The LS600 is a handheld SLAM 3D laser scanner from ComNav Technology, marketed under the SinoGNSS brand. It fuses a multi-line LiDAR sensor with a survey-grade GNSS-RTK receiver, an inertial measurement unit, and dual 48-megapixel panoramic cameras in a single 1.9 kg aluminium body. The defining engineering feature is the tightly coupled GNSS-SLAM algorithm: outdoors, where RTK is fixed, the scanner produces absolutely georeferenced point clouds in real time without loop closures — the GNSS position constrains the SLAM drift to centimetre level as the operator walks. Indoors or in GNSS-denied environments (tunnels, basements, mines), the system falls back to camera-assisted visual-SLAM, with the option to introduce ground control points during post-processing for coordinate transformation.

Three scan modes for different project needs

Mode selection trades point density against range, letting a single instrument cover interior room scanning and open-terrain topographic mapping without swapping hardware.

SpectraColor and the dual-camera system

Two 48-megapixel cameras, each with a 190° circular fisheye field of view, capture overlapping panoramic imagery as the operator walks. ComNav's SpectraColor pipeline maps RGB values onto the LiDAR point cloud at sub-centimetre layer resolution, producing true-to-life colourised 3D data. Because the cameras are rigidly mounted and factory-calibrated to the LiDAR frame, the colour mapping is geometrically registered without the parallax errors that affect add-on camera kits requiring post-scan alignment. Images are stored as standard .jpg files alongside the .las point cloud for downstream processing in ComNav's RealEditor PC software or third-party platforms.

Field workflow and data handling

The LS600 is operated via the ScanMaster Android app over Wi-Fi or Bluetooth, with real-time point cloud preview — dubbed Flash Point Cloud Technology — displaying the scan as it builds, so the operator can verify coverage and data quality before leaving the site. Two removable 49.34 Wh Li-ion battery sticks provide approximately 1.5 hours of continuous scanning each, and a 30-minute fast-charge cycle means a two-stick rotation can sustain a full field day. The 512 GB internal SSD is expandable and connects to a PC via USB-C 3.2 Gen 2 at 400 MB/s for rapid data offload.
