摘要
三维激光扫描技术是近几年来发展起来的一项新兴技术,该仪器具有采集点云速度快、质量高、精度优良,非接触式的特点,本文分析了三维激光扫描仪外业采集数据作业流程与内业建模处理流程之后,将其利用在日照测量中。分析了系统误差与偶然误差的来源,并且提出了减小误差的方法,最后通过工程实例,比较了与全站仪实测精度以及工作效率,最后得出了三维激光扫描仪在日照测量应用中的可行性与适用性。
3D lasers canning technology is a new technology developed in recent years.The three-dimensional laser scanner has the advantages of fast acquisition speed and high quality. It has excellent precision and non-contact characteristics. After analyzing its data acquisition and processing flow, it is used in sunshine measurement. The source of system error and accidental error is analyzed, and the method to reduce the error is put forward. Finally, through an engineering example, the accuracy and efficiency of the total station are compared. Finally, the feasibility and applicability of the three-dimensional laser scanner in sunshine measurement are obtained.
