The Dynascan 3D mobile mapping system from Measurement Devices, a subsidiary of Renishaw, can be mounted on vehicles and vessels and is designed to capture the LiDAR data at speeds of up to 43 mph.

The system’s built-in real-time kinematic (RTK) differential GPS system employs GNSS carrier-phase differential techniques to provide centimeter-level, 3D positioning.

The computed correction signals are then transmitted to the mobile GNSS receivers on the Dynascan over an ultra-high-frequency radio link. A high-grade inertial navigation system consisting of gyroscopes and accelerometers is also used to compensate for the motion, pitch and roll of the vehicle.

The resulting geo-referenced point-cloud data can be integrated with other static laser scanning data, survey data and photogrammetry to produce a 3D survey of a site, set or complete landscape.

The Dynascan system’s 360-degreee laser is capable of scanning up to 72,000 points a second with a range of up to 250 meters.
