Abstract

The embodiment of the invention provides an intelligent tactile stick with blind sidewalk detection and positioning functions and a blind person guiding method. The intelligent tactile stick comprisesfour parts including a stick body, a camera, a processor and a voice output module, wherein the camera and the processor are installed on the stick body; the camera is used for collecting pictures, the processor is used for conducting blind sidewalk detection on the pictures to obtain a vision detection result, and the voice output module is used for broadcasting the detection result to remind auser of the specific position of a blind sidewalk. The blind person guiding method comprises the steps of obtaining the pictures taken by the camera; detecting and positioning the blind sidewalk in the pictures to obtain the vision detection result, wherein the detection result comprises the relative position of the blind sidewalk; broadcasting the detection result through the voice output moduleto remind the user of the specific position of the blind sidewalk. According to the embodiment, through the tactile stick, the pictures are collected for analysis processing, then the blind sidewalk in the pictures is detected and positioned to obtain relative position information of the blind sidewalk, the blind person is guided in quickly walking to the blind sidewalk, and the accuracy and convenience of positioning the blind sidewalk are improved.

Description

technical field [0001] The invention relates to the field of blind guide technology, in particular to an intelligent blind guide stick and a blind guide method with the function of blind path detection and positioning. Background technique [0002] According to the World Health Organization (WHO) estimate in 2017, there are about 1.3 billion visually impaired people in the world, of which about 36 million people suffer from blindness. Visually impaired people encounter many inconveniences in their lives, one of which is the inability to travel independently. In the 1930s, the guide stick came out. Since the blind guide stick can detect the surrounding environment, it expands the tactile range of the blind and becomes the main tool for many blind people to travel. At the same time, the blind cane has also become a symbol of the visually impaired, and it has a certain warning effect on the people around. [0003] In recent years, many foreign researchers have devoted themse...
