A Vision-based Gesture Recognition, Virtual Play

Virtual reality is the newest man -machine interactive technology in the 1990's. It is an advanced man-machine interactive technology which can emulate action of man validly ,such as action of hearing and speaking. It is integration of many technology such as artificial intelligence,computer graphics and man-machine interface .Computer-vision also is an advanced technology , It was used intensively in the fields of intelligent navigation , industry detection , medical image processing and other important fields. But in the technology of interactiving of virtual reality and computer-vision , the man-machine interactive by noncontacting become more and more broadly in the technology of 3D interactive. Although many researchers have done lots of working that the 3D object are made up according to computer-vision images ,but the work still can't perfectly success to be done. The novel work of this thesis can be done as follows, at first ,we add capture system of computer-vision in the virtual reality system which only has one kind of input through data -glove. Secondly, image- information is transferred to virtual hand that is in the virtual environment, so virtual hand success to track specific target through computer-vision .Finally, we success to play virtual piano by virtual hand .We must emphasis that image information is include the informations of two dimensional image coordinates and distance . We success to make virtual hand track specific target through computer-vision.. This work is important to the advanced technology of virtual hand tracking specific target through computer-vision which is valuable to the application in many fields.
