Navigation system and method for visual impaired person

Abstract

The embodiment of the invention provides a navigation system and method for a visual impaired person. The method comprises the steps that a current image collected by a visual sensor device is obtained; the current image and current path information are input into a navigation model, and attitude information output by the navigation model is obtained, wherein the navigation model is trained basedon sample images, sample path information, sample attitude information and sample identifications; based on the attitude information, audio navigation is provided for the visual impaired person. According to the method and system in the embodiment, by inputting the current image and the current path information into the navigation model, the attitude information is obtained to provide navigation to the visual impaired person, the navigation is detailed to guide the movement posture of the visual impaired person, it is ensured that the visual impaired person can receive detailed navigation information, even in an unfamiliar environment or a complicated environment, the visual impaired person can walk along a navigation path and successfully avoid obstacles, walking safety of the visual impaired person is ensured, and the application range of navigation for the visual impaired person is expanded.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of computer vision, and in particular to a navigation method and system for visually impaired persons. Background technique [0002] Visual impairment seriously affects the life of the visually impaired, especially restricting the outdoor activities of the visually impaired. How to ensure the safe and independent walking of visually impaired people has received extensive attention. [0003] With the development of navigation technology, the existing navigation method for visually impaired persons can provide low-cost, high-precision three-dimensional position through GPS (Global Positioning System, global positioning system), obtain the longitude and latitude coordinates of the geographical location of the blind person in real time, and The sensing device acquires the scene in front of you, performs real-time distance measurement and orientation judgment, and then obtains navigation in...
