3D fingertip location estimation with a simple hand pose model and the depth information of a TOF camera

초록

The time of flight (TOF) camera is important equipment through which depth information for a 3D object can be obtained. 3D location detection using the depth information obtained with a TOF camera is accurate when the object of interest is large but yields numerous errors when the object in the image is small, as in the case of fingertips. The present study therefore proposes an algorithm whereby the locations of the hands can be found through depth information instead of fingertip information and, through that location information and geometric transformation of a simple hand pose model, 3D fingertip locations can be estimated.
