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