摘要
在传统的地下空间测量中,需要频繁地搬站、引点,存在测绘效率低、精度不高等问题.本文提出采用手持激光扫描仪获取地下空间信息的方法.区别于传统的全站仪测量方法,本文提出的方法结合了SLAM技术,采用手持激光扫描仪应用于地下停车场的测量,且不存在控制点引点误差等问题.通过选用一个地下停车场地进行测量,结果表明该方法能够在地下空间测量中快速获取三维坐标信息,显著提高测量效率,具有明显的成本优势.
Abstract
In traditional underground space surveying,it is necessary to frequently move stations and guide points,resulting in low survey-ing efficiency and low accuracy. This article proposes a method of using handheld laser scanners to obtain underground space information. Dif-ferent from traditional total station measurement methods,the method proposed in this article combines SLAM technology and uses handheld laser scanners for measurement in underground parking lots,without problems such as control point pointing errors. By selecting an under-ground parking lot for measurement,the results show that this method can quickly obtain three-dimensional coordinate information in under-ground space measurement,significantly improve measurement efficiency,and have significant cost advantages.
