New research areas in the field of Laser Scanning

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).
