Problems solved by technology

[0003] At present, most of the blind people travel by relying on blind sticks to perceive blind roads and some obstacles on the road, and some rely on blind dogs to assist them in walking. Because the training of blind dogs takes a long time, and the number is limited and expensive, most blind people cannot pass. Blind dogs get help, and it's often unsafe to travel alone with a cane
[0004] However, some devices for the blind in the market, such as guide glasses, can indeed achieve a certain auxiliary function, but the existing guide glasses have simple functions and mainly stay in solving positioning, navigation, and travel problems, which are far from satisfying the daily needs of blind people. life needs

Embodiment 1

[0048] A kind of smart glasses for the blind, see figure 1 , comprising a spectacle frame 1, and a spectacle lens 2 and spectacle arms arranged on the spectacle frame 1; including:

[0049] AI camera 3: set in front of the spectacle frame 1; the AI ​​camera 3 is used for shooting to obtain an environmental image, and to identify the environmental image to obtain an image recognition result, and transmit the image recognition result to Processor 11;

[0050] Specifically, the AI ​​camera is electrically connected to the processor, and is used to transmit the recognized image recognition result to the processor. Preferably, there are three AI cameras, of which two AI cameras are embedded on both sides of the spectacle lens, and one is arranged in the middle of the spectacle frame; in this way, the AI ​​camera can capture the front horizontal direction 130 degrees of the smart glasses for the blind. °, the environment image within 96° in the vertical direction, the AI ​​camera ...

Embodiment 2

[0063] Embodiment 2 On the basis of Embodiment 1, an AI camera recognition method is added.

[0064] see figure 2 , the AI ​​camera is specifically used for:

[0065] S1: Recognize the environment image, obtain the physical characteristics of the obstacle, compare the obtained physical characteristics of the obstacle with the preset obstacle database, and obtain the name of the obstacle;

[0066] Specifically, the physical characteristics of obstacles include shape, size, etc., and the AI ​​camera can judge whether the obstacle is a person, car, or building based on the physical characteristics of the obstacle. For example, after the AI ​​camera recognizes, the name of the obstacle is played through the voice output module, such as "there is a car ahead", "there is a person ahead", etc.

[0067] S2: In the obtained N environmental images, perform target tracking on each obstacle, and obtain the behavior characteristics of the obstacle according to the position of each obsta...

Embodiment 3

[0079] Embodiment 3 On the basis of the foregoing embodiments, the following content is added:

[0080] The ultrasonic detection device is also used for:

[0081] When the ultrasonic wave detects that there is an obstacle ahead, adjust the ultrasonic emission angle of the ultrasonic emission head in the ultrasonic detection device; identify the orientation and size of the obstacle according to the distance of the obstacle in front detected by different ultrasonic emission angles.

[0082] Specifically, the angle of the ultrasonic emitting head in the ultrasonic detection device can be adjusted, so that the ultrasonic detection device can not only detect the distance of obstacles at one point, but also detect the distance of obstacles on one surface, so that it can identify The orientation and size of the obstacle.

[0083] In addition, the smart glasses for the blind also add navigation functions.

[0084] see image 3 , also including a voice input module 6 arranged under ...

Abstract

Smart glasses for blind persons provided by the present invention conduct shoot by an AI camera to obtain an environment image, the environment image is recognized to obtain an image recognition result, and the image recognition result is transmitted to a processor; ultrasonic waves are utilized to detect the distance of an obstacle in front and the detected distance is transmitted to the processor by a ultrasonic detection device; the received image recognition result and the distance of the obstacle in front is analyzed by the processor to obtain prompt information, and the prompt information is transmitted to a voice output module; and the received prompt information is played by the voice output module through voice. The smart glasses for blind persons can not only recognize the physical characteristics of static or dynamic objects, but also analyze the behavior of the objects. The amount of recognized information is greater, the accuracy is higher, the speed is faster, the functions are diversified, and the experience of users is improved.

Description

technical field [0001] The invention belongs to the technical field of glasses, and in particular relates to smart glasses for the blind. Background technique [0002] With the continuous development and progress of social science and technology, the degree of intelligence in society is getting higher and higher. While enjoying the convenience and speed brought by intelligence, people are also responsible for caring for some vulnerable groups in society. As a disadvantaged group in society, the blind (visually impaired or blind) are extremely inconvenient in walking and daily life due to lack of vision, and it is very important for them to perceive external things. [0003] At present, most of the blind people travel by relying on blind sticks to perceive blind roads and some obstacles on the road, and some rely on blind dogs to assist them in walking. Because the training of blind dogs takes a long time, and the number is limited and expensive, most blind people cannot pass...
