手持激光雷达扫描仪飞马在地形测绘中的运用

Application of Hand-held LiDAR Scanner Pegasus in Topographic Mapping

SLAM的全称为Simultaneous Localization And Mapping即“同时定位与地图构建”。最近几年由于机器人、无人机、自动驾驶、AI、VR和AR技术的发展,SLAM技术逐渐被人们熟知。SLAM技术是通过激光传感器感知周围的环境,并将不同时刻感知的环境进行匹配套合,从而反推本体在环境中的位置及运动轨迹。随着SLAM技术的设备及定位精度的提高,该技术逐渐在测绘行业中使用,迅速成为除RTK和全站仪采点成图之外的一种地形图成图手段。国外GeoSLAM等公司推出大量的产品,在该领域处于领先地位,为打破国外封锁,国内的飞马、数字绿土等公司也研发出相应的产品。该文主要通过具体的案例论述国产手持激光雷达扫描仪飞马SLAM 100在地形测绘中的运用,侧重于表述SLAM技术及SLAM100产品在运用中的优缺点。

The SLAM refers to"simultaneous localization and mapping".In recent years,due to the development of robot,UAV,autopilot,AI,VR and AR technology,SLAM technology is gradually known by people.SLAM technology is to perceive the surrounding environment through laser sensors,and match the perceived environment at different times,so as to deduce the position and motion trajectory of the body in the environment.With the improvement of equipment and positioning accuracy of SLAM technology,this technology is gradually used in the surveying and mapping industry,and quickly becomes a topographic mapping method in addition to RTK and total station point mapping.Foreign companies such as GeoSLAM have launched a large number of products and are in a leading position in this field.In order to break the foreign blockade,domestic companies such as Feima and Digital Green Earth have also developed corresponding products.This paper mainly discusses the application of domestic handheld LiDAR scanner Feima SLAM100 in topographic mapping through specific cases,with emphasis on the advantages and disadvantages of SLAM technology and SLAM100 products in the application.
