The eSurvey eHLS1 is the first portable handheld LiDAR scanner independently designed and manufactured by eSurvey. It's lightweight, flexible, and easy to operate. Adopting the new high-precision SLAM technology, the eSurvey eHLS1 can create 3D reconstruction of the environment indoors and outdoors without depending on GNSS positioning, and help professionals achieve centimeter-level point cloud data while walking. With self-researched eSCAN processing software, effective post-process of point cloud data and multiple applications of point cloud becomes possible.
