Embodiment 1

[0049] This embodiment provides an adaptive adjustment method based on AR smart learning glasses, such as figure 1 shown, including the following steps:

[0050] S1. Obtain the video image information captured by the image acquisition module, select a feature information in the video image information as the first image feature information, and adjust the image acquisition module by the preset ratio threshold of the first image feature information in the video image information focal length and offset information, the offset information includes offset direction and offset distance;

[0051] S2. Acquire the sound information captured by the sound pickup module, and select and lock a sound feature information in the azimuth as the first sound feature information, establish a sound amplification and denoising model, and remove other sound information except the first sound feature information. ;

[0052]S3. The detection module acquires the trajectory information, offset infor...

Embodiment 2

[0058] On the basis of Embodiment 1, this embodiment also includes the steps of manual zooming and automatic focusing, as follows:

[0059] The normalized contrast value of the first image feature information under natural light and measurement light is acquired, and the normalized contrast value is used as a reference value for focusing of the lens, and the reference value is automatically adjusted.

[0060] further, as figure 2 As shown, this embodiment includes a camera 102, an optical sensor 103, an MCU 101, an SD card 104, a display module 105, an indicator light 106 and a button module 107. The camera 102 is connected to the optical sensor 103, and the signal terminal of the optical sensor 103 is connected to the The signal terminal of the MCU 101 is connected to the signal terminal of the SD card 104 , and the signal terminal of the SD card 104 is connected to the MCU 101 .

[0061] This embodiment aims at the disadvantage that after students change the shooting dista...

Embodiment 3

[0063] On the basis of Embodiment 1, the present embodiment also includes the step of converting text by speech, which is specifically as follows:

[0064] Acquire first sound feature information, compare the acquired first sound feature information with data in the database, obtain text information corresponding to the voice, and convert the text information into TXT format.

[0065] The speech-to-text described in this embodiment can convert the content of the teacher's lectures in the classroom into text, and save the converted text in TXT format and record it in the memory.

[0066] Further, as image 3 As shown, this embodiment includes a high-sensitivity unidirectional MIC 201, an omnidirectional MIC 202, an amplifier 203, a noise reduction module 204, a microprocessor 205 and a CPU 206, and the high-sensitivity unidirectional MIC 201 is connected to the noise reduction module 204 through the amplifier 203 , the omnidirectional MIC 202 is connected with the noise reduct...

Abstract

The invention discloses an adaptive adjusting method, a pair of AR intelligent learning glasses and an AR intelligent learning system. The AR intelligent learning glasses include an image collection module, a pickup module, a detecting module, an analysis module, a storage module and a data transmitting module, the system composed of the AR intelligent learning glasses includes a cloud server, a mobile terminal and a PC. The adjusting method of the AR intelligent learning glasses includes: current orientation of the image collection module and the pickup module is obtained, a moving track andoffset information of the head of a user are captured, a data offset model is established, and the image collection module is adjusted. The problem that image information which is in a far distance cannot be clearly captured and remote sound information cannot be restored by a traditional image capturing device is solved, locking can be performed on characteristics information in an image capturing range and automatic regulation of an offset distance can be performed, the method can be adaptive to the user head in the motion state, and an offset direction and an offset distance of the image collection module can be adjusted.

Description

technical field [0001] The invention relates to the technical field of intelligent wear, in particular to an adaptive adjustment method, AR intelligent learning glasses and a system. Background technique [0002] With the rapid development of social economy and the change of modern education mode, traditional learning modes such as listening and reading have become less and less suitable for fast-paced learning life. It is difficult for students to take notes for later review while listening to lectures. The voice recorder developed by the existing electronic product company for the situation, but the voice recorder cannot capture the image of the teacher's lecture and the written record on the blackboard, and also has great defects. [0003] With the development of smart wearable technology, people's visual experience and hearing experience have been greatly changed, such as existing smart watches, VR smart glasses, AR smart glasses, etc., and even some products have camer...
