Problems solved by technology

[0003] The above-mentioned intelligent navigation system for the blind has certain functional defects, and most of them can only judge whether there are obstacles in the surrounding area from the perspective of the blind. Such navigation systems cannot make overall accurate judgments and route p

Embodiment Construction

[0021] specific implementation plan

[0022] Further illustrate the present invention below in conjunction with accompanying drawing.

[0023] Such as figure 1 , figure 2 As shown, a navigation device for the blind based on two-dimensional code recognition and precise positioning of the present invention includes a smart hat module, a camera module, a data processing module and an alarm module. The camera module is used for real-time collection of obstacle information on the road, such as moving pedestrians, stationary objects, etc., and transmits the image information to the data processing module. The data processing module is used to process signals and analyze planning. If there is an occupation behavior, an alarm signal will be triggered, and the signal will be sent to the alarm of the alarm module. The alarm will send out a warning sound. related sites. If there is a blind person passing by at this time, the image information from the smart cap is collected through ...

Abstract

The invention discloses a navigation device for the blind based on two-dimensional code recognition. Based on the principle of two-dimensional code recognition, the navigation device for the blind based on two-dimensional code recognition collects road images through a camera installed at a high place, converts the images into signals and sends the signals to a system, which receives and processesthe signals sent by the camera, gets directions and generates navigation information, thereby providing the walking blind with guidance. When a current road is occupied, the system will detect and trigger an alarm signal and transmit the alarm signal to an alarm of the alarm module. The alarm will sound a warning to remind occupants, which can reduce the occurrence of illegal road occupation to acertain extent.

Description

technical field [0001] The invention relates to a navigation device for the blind, in particular to a navigation device for the blind based on two-dimensional code identification. Background technique [0002] In order to provide guidance for the blind to avoid obstacles, people use the signals sent by the hand-held tools used by the blind to make the blind perceive the obstacles ahead; or in order to reduce the obstacles on the blind road for the blind, people remind passers-by to reduce the blind road by installing monitoring devices for the blind. occupancy behavior. For example: a real-time obstacle avoidance system for blind navigation (CN105342816A, substantive review) realizes positioning through GPS navigation module and handheld radar, and reminds module and communication module to transmit nearby obstacle information to blind people through microprocessor; a blind person Obstacle avoidance device and its prompting method for obstacle avoidance (CN105030494A, subst...
