Indoor blind person navigation robot

Abstract

The invention discloses an indoor blind person navigation robot. The indoor blind person navigation robot comprises a navigation robot and a wearable mobile terminal. The navigation robot comprises a camera module, a walking module, a central control unit, a man-machine interaction module, a reminding module and a wireless communication module. The wearable mobile terminal comprises a voice module, an acceleration sensor and a wireless communication module. The navigation robot and the wearable mobile terminal are in communication through the wireless communication modules, the camera module acquires a three-dimensional environmental map, the three-dimensional environmental map and an indoor three-dimensional scene map are matched to acquire a current position, it is achieved that the robot detects and avoids obstacles and monitors the position of a blind user, the motion state of the walking module is adjusted to not deviate from a navigation path, a destination can be obtained through the voice module or the man-machine interaction module for path planning, and the blind user is reminded to change advancing directions and avoid the obstacles in real time. The indoor blind person navigation robot has the advantages of being convenient to use, high in positioning precision, high in obstacle avoiding capacity, wide in application prospect and the like.

Description

technical field [0001] The invention relates to the fields of automation and robots, in particular to the field of blind navigation. Background technique [0002] The World Health Organization estimates that there are 40 million to 45 million blind people in the world. Low vision is three times that of blind people, about 140 million people. In daily life, blind people have many inconveniences compared with ordinary people, especially the travel of blind people has been greatly affected. Although there are certain infrastructures for the blind to travel, such as blind roads, for the blind, it is inevitable to encounter obstacles when walking. Usually blind people rely on the sound of crutches to make judgments, but it is very difficult for blind people, especially in noisy environments, and blind people tend to get lost when performing large-scale activities, which limits the activities of blind people. Therefore, there is a need for a corresponding service-type navigation ...
