Blind road and obstacle identification system and method

Abstract

The invention provides a blind road and obstacle identification system and method. The blind road and obstacle identification system comprise a system master switch and the like, a walking stick handle is made of hollow plastic, the system master switch is inlaid in the left front end of the walking stick handle, a detection function shifting switch is arranged at the top end of the walking stick handle, a promoting function shifting switch is inlaid in the middle lower end of the walking stick handle, and a voice prompt module and a vibration prompt module are both disposed inside the walking stick handle; a walking stick body is made of hollow plastic, and a power module, an MCU (micro control unit) module, an obstacle detection module and a blind rod detection module are arranged sequentially from top to bottom; the system master switch is electrically connected with the power module; the detection function shifting switch and the prompt function shifting switch are both electrically connected with the MCU module; the voice prompt module, the vibration prompt module, the obstacle detection module and the blind road detection module are all electrically connected with the MCU module. The blind road and obstacle identification system is small in size, high in detection sensitivity, high in detection sensitivity, good in real-time performance and capable of meeting the requirement on market miniaturization.

Description

technical field [0001] The present invention relates to an identification system and an identification method, in particular to an identification system and an identification method for blind roads and obstacles. Background technique [0002] my country is one of the three high-incidence areas of blind people in the world, and there are about 12 million blind people, accounting for 18% of the total number of blind people in the world. About 450,000 new blind people are added every year. By 2020, the total number of blind people is expected to reach 20 million. Due to visual impairment, blind people have encountered great troubles when going out. For this reason, many countries have specially set up special-purpose blind roads that blind people are easy to identify on roads where blind people walk more. Blind roads are generally paved with two types of bricks, one is strip-shaped guiding bricks, which guide blind people to move forward with confidence, which is called walkin...

Problems solved by technology

There are few crutches specially used for blind road detection. Chen Wei, Xu Mai and Wang Zulin invented an image recognition-based intelligent blind guide stick (see Chinese Patent Publication No. CN103637900A), which can realize blind road recognition and bus information recognition. However, the crutch has a large volume, complex system, and poor real-time performance, which is not conducive to popularization and use.
