Title:
SMART CANE FOR BLIND PEOPLE BASED ON MOBILE WEARABLE COMPUTING AND FAST DEEP NEURAL NETWORK
Document Type and Number:
WIPO Patent Application WO/2022/151560
Kind Code:
A1
Abstract:
A smart cane for blind people based on mobile wearable computing, belonging to the field of electronic information. The smart cane for blind people is an assistive apparatus for blind people that is based on wearable computing technology. The apparatus itself has the functions of illumination, sound production, light emission and calling for help, and can control, by means of buttons, the enabling or disabling of functions on mobile smart devices (2, 3, 4, 5) that have been connected to the apparatus. The functions of the mobile smart devices (2, 3, 4, 5) comprise: the function of obstacle detection by using threshold value segmentation, RANSAC and a region growing algorithm; the function of broadcasting current time and position information via voice; and the function of traffic light detection. The present smart cane for blind people has the characteristic of single-finger operation, is automatically connected to the mobile smart devices (2, 3, 4, 5), and efficiently communicates with same; a supporting application has the functions of voice broadcasting of information, obstacle detection and traffic light detection; and a means of vibration is used for providing quick feedback to blind people, thereby enhancing the usage experience of the smart cane for blind people.
