Research to advance precision forestry
3D precision forestry is one of the main tasks in CoE-LaSR, which the partners have strongly focused on since 2007. During 2014-2016 all major players in forest sector in Finland have taken 3D precision forestry as one of their core development tasks....
Intensity calibration has led to Multispectral Laser Scanning
In laser scanning, intensity value is often recorded for each point – in addition to point cloud x,y,z information. The need for radiometric calibration of the laser scanning intensity stems from the possibility of using calibrated intensity as additional feature for...
CoE -LaSR -researcher appointed as Assistant Professor at Aalto University
One of our post doc researchers, Matti Vaaja, has been appointed Assistant Professor at Aalto University’s Department of Built Environment. (1.8.2017-31.7.2022.) This is a great success for the Centre of Excellence as our aim is to boost knowledge based growth...
World’s first miniature unmanned aerial vehicle (mini-UAV) based laser scanner
The first mini-UAV (FGI Sensei) including the laser scanner, intensity recording, spectrometer, thermal camera, and conventional digital camera has been developed at FGI in 2009 (see Jaakkola et al. 2010). Recently, the work on the mini-UAV has...
Single photon laser radar enables improved performance and miniaturization of radars
A first realization of a novel pulsed time-of-flight laser radar has been actualized by the CoE Oulu group. What makes the radar unique is that it is based on high speed (FWHM ~100ps) and high energy (~1nJ) optical transmitter pulses produced with a specific laser...
Improved Raman spectroscopy system: Many fields of application
The development of time-gated Raman spectrometer system by CoE Oulu group suggest CMOS SPAD based time-gating techniques could pave way to the better use of the high resolving power of Raman spectrometer techniques. Their potential fields of...
Multiplatform Mobile Laser Scanning (MLS)
Mobile laser scanning is an emerging technology capable of capturing three-dimensional data from surrounding objects. With state-of-the-art sensors, the achieved point clouds capture object details with good accuracy and precision. Many of the applications involve...
Operational forest inventory since 2008/2010
Today, the standwise forest inventory in Finland is based on airborne laser scanning, the research of which was started by Juha Hyyppä in 1997 in Finland (profiling waveform radar signal of forests studied in 1987-1996). As a result of co-operation of J. Hyyppä and...
National Laser Scanning Finland and Sweden since 2008
An increasing number of countries are applying airborne laser scanning (ALS) for national or statewide elevation modeling (e.g. The Netherlands, Switzerland, Finland, Sweden, Austria, Germany, US). In Finland, the technology was transferred from research done by...
