Bernabei D., Ganovelli F., Di Benedetto M., Dellepiane M., Scopigno R. A low-cost time-critical obstacle avoidance system for the visually impaired. In: IPIN 2011 - International Conference on Indoor Positioning and Indoor Navigation (Guimara, Portugal, 21-23 September 2011).
We present a low cost system for unassisted mobility of blind people built with off-the-shelf technology. Our system takes as input the depth maps produced by the Kinectic device coupled with the data from its accelerometer to provide a registered point based 3D representation of the scene in front of the user. We developed a time-critical framework to analyze the scene and classify the ground and still or moving obstacles and provide the user with a constant and reliable feedback.
