Multifunctional intelligent blind guiding method, processor and multifunctional intelligent blind guiding device

Abstract

The invention discloses a multifunctional intelligent blind guiding method. The multifunctional intelligent blind guiding method comprises the following steps of receiving a voice command, and navigating; obtaining image data of an obstacle; carrying out recognition processing on digital image data, judging that threat is formed by the obstacle if the recognized obstacle is a static body, generating an ultrasonic ranging control command, and generating and outputting voice alarm information or vibration prompt information according to a ranging result if the ranging result is within a preset alarm range; and generating an ultrasonic ranging control command if the recognized obstacle is a dynamic body, carrying out threat anticipation calculation according to a ranging result, and generating and outputting voice alarm information or vibration prompt information if the obstacle is within a preset alarm range. The invention also discloses a multifunctional intelligent blind guiding device and a processor. According to the multifunctional intelligent blind guiding method, the multifunctional intelligent blind guiding device and the processor, which are disclosed by the invention, the blind guiding service can be more safely, conveniently and reliably provided for the blind, the blind is prevented from walking more distance and meeting the obstacle, and thus the blind can quickly and safely arrive at the destination.

Description

technical field [0001] The invention belongs to the technical field of information engineering and relates to an intelligent blind guiding technology, in particular to a multifunctional intelligent blind guiding method, a processor and a device thereof. Background technique [0002] At present, electronic blind guides are designed using the principles of echo ranging such as ultrasonic and infrared probes, or using image sensors and laser ranging methods to measure the distance of obstacles. These methods can detect the distance of obstacles very well. , but there are functional deficiencies in identifying obstacle categories and dynamic obstacles. [0003] In addition, a blind guide method or system using modern information technology, such as a blind guide device based on wireless communication, uses wireless communication and GPS positioning to help blind people navigate through manual services and reach their destination smoothly, but this device must require another per...

[0002] At present, electronic blind guides are designed using the principles of echo ranging such as ultrasonic and infrared probes, or using image sensors and laser ranging methods to measure the distance of obstacles. These methods can detect the distance of obstacles very well. , but there are functional deficiencies in identifying obstacle categories and dynamic obstacles

[0003] In addition, a blind guide method or system using modern information technology, such as a blind guide device based on wireless communication, uses wireless communication and GPS positioning to help blind people navigate through manual services and reach their destination smoothly, but this device must require another person's help. Help, not intelligent enough automation, and can not automatically identify obstacles; such as the visual guide method based on image processing, image sensor and orientation prompter, so that blind people can feel the shape information of obstacles and the direction of avoidance, but this method cannot make Blind people can effectively perceive obstacle distance information and obstacle categories, especially for the danger prediction of dynamic obstacles.
