چکیده

VIDET is a research project active at the University of Bologna and 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. In this paper we describe VIDET’s real-time stereo-vision system, implemented on a standard PC based system, and present recent experimental results. The stereo-matching algorithm exploits SIMD instructions to fulfill the timing constraints required to interact in real-time with the haptic interface and has proven to produce reliable depth maps.

Wearable Real-Time Stereo Vision for the Visually Impaired

Visually impaired find their navigation difficult as they often lack the needed information for bypassing obstacles and hazards. Electronic Travel Aids (ETAs) are devices that use sensor technology to assist and improve the blind user’s mobility in terms of safety and speed. Modern ETAs does not provide distance information directly and clearly. This paper proposes a method for determining dist...

RGB-D camera Based Navigation for the Visually Impaired

We present a wearable RGB-D camera based navigation system for the visually impaired. The navigation system is expected to enable the visually impaired to extend the range of their activities compared to that provided by conventional aid devices, such as white cane. Since this design is a successor version of a previous stereo camera based system to overcome a limitation of stereo vision based ...

visually impaired pedestrians

Sighted guidance is arguably the most efficient method for aiding visually impaired pedestrians in mobility. A sighted guide's verbal instructions compensate comprehensively for the insufficiency of visual input in navigation. Moreover, the companionship entails sharing of responsibilities and thus increases the blind traveller's sense of security during a journey. The disadvantages of the sigh...
