Kinect+Quadrocopter

"Researchers at the Hybrid Systems Laboratory at UC Berkeley mounted a Kinect sensor atop their Ascending Technologies Pelican quadrotor UAV, mapping the copter’s surroundings so it can avoid obstacles while traveling along a predetermined, programmed path."

TreeMetrics - the solution in forestry survey

I want to introduce the TreeMetrics, because this company developed a new forestry survey method with terrestrial laserscanning systems. The aim of this technique can be summarized in one sentence: The exact volume calculation of trees provides better product recovery in the sawmill. In addition, this workflow offers a forest condition monitoring opportunity, which can reduce the time of ecological returns. You will find more information on this webpage:

GPS coordinates estimation and camera calibration from solar shadows

Today, I want to present a new research about GPS coordinates estimation. The geolocation calculation of the digital camera was accomplished by using the shadow trajectories. Video sequences were analyzed by this technique in downtown Washington DC and the camera calibration was feasible with the camera footage as well.
I think, this research offers a very useful method in the forensic science!You will find the full paper here: http://cil.cs.ucf.edu/pdf/Junejo_Foroosh_CVIU2010.pdf
