Description
technical field [0001] The invention relates to the field of travel aids, in particular to a multifunctional navigation device. Background technique [0002] Blind people are a special group. They have lost their visual function due to congenital or acquired reasons, and their daily life, especially travel, is greatly restricted. The World Health Organization estimates that there are 40 million to 45 million blind people in the world, and nearly 13 million visually disabled patients in my country, including about 5.5 million blind people and 7.5 million low-vision patients. In real life, most blind people use ordinary bamboo, wooden sticks or ordinary blind sticks to assist walking. This kind of blind stick is just an ordinary long pole. Dangerous obstacles in the air can only be limited to the reach of the blind stick. Even though ordinary blind sticks use night vision luminous paint to improve passive recognition capabilities, blind people cannot actively know whether the...
