Blind person navigation system and navigation method based on mobile equipment

Abstract

The invention discloses a blind person navigation system and method based on mobile equipment, and the method comprises the following steps: carrying out the navigation path planning according to the current position information and destination position information of a user, and guiding the user to advance according to the navigation path through voice, acquiring an environment image, depth information and mobile equipment state information on the navigation path in real time, identifying marker information in the environment image, superposing the marker information with the navigation path to form a virtual blind sidewalk, mapping the size of a marker in the environment image to an actual size, and broadcasting information contained in the virtual blind sidewalk to a user through voice; continuously collecting environment images to update the virtual blind sidewalk, and updating the voice broadcast content. According to the invention, a three-dimensional environment scene is constructed for the user, the user is helped to quickly merge into the environment, the psychological sense of security can be given to the user, the detection range of the mobile equipment is expanded, and the navigation effect on the blind is ensured.

Description

technical field [0001] The invention belongs to the technical field of navigation for the blind, and in particular relates to a mobile device-based navigation system and a navigation method for the blind. Background technique [0002] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0003] Blind or visually impaired people are quite inconvenient in life (especially when traveling alone), and need to provide better travel methods and auxiliary methods to alleviate the inconvenience of their lives. Now it is common to use walking sticks to detect road conditions ahead when traveling for the blind. This method is used in The speed is slow during use, and it can only perceive the road conditions and environmental information within a range of about one meter around the human body. It has no clear understanding of long-distance road conditions and environmental information, and it is prone to u...

[0003] Blind or visually impaired people are quite inconvenient in life (especially when traveling alone), and they need to provide better travel methods and auxiliary methods to alleviate the inconvenience of their lives. Now it is common to use walking sticks to detect the road ahead when traveling for the blind. This method is used in The speed is slow during use, and it can only perceive the road conditions and environmental information within a range of about one meter around the human body. It does not have a clear understanding of long-distance road conditions and environmental information, which is prone to unexpected dangers. In addition, the current various navigation devices , such as guide canes, guide glasses, guide helmets, guide shoes, etc., are inconvenient to carry, complicated to use, and require supporting equipment. The navigation ability is limited, and it is difficult to meet the daily needs of the blind.
