Description

technical field [0001] The invention relates to a computer-controlled blind guide technology. Background technique [0002] In the 21st century, with the rapid development of computer software, hardware technology, sensor technology, and intelligent control technology, the key technology of service robots has been significantly broken through, and service robots are becoming a new and fast-growing industry. [0003] According to international and domestic statistics, 20% of the disabled are visually disabled. [0004] The World Health Organization estimates that there are 40 million to 45 million blind people in the world, and low vision is three times that of blind people, about 140 million people. my country conducted a survey on visual disabilities in the 1980s, and the results showed that there were nearly 13 million visually disabled patients in my country, of whom about 5.5 million were blind. About 450,000 new blind people will appear in our country every year, that...
