Abstract(in English) | For the visually impaired who need to negative the inside of an unfamiliar building, we developed a navigation system with an autonomy running unit and a speech synthesizer to guide from the present point to the destination. The system uses invisible codes, which is made by infrared reflective pigment, as landmarks to provide position data at each point on the wall in a corridor. A CCD camera and two ultrasonic sensors are used to input bar code data and to measure the distance between the unit and wall respectively. In experiments, we confirmed the autonomy running of the prototype system. The results showed that the system could reach the destination at an average speed of 1km/h within an error of 20cm from the wall within the detection range from 30 to 90cm. |
