Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of blind auxiliary tools, and particularly relates to a multi-modal intelligent glasses for visually impaired people. Background Art
[0002] Data from the China National Blindness Council in 2019 showed that there were 17.31 million people with visual disabilities in China, accounting for one-fifth of the total number of visually impaired people in the world, making China the country with the largest number of visually impaired people in the world. Facing such a large group, their travel problems are particularly prominent. At present, visually impaired people mainly rely on three methods to travel: barrier-free facilities, using a cane to explore the way, and being led by a guide dog. Moreover, there are no means of transportation specifically designed for visually impaired people to use on the market, and the surrounding products are also quite scarce. As of 2021, the adaptation rate of disabled aids in China was only 62.9%, far from meeting the growing needs of disabled people. Therefore, auxiliary devices suitable for visually impaired people urgently need to be improved and innovated.
[0003] Currently, most existing intelligent glasses use a single camera. However, due to the limitations of a single camera, the effect of position ranging is often not ideal. For example, a single camera can only capture information from one angle, its ranging range is limited by the camera's focal length and the size of the object, and it cannot obtain depth information through parallax, resulting in relatively limited information provided by a single camera when performing three-dimensional reconstruction or scene understanding. Existing auxiliary devices for visually impaired people are also equipped with many practical functions, but in terms of function switching, the traditional button method is adopted. Due to the perspective problem, such function switching is rather inconvenient, especially for visually impaired people and the elderly who may not be able to accurately find the position of the button. In addition, the position information, physical health, and mental health of visually impaired people all need to be paid attention to in a timely manner. Content of the Utility Model

[0025] Embodiment 1
[0026] This embodiment provides a multi-modal intelligent glasses for visually impaired people, as Figure 1 shown, it is a schematic structural diagram of the multi-modal intelligent glasses for visually impaired people in this embodiment.
[0027] The multi-modal intelligent glasses for the visually impaired proposed in this embodiment include a frame 1. First temple 101 and second temple 102 are respectively connected to both sides of the frame 1. A binocular camera module 2 is provided at the center of the frame. An earphone module 4 is provided at the connection of the first temple 101 and the frame 1. The frame 1 is also provided with a plurality of electroencephalogram signal acquisition modules 5. Temporal artery signal acquisition modules 6 are provided at the ear supports of the first temple 101 and the second temple 102. The binocular camera module 2, the earphone module 4, the electroencephalogram signal acquisition module 5, and the temporal artery signal acquisition module 6 are respectively communicatively connected to an external main control processing device 9 through a wireless transmission module 3.
[0028] In this embodiment, the earphone module 4 is used to realize the human-computer interaction between the wearer and the glasses. The instructions of the wearer will be received by the earphone module 5 and communicated with the main control processing device 9 through the wireless transmission module 3. After the main control processing device 9 processes the information, the result will be returned to the earphone module 5 to output voice information or realize function switching, so as to realize human-computer interaction by voice. When it is detected that the wearer turns on the binocular ranging function, the binocular camera module 2 will collect information and transmit the information to the main control processing device 9 through the wireless transmission module 3. The main control processing device 9 analyzes and processes the collected information. After the processing is completed, the result will be returned to the wireless transmission module 3 and transmitted to the earphone of the earphone module 5 to play the data processing result in voice form. In addition, the electroencephalogram signal acquisition module 5 is placed on the side of the frame close to the wearer's forehead. The three acquisition electrodes inside the electroencephalogram signal acquisition module 5 located at the center and both sides of the frame can collect the electroencephalogram signals of the triple conductive potential Fp1, Fpz, and Fp2 in the frontal lobe area of the wearer. The temporal artery signal is collected by the temporal artery signal acquisition module provided at the ear support of the temple. The collected electroencephalogram signals are transmitted to the main control processing device 9 through the wireless transmission module 3 and then analyzed.
[0029] It should be noted that relevant processing programs are preset in the main control processing device 9, which are routine settings for those skilled in the art to perform instruction analysis, ranging processing, or physiological information acquisition according to voice signals, binocular images, or body signals. Therefore, it will not be described in detail here.
[0030] In an alternative embodiment, an acquisition electrode and a digital-to-analog conversion module are provided inside the electroencephalogram signal acquisition module 5, and the acquisition electrode is electrically connected to the digital-to-analog conversion module.
[0031] Further, a digital-to-analog conversion module and a digital-to-analog conversion module are provided inside the temporal artery signal acquisition module 6, and the acquisition electrode is electrically connected to the digital-to-analog conversion module.
[0032] As an exemplary illustration, the electroencephalogram (EEG) signal acquisition module 5 is placed on the side of the frame close to the wearer's forehead. The acquisition electrodes inside the EEG signal acquisition module 5, located at the center and both sides of the frame, can collect the EEG signals of the triple conductive potentials Fp1, Fpz, and Fp2 in the frontal lobe area of the wearer.
[0033] In this embodiment, the physiological information of the wearer can be collected through the acquisition electrodes inside the EEG signal acquisition module 5 and the temporal artery signal acquisition module 6. Subsequently, the captured analog signal is converted into a digital signal by the analog-to-digital conversion module, and then the digital signal is transmitted to the wireless transmission module for subsequent processing.
[0034] In this embodiment, the ranging function is realized through a binocular camera; compared with other single-camera smart glasses, the algorithm for distance detection by the binocular camera is more accurate, and it has strong anti-interference ability in the case of large light changes or complex environments; the man-machine interaction is realized through the earphone module, and information consultation or function switching can be carried out according to needs. Compared with the traditional button setting, it enables visually impaired people to achieve man-machine interaction more conveniently; the physiological information of the wearer is collected through the acquisition module. For example, the EEG signal of the user is obtained through the triple conductive potential on the forehead, and the EEG signal is decomposed into five brain characteristic rhythms for analysis, which not only avoids the problem of high energy consumption of multi-potential association conduction, but also avoids the problem of single information of the EEG signal of single-conductive potential. In addition, when the main control processing device 9 realizes the heart rate detection function, the temporal artery signal is obtained through the signal acquisition module at the temporal artery, and the heart rate of the wearer is calculated, providing a key evaluation index for the wearer's physical health. After obtaining the physiological information, the acquired analog signal will be first converted into a digital signal to avoid data loss or noise interference problems in the subsequent transmission process.
