Embodiment Construction
[0058] The specific implementation of the present invention will be described in detail below in conjunction with the drawings and preferred embodiments.
[0059] Such as figure 1 with 2 As shown, the present invention provides a safety device for autonomous travel of the visually impaired, including a controller, the controller and a video acquisition module, a voice input and output module, a positioning module, a blind guide module, a navigation module, and an image processing module Connected. The controller communicates with the remote control platform through the websocket protocol and the stomp sub-protocol, and is connected to the video capture module and the blind guide module through the wireless communication module. The remote control platform is used to display real-time path information and location information for the visually impaired.
[0060] The video capture module is used to collect video information on the blind track, and can be set as glasses with a camera t...

The invention belongs to the technical field of intelligent control. The invention discloses safety equipment for autonomous travel of visually impaired people. The safety equipment includes a controller, the controller is connected with a video acquisition module, a voice input and output module, a positioning module, a blind guiding module, a navigation module and an image processing module. Thevideo acquisition module is used for acquiring video information on the blind sidewalk; the image processing module is used for processing multiple pieces of video information, obtaining the trend ofthe blind sidewalk and obstacles on the blind sidewalk; the positioning module is used for acquiring position information of visually impaired people in real time; the navigation module is used for navigating according to the destination of the visually impaired person; wherein the voice input and output module is used for collecting voice input of visually impaired people, according to the walking path planned by the navigation module, the image processing module obtains the direction of the blind sidewalk and obstacles on the blind sidewalk and carries out voice broadcast, and the blind guiding module is used for assisting the visually impaired people in walking and giving an alarm to the obstacles.
Description
Technical field [0001] The present invention relates to the technical field of intelligent control, in particular to a safety device for autonomous travel of visually impaired persons and a method for judging the direction of the blind track and obstacles on it. Background technique [0002] In China, the visually impaired are a large vulnerable group. The survey shows that the number of visually disabled people in China has reached 13.5 million, of which more than 5.5 million are blind, accounting for 18% of the total number of blind people in the world. At the same time, there are more than 8 million people with low vision. The number of visually impaired people is huge, but there are still many problems that need to be solved urgently in the current situation of the safety of the visually impaired in our society. [0003] There are not many guide aids available at home and abroad, and most of them are in the stage of exploration and laboratory, and few are commercialized. In th...
