度,而且有效地降低了人力和时间的耗费量。
Prophase measurement of highway engineering is an important part of surveying and mapping work. In order to improve the measuring accuracy and mapping speed, many methods have been used, including field measurement and traditional aerial photogrammetry,but these methods can not achieve the effective improvement of accuracy and speed. In this paper, a new point cloud data processing technique is discussed, which is used in the production of topographic maps. It not only improves the surveying accuracy in mountainous and hilly terrain, but also effectively reduces the manpower and time consumption.
