Visual guide cane and navigation method based on visual guide cane

Abstract

The invention provides a visual guide cane and a navigation method based on the visual guide cane. The visual guide cane comprises a guide cane main body, an image acquisition device, an image processing device and a voice interaction device; the image acquisition device, the image processing device and the voice interaction device are sequentially communicatively connected; the image processing device is used for processing and storing information and controlling the voice interaction device; the image acquisition device is used for acquiring the scene depth image information; the image acquisition device transfers the acquired depth image information to the image processing device; the image processing device performs navigation prompt through the voice interaction device. The visual guide cane solves the problems of traditional guide canes which fail in fast and accurate positioning, short-distance three-dimensional obstacle avoidance, stereoscopic environment memory and the like, and is favorable for solving the problems of walking difficulty and movement safety of the blind.

Description

technical field [0001] The invention relates to the field of intelligent auxiliary equipment, in particular to a visual guide crutch and a navigation method based on the visual guide crutch.
