Embodiment Construction

[0020] Below in conjunction with specific embodiment, further illustrate the present invention. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

[0021] The invention relates to a blind-guiding robot based on machine vision. The blind-guiding robot includes a car body, and a camera is installed on the head of the car body. When working, the camera collects images, and then processes the images by a central processing module in the car body, so that The guide robot recognizes common objects on the road such as traffic lights, guide lines and obstacles, and then informs th...

Abstract

The invention relates to a blind-guidance robot based on machine vision. The robot provided by the invention comprises a vehicle body, wherein a base is arranged below the vehicle body; a CCD (charge-coupled device) camera head is mounted at the head part of the vehicle body; a guide stick is mounted at the tail part of the vehicle body; a central processing module, an information sensing module, a voice module and a power supply module are arranged in the vehicle body; and a motion control module and an electrical transmission device are arranged in the crawler type base. The blind-guidance robot firstly uses the CCD camera head for collecting an image, then the image is processed by the central processing module arranged in the vehicle body, common objects such as traffic lights, blind-guidance lines, obstacles and the like on roads can be identified through the image processing and identifying method, then the blind-guidance robot can notify an operator of the result though the voice module, and the operator can control the blind-guidance robot through the decision-making method and the arbitration. The blind-guidance robot can automatically identify blind-guidance roads on sidewalks, feed back different road condition information in real time and guide the direction.

Description

technical field [0001] The invention relates to the technical field of machine vision and electromechanical control, in particular to a blind-guiding robot based on machine vision. Background technique [0002] The visually impaired friends have been living in a dark world for a long time, unable to experience the colorful world through vision, and must rely on touch, smell, and hearing to perceive the living space. Without the help of visual images, their travel safety and daily life are hundreds of times more dangerous than ordinary people. Being in an uncertain environment for a long time makes the visually impaired generally lack a sense of security, and the increasing dependence in life has made many visually impaired people lose confidence in life and have doubts. Therefore, based on the particularly strong safety requirements of the visually impaired, it is necessary to design a device that uses machine vision to make up for physiological deficiencies and ensure the ...
