摘要
The ever-increasing speed of current general purpose processors, together with architectural enhancements such as multimedia-oriented instruction set extensions, allow for deploying standard PC-based systems in a number computationally intensive computer vision tasks. This paper describes the PC-bused real-time stereo vision sl system developed rr within the VIDET project, which is a research project aimed at the development of a mobility aid for the visually impaired. VIDET's approach consists in the conversion of depth data gathered through a stereo vision system into a 3D model perceivable by the user by means of a wire-actuated haptic interface. The developed stereo matching algorithm makes massive rise of recursion and multimedia instructions ro achieve the performance figures needed to sustain user's real-rime interaction with the 3D model through the haptic interface.
