Embodiment Construction
[0024] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.
[0025] like figure 1 As shown, a portable walking aid guide device includes:
[0026] Micro camera head: used to collect images;
[0027] Road condition detection module: specifically includes a blind road recognition module and an abnormality detection module, wherein the blind road recognition module judges whether the current blind road is a blind road according to the image collected by the micro camera; if the current image is a blind road, the abnormality detection module detects whether the blind road is abnormal. The road condition detection module transmits the processed road condition information to the main control module;

The invention discloses a portable walking aid blind guide device and a method on the basis of blind sidewalk line characteristic visual perception. The method includes steps of S01, acquiring images and recording acquired data in a two-dimensional array ImageBuffer[a][b]; S02, fetching a plurality of rows in the two-dimensional array ImageBuffer[a][b], and judging whether the acquired images are images of blind sidewalks or not; S03, judging whether the blind sidewalks are abnormal or not if the current images are the images of the blind sidewalks; S04, computing the offset of the center line of each current blind sidewalk relative to the center line of the corresponding image if the blind sidewalk is normal, and converting the offset of each blind sidewalk into a required blind sidewalk turning angle for a blind person; S05, performing corresponding voice prompt according to detection results of the steps S02, S03 and S04. The a and the b are positive integers. Whether the blind sidewalks are curved sidewalks or not and whether obstacles or pot holes are available on the blind sidewalks or not are judged in the step S03. The portable walking aid blind guide device and the method have the advantages that characteristics of the blind sidewalks can be quickly and accurately captured by the aid of active vision according to line characteristics of the blind sidewalks, road conditions of the blind sidewalks can be identified, and accordingly the blind person can be guided to efficiently and safely advance; the device can be manufactured to form blind guide spectacles convenient to wear after the device miniaturized.
Description
technical field [0001] The invention relates to a portable walking aid guiding device and method. Background technique [0002] According to the statistics of the World Health Organization, there are about 285 million people suffering from visual impairment in the world, of which 39 million are blind, and 90% of the visually impaired patients in the world live in developing countries. The development of blind guide devices and supporting municipal road construction is of great significance for improving the quality of life of blind people. However, due to the limitation of social development level, blind roads are often damaged or temporarily occupied. Moreover, the current feeding and cost of guide dogs is very high , Guide sticks cannot accurately detect potholes, breakages and road turns and intersections in blind roads, and guide vehicles are not suitable for carrying and cost high, and they cannot become economical and easy-to-use mobility aids for most blind people. ...
