Turn Your Smartphone into a Versatile Centimeter-Level Surveying Tool: Point Cloud Scanning, AR, Coordinate Guidance, and More Turn your smartphone into a versatile centimeter-level surveying tool. By simply attaching the high-precision GPS device “LRTK” to a smartphone or tablet, users can perform centimeter-level positioning, 3D point cloud scanning, stable AR without positional drift, coordinate guidance, and many other functions, all with a single smartphone. When taking photos, LRTK records position and orientation with high accuracy, and the data can be managed and shared via the cloud. With CLAS support, positioning is also possible even outside network coverage. LRTK can generate orthophotos from point clouds and automatically create DXF and DWG drawings. LRTK is a next-generation positioning device that can be used across a wide range of fields, from civil engineering and construction to infrastructure management, helping improve efficiency on job sites.
