Abstract

The present invention provides a real-time navigation method and device for the visually impaired, wherein the method includes: acquiring navigation data, wherein the navigation data includes: speed, direction, obstacle distance, obstacle size, and voice; performing adjustments to the voice Operation, wherein the adjustment operation includes at least one of the following: speed-oriented timbre adjustment, direction-oriented stereo adjustment, tone adjustment oriented to obstacle distance, and loudness adjustment oriented to obstacle size; perform the adjusted voice playback operation. The invention can provide navigation services to visually impaired people under the condition of close to zero delay. Compared with the existing navigation solutions, the present invention can provide high real-time performance, usability, accuracy and richness of information, and significantly improve the daily exercise experience of visually impaired people.

Description

technical field [0001] The invention relates to the field of computers, in particular to a real-time navigation method and device for visually impaired people. Background technique [0002] Visually impaired people are limited by their limited visual ability and usually rely on guide dogs, voice navigation or special tools. The actual use experience reduces navigation efficiency. Taking voice navigation as an example, it predicts the forward route by analyzing the user's environment, and then describes the forward route, direction and other information to the user through continuous voice prompts. However, limited by the user's comprehension ability, comprehension speed and other conditions, voice navigation may have misunderstandings, slow comprehension, inability to comprehend, etc., resulting in the user's inability to move forward normally. Contents of the invention [0003] The present invention aims to provide a real-time navigation method and device for visually i...
