Embodiment 1
[0033] Such as figure 1 As shown, this embodiment provides a visual aid method for integrating a camera module and a light sensor, including the following steps:
[0034] a: The light sensor is used to detect the ambient light intensity data in real time, and when the detected ambient light intensity continues to be higher than the first preset value for a set period of time, the user is given the first visual aid;
[0035] b: When the detected ambient light intensity is continuously lower than the second preset value for a set period of time, the user is given a second visual aid;
[0036] c: In the second visual assistance process, when it is further detected that the ambient light intensity continues to change within a certain period of time, start the camera module to collect image data of the user's surrounding environment, and when based on the image data of the surrounding environment and When the ambient light intensity determines that there are passing vehicles, a th...
Embodiment 2
[0054] Such as Figure 5 As shown, the difference between this embodiment and the first embodiment is that the processing chip 11 is also connected with a GPS module.
[0055] This implementation can combine the camera module 41 to more accurately confirm the real-time road conditions and environmental facility changes, and can combine the speaker to navigate the user, which not only ensures the user's personal safety on the road, but also guides the user to find the way home. road, to avoid situations such as getting lost and not being able to return home.
[0056]In other embodiments of the present invention, the device further includes a clock chip, and the processing chip 11 can collect clock information and give a voice time report to the user according to the clock information, and determine whether it is day or night in combination with the clock information.
[0057] In other embodiments of the present invention, the device also includes a weather forecast module, whi...

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...
