Blind guiding robot based on hybrid sensing system

Abstract

The invention discloses a blind guiding robot based on a hybrid sensing system, which comprises a sensing unit, a control unit and a motion unit, and is characterized in that the sensing unit acquires the surrounding environment of the blind guiding robot and transmits the acquired sensing data of the surrounding environment to the control unit; the signal output end of the control unit is connected with the motion unit and sends an instruction to the motion unit; the motion unit drives the blind guiding robot to execute actions according to the received driving signal; the sensing unit comprises a visual sensing unit, a laser sensing unit and a sound sensing unit which are respectively connected with the signal input end of the control unit. According to the invention, various sensors are used for detecting the surrounding environment and making corresponding feedback, and the visual perception function effectively avoids obstacles and identifies a target object. The laser sensing function provides a correct path for the blind to move, and autonomous navigation is achieved. Sound source positioning and voice interaction are achieved through the sound sensing function, and blind guiding help is provided for the action of the visually impaired person.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to a blind-guiding robot based on a hybrid perception system. Background technique [0002] According to relevant data from the World Health Organization, as of 2010, there were about 8.248 million blind people in my country, and the number of new blind people is about 450,000 every year. According to this trend, the number of blind people in my country has already exceeded 10 million. Blindness and visual impairment are one of the serious social and public health problems in the world. More than 70% of human information is obtained through vision. In order to meet the needs of blind people, various guide devices have emerged . [0003] However, the current traditional blind guide equipment has the following problems: [0004] 1. Mainly rely on guide dogs and blind walks, but there are no auxiliary facilities such as blind walks in many places. At the same time, f...

Problems solved by technology

[0004] 1. Mainly rely on guide dogs and blind walks, but there are no auxiliary facilities such as blind walks in many places. At the same time, for the public in public places, although the acceptance of guide dogs is gradually increasing, there are still occasions where guide dogs are prohibited from entering , news of guide dogs being turned away is not uncommon

[0005] 2. In addition, most of the blind guide sticks developed now have no function or incomplete functions. At present, there are intelligent guid
