Akhka: The first backpack high-end MLS presents unique mobility and ease of use in rugged terrain
A whole new approach for mobile laser scanning (MLS) was innovated and built to meet the challenges of mobility in marshlands and rugged terrains, but suitable also for narrow city passages and indoors. AKHKA system was designed to be operable by one person as a backpack MLS solution. The backpack platform is ideal to provide the required mobility and yet maintain the high performance 3D surveying capacity in such environments. In AKHKA the scanner head is mounted directly under the IMU unit to allow robustness and easy alignment.

ROAMER Mobile laser scanning system: A Unique high-speed scanner with an adjustable angle
The ROAMER mobile laser scanning system has been developed at FGI. It can be seen on top of a vehicle in its up-to-date configuration in the image (left). ROAMER is a high-end surveying device for producing accurate, dense, and precise point clouds for three-dimensional mapping for the detection, localization, modeling, analysis, and monitoring of anthropogenic and natural phenomena and processes. What is unique in the ROAMER construct are the high-speed scanner and possibility to adjust the scanning angle for application. The system is also easy to operate in terms of data recording facilities and mountability, which is shown by numerous study cases. ROAMER provides microscale 3D data at 20 mm absolute accuracy level at point densities up to 10 000/m2 for mapping of large areas effectively. ROAMER data contains high detail 3D points for mapping and modeling of urban area, roads, forests and parks, terrain topography, and change detection.

New research areas in the field of Laser Scanning (LS)
We have been active in initiating several new research areas in the field of laser scanning, such as individual tree inventory (Hyyppä and Inkinen, 1999), forest change detection (Hyyppä, et al. 2003, Yu et al. 2004), and densification of LS point clouds with photogrammetry (Savolainen at al. 2004). We have developed techniques for ALS intensity calibration since 2002 (e.g. Ahokas et al. 2006), active hyperspectral lidar since 2004 (Kaasalainen et al. 2007), mini-UAV-based LS research (Jaakkola et al. 2010), and the first whole-process LS from hardware to virtual reality in built environment in 3D game engine (Zhu et al. 2011).
