Equipped with 3D laser scanners, GPS, IMU, and odometry on vehicles and trolleys, we collect 3D point cloud data while moving!
"Mobile 3D Measurement" involves equipping vehicles or trolleys with 3D laser scanners, GPS, IMU (Inertial Navigation System), odometry (distance measurement), etc., to acquire three-dimensional point cloud data while moving. The obtained point cloud data can be used for extracting tunnel cross-sections, measuring architectural clearances, and designing when adding auxiliary facilities. 【Features】 ◇ Inspection Speed 3 km/h to 80 km/h (the point cloud acquisition pitch in the direction of travel changes depending on the speed) ◇ Measurement possible in GPS-denied environments ◇ Highly reliable drawings (CAD conversion) ◇ Analysis, design, and various numerical simulations of three-dimensional data are possible ◇ By measuring before tunnel photography with the "Mobile Tunnel Imaging System," it is possible to obtain more reliable images. *For more details, please refer to the PDF document or feel free to contact us.
