AllTerra Deutschland GmbH is the Trimble Center of Competence for Northern and Eastern Germany, and represents Trimble´s Geospatial, Marine and GIS divisions in the region using their mobile mapping solutions as well as all sorts of Geospatial products for several years on various projects all around Germany.
One of the latest products that have revolutionized the mobile mapping data collection has been the Trimble MX2 due to its portability and versatility being able to be deployed on all sizes of on- and off-road vehicles, quad bikes and boats.
One of our customers was interested in checking the results and accuracy of such a system from a boat in order to analyze the bridge clearance areas for river transportation.
We performed this 5 Km long pilot project close to Halle (Germany) on the Saale river. We used the Trimble MX2 with a dual head side laser scanner option and a Ladybug camera for 360° panorama pictures. This system additionally contains a surveying grade differential GNSS receiver and and IMU so the scans and images are continuosly georeferenced.
Both side scanners collect 36.000 points/second and rotate 20 times/ second. The Ladybug panorama camera composed by 6 individual cameras (5 horizontal and 1 to the top) creates a 30 Mpx panorama picture each 5 m. We chose a boat “walking” speed of 6 Km/h which gave us scan sections each 5cm.
