Riegl lidar sensors and systems unveiled

Riegl gave an overview and demos of its lidar sensors and systems product range at Intergeo, with recent developments and latest product unveilings:

The VQ-1560i Dual Lidar Channel Airborne Laser Scanning System, designed for airborne surveying missions from ultra-wide area, high-altitude mapping to mapping of complex urban environments and city modeling. This is the latest advancement of the ultra wide-area, high altitude airborne mapping system LMS-Q1560 that is in current operation at institutions, service providers, and research organizations worldwide.

The VQ-1560i has a fully integrated high-performance Applanix IMU and GNSS receiver suited for a variety of airborne surveying missions from ultra-wide area, high altitude mapping to mapping of complex urban environments and city modeling.

Two linear lidar channels, each enabling the recognition of several targets per laser pulse, provide an  laser pulse repetition rate of up to 2 MHz and deliver up to 1.33 million measurements per second on the ground. The system allows data acquisition at a  range of point densities from 2 pts/sqm up to more than 60 pts/sqm at operating flight altitudes of up to 15,500 ft AGL.

The VQ-1560i provides online data processing as well as smart and full waveform recording similarly and enables multiple-time-around (MTA) processing of up to 20 pulses in the air simultaneously. The optional system configuration consists of a fully integrated, easy accessible Phase One medium format camera and is prepared for the integration of a secondary camera such as monochrome or infrared.

The miniVUX-1UAV Lidar Sensor, an entry-level addition to Riegl’s UAV-based lidar sensor portfolio. The miniVUX-1UAV is a very compact miniaturized 360 degrees field of view lidar sensor weighing 1.6 kilograms and especially developed for the implementation of emerging survey solutions by small UAS/UAV/RPAS. The new sensor offers multi-target capability and accuracy using echo digitization and online waveform processing for data acquisition.

The sensor is capable of 100,000 measurements per second and offers an operating altitude of 100+ meters. Its small size and  low weight make it well suited for mounting under limited weight and space conditions, allowing UAV-based acquisition of survey-grade measurement data from agriculture & forestry, archaeology and cultural heritage documentation, to glacier and snowfield mapping and landslide monitoring.

The BDF-1 Bathymetric Depth Finder, fully integrated to Riegl’s Bathycopter and designed for generating profiles of inland water bodies. The BDF-1 is a compact and lightweight bathymetric depth finder optimized for UAV-borne operation.  The topo-bathymetric depth finder comprises tilt compensation, an IMU/GNSS unit with antenna, a control unit, a data storage unit, and can be equipped with up to two external digital cameras. Riegl’s new hydrographic full waveform processing delivers highly accurate, reliable and informative data; pre-detection averaging allows essential performance improvement at adverse conditions.
