Description

Technical Field

[0001] The utility model relates to the technical field of blind-aiding glasses, in particular to a pair of blind-aiding intelligent electronic glasses. Background Art

[0002] According to statistics from the World Health Organization, there are 40 million blind people in the world. Blind people have lost their vision and have difficulty understanding colors, shapes, distances, and movements, which has a huge impact on their daily lives and travel.

[0003] Traditional assistive tools for the blind, such as canes, require the blind to move the canes repeatedly to understand the situation in front of them, which is time-consuming and laborious. In addition, the detection distance of the canes is limited. They can only detect obstacles at the feet and cannot reflect the situation in the distance and in the air. Guide dogs can provide assistance to the blind, but the training and maintenance costs of guide dogs are high, which is difficult for ordinary families to afford. In addition, in some occasions, guide dogs cannot accompany the blind, so the assistance of guide dogs is limited. Bionic eyes can help the blind restore partial vision, but the implantation of bionic eyes requires surgery, which is expensive. In addition, bionic eyes are only suitable for blind people who are blind due to retinitis pigmentosa or age-related macular degeneration. Blind people with damaged optic nerves cannot restore partial vision by implanting bionic eyes.

[0004] Currently, the most widely used blind aids are mostly blind aid glasses, but there are some limitations in the current blind aids, which bring troubles and safety risks to the daily lives of the visually impaired. The following are some of the main problems:

[0005] Environmental perception limitations: Existing blind-assistance devices have limitations in environmental perception and cannot accurately identify the type and location of obstacles, such as whether they are steps, railings, or other objects. Navigation inaccuracy limitations: Navigation devices may be inaccurate in information judgment and unclear in communication due to interference from environmental noise or other situations, causing distress and safety risks to the visually impaired. For example, when a visually impaired person is walking on a busy street, due to a variety of factors, the navigation device may not be able to clearly indicate which direction they should go, or alert them to vehicles and pedestrians around them.

[0006] Patent CN112438837A discloses a pair of smart glasses that assist the blind, including an identification module and an operation module.

When storing and using, only the second section of the temple without other devices needs to be bent, which is conducive to the long-term use of the blind-aiding smart electronic glasses and is not easy to be damaged.

[0055] Specifically, the working process of the blind-aiding smart electronic glasses in this embodiment is as follows:

[0056] (1) The user enters the destination through voice recognition or handle operation to start navigation mode.

[0057] (2) The camera captures images of the surrounding environment and transmits them to the environmental sensing device via a data cable or wirelessly.

[0058] (3) The environmental perception device preprocesses the images captured by the camera, including operations such as denoising and image enhancement, to improve the accuracy of subsequent analysis. Then, the environmental perception device performs feature extraction on the preprocessed images to extract key features, such as edges, textures, colors, etc. These features can help identify obstacles, road signs, etc. Next, the environmental perception device uses computer vision technology, such as target detection algorithms or image classification algorithms, to analyze and process the extracted features to detect and identify key information such as obstacles and road signs in the image. Finally, the environmental perception device locates and tracks the object based on the detected position and features to determine its precise position and movement status in the environment.

[0059] (4) The positioning system uses UWB modules and UWB tags to locate the user. The UWB module is located inside the glasses and includes a UWB antenna and a UWB chip. The UWB antenna is responsible for receiving and sending UWB signals, while the UWB chip performs signal processing. The UWB tags are worn by visually impaired people or placed in key locations in the environment, such as corners and doorways. The UWB tags periodically send UWB signals. The positioning system uses the UWB positioning algorithm to process the signals between the UWB module and the UWB tag to calculate the user's location. Commonly used UWB positioning algorithms include distance-based positioning algorithms and angle-based positioning algorithms.

[0060] (5) The controller is responsible for processing and integrating data from various components and controlling the collaborative work between them. The controller will integrate the positioning data from the UWB module and may also integrate data from other sensors. Based on the integrated data, the controller will enable the blind-aiding glasses to update the environmental map in real time, identify potential obstacles or dangerous areas, and build an environmental map.

[0061] (6) The navigation device uses a path planning algorithm to calculate the optimal navigation path based on the user's destination and environmental map. The navigation device provides navigation guidance to the user through a user interface, which can be voice prompts, vibration feedback, or a visual interface, depending on the needs and preferences of the blind user. The navigation device can interact with the user to obtain information such as the user's destination input and navigation mode selection.

[0062] (7) The voice output device converts navigation instructions, warning prompts and other information into voice output and conveys it to the user.

[0063] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
