Resumo: | ||||||||
The need to perform spatial manipulations (like selection,
translation, rotation, and scaling) of virtual 3D objects
is common to many types of software applications, including
computer-aided design (CAD), computer-aided
modeling (CAM) and scientific and engineering visualization
applications. In this work, a prototype application for
manipulation of 3D virtual objects using free-hand 3D
movements of bare (that is, unmarked, uninstrumented)
hands, as well as using one-handed and two-handed
manipulation gestures, is demonstrated. The user moves his
hands in the work volume situated immediately above the
desktop, and the system effectively integrates both
hands (their centroids) into the virtual environment
corresponding to this work volume. The hands are being
detected and their posture recognized using the Viola-Jones
detection method, and the hand posture recognition
thus obtained is then used for switching between
manipulation modes. Full 3D tracking of up to two hands is
obtained by a combination of 2D flocksof-KLT-features
tracking and 3D reconstruction based on stereo riangulation.
