摘要
针对当前地形测绘过程中存的工作效率、测绘精度差等弊端,提出了基于三维激光扫描技术的地形测绘方法。首先对当前地形测绘的研究现状进行了分析,指出引起测绘精度差原因,然后分析了三维激光描述技术的工作原理,然后对三维激光扫描数据进行去噪,配对等处理,实现地形测绘,最后与通过传方法进行了仿真对比实验,结果表明,本文方法具有较高的地形测绘精度高,工作效率优,具有传统方法无可比拟的优势,在测绘领域具有较高的应用价值。
For the drawbacks such as low efficiency and accuracy of current topographic mapping,a method of topographic mapping based on 3 D laser scanning technology is proposed. Based on the analysis of current status of topographic mapping,pointing out the causes of low mapping precision. Then,analyzing the working principle of 3D laser description technology and denoising and matching the 3 D laser scanning data to realize topographic mapping. Finally,contrast simulations are carried out,the results show that the method in this paper has high precision,excellent working efficiency and comparable advantages to traditional method which has high application value in the field of topographic mapping.
