Navigation device for blind and amblyopia group

Abstract

The invention discloses a navigation device for the blind and an amblyopia group. The navigation device comprises a server, a cane, a backpack and an RFID active tag. A first battery, a first controlmodule, a first wireless communication module, a first gyroscope, an RFID identifier, a first speaker, a binocular camera, an ultrasonic detector, an illumination lamp, a light sensor, a physical feedback module and a first microphone. A second control module, a second microphone, a GPS module, a second battery, a second wireless communication module, a third wireless communication module, a second gyroscope, a second speaker, a memory, a wired charger and a warning light are arranged in the backpack. Indoor navigation and outdoor navigation can be performed to monitor the environment in the navigation process, not only obstacle warning can be performed, but also the road information can be predicted to a user in advance. The exploration time of the user is reduced, the load on the hands of the user is alleviated, and the device is suitable for the blind and the amblyopia group.
