1 Tutorial: Active 3D reconstruction of moving objects HIROSHI KAWASAKI, 1 RYUSUKE SAGAWA 2 and RYO FURUKAWA 3 Recently, 3D scanning devices which can capture moving objects are now widely available even in supermarket. Although such devices can retrieve depth information of the scene almost in realtime, accuracy, resolution and fps are significantly different each other. Indeed, 3D reconstruction algorithm for each device is also different and we still have no idea which one becomes most popular in the near future. In this tutorial, we introduce basic algorithm of current 3D scanning devices as well as new technology proposed recently Kagoshima University 2 National Institute of Advanced Industrial Science and Technology 3 Hiroshima City University TOF (time-of-flight) TOF 6),24) 30FPS 1 c 2011 Information Processing Society of Japan
