Abstract

The invention discloses an intelligent navigation system for the blind and a navigation method. The system includes a portable navigator that carries out double-directional communication through a data radio station and a remote assistance platform. The portable navigator takes an FPGA development board as a core and a microwave sensor, a camera, an infrared ultrasonic sensor, the data radio station, GPS, an earphone and a keyboard for the blind are connected on the FPGA development board. When indicating road information to the blind, the FPGA development board processes obtained moving object information, image information and barrier information, conducting audio prompt for the blind through the earphone; when a route planning for the blind is carried out, the keyboard for the blind inputs traveling information to the FPGA development board and transmits the information to the remote assistance platform through the data radio station; and after determining the traveling proposal, the remote assistance platform transmits the information to the FPGA developing board through the data radio station, and carrying out audio prompt for the blind through the earphone. The intelligent navigation system for the blind solves the problems of not being convenient, safe and real-time in the existing guidance ways.

Description

technical field [0001] The invention belongs to the technical field of embedded system development and multi-sensor information processing, relates to a navigation system, in particular to an intelligent navigation system for the blind, and also relates to a navigation method using the system. Background technique [0002] There are 16.91 million blind and vulnerable groups in my country. When they travel, they will face various complex and changing traffic environments. The increasing number of motor vehicles and various obstacles on the road will threaten the travel of blind people. The travel mode of the blind can generally be divided into two categories, one is walking on foot, and the help needed in this travel mode is mainly to guide and avoid obstacles; the other is the long-distance travel by car. , The help you need is mainly to guide how to get on the bus, how to transfer, and give tips before getting off the bus. The existing guide tools for the blind are mainly ...
