基于虚拟触觉的导盲手套的开发OACSTPCD

Objective Aiming to the limits of current guiding system,such as inaccuracy,insufficient safety and inconvenient travel for the blind population,to design a guiding glove based on virtual touch,so as to help the blind person solving their mobility problems.Methods The routing plan through combinations of the Beidou navigation module was projected.Visual recognition and time-of-flight technique were combined to identify road conditions,and the finger movement to generate virtual armrest for guidance was realized to construct virtual handrail and guide the blind.Results Ten common obstacles on blind roads were selected for visual identification,with an average recognition rate above 89%and a frame rate greater than 14.5 fps.The error of distance measurement was less than 5 cm.Conclusion The validation results show that the proposed system can meet the demands of road identification,distance measurement and tactile sense guide for destination,obstacles,signal lights and bus stop signs.
