Vision aid method and vision aid device integrating camera module and optical sensor

Abstract

The invention provides a vision aid method and a vision aid device integrating a camera module and an optical sensor. The device comprises a processing chip, an optical sensor, a camera module and an indication module. When the optical sensor detects that the ambient light brightness is lower than a preset value, the indication module is opened and flickers for reminding. When the light brightness reaches over the preset value and a set time is up, the indication module is closed, and equipment actively opens the camera module to shoot the road condition. When the processing chip judges light intensity mutation as hardware facility change through image comparison, a lamp of the indication module is opened to remind a user of the position. The processing chip can also judge the position of a coming vehicle and calculate the approximate distance, and can remind a user of the dodge direction through vibration and voice according to an image captured by the camera module to enable the user to avoid the coming vehicle. Users can be reminded in real time, indication and early warning can be performed on the surrounding environment, and a guarantee is provided for the personal safety of users.

Description

technical field [0001] The invention belongs to a visual aid device, in particular to a visual aid method and device integrating a camera module and a light sensor. Background technique [0002] As we all know, eye disease has always been one of the main problems in the field of health. According to international and domestic statistics, one fifth of the disabled are visually disabled. There are about 45 million blind people in the world, and the number of low-vision people is about 100 million. 3 times of that, about 140 million. 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. [0003] The main information of human beings is obtained through vision, so visual disability is one of the most serious and painful disabilities among disabled people. At home and abroad, ultrasonic or infrared probes are generally used to find...

AI Technical Summary

Problems solved by technology

At the same time, in order to enable the visually impaired to better experience the innovations brought about by technology, products for the visually impaired are gradually increasing. Devices such as readers for the blind and positioning devices for the blind are emerging in an endless stream. Vehicle reminders and other equipment are still blank, and blind people still have great safety risks when going out alone
