摘　　要：为了正确培养青少年的阅读习惯,保护眼睛视力与健康,完成了一种基于机器视觉的阅读姿态矫正阅读支架。该阅读支架采用独特的结构设计,保证占用面积小,并采用伸缩夹书机构,满足日常看书和翻书需求。采用WS2812灯环和光敏电阻传感器组成自适应台灯,采用8Ω欧扬声器音频模块、Micro SD卡模块等电子元件组成语音播放模块实现台灯自适应调光、放置不同大小厚度的书籍、播放眼保健操等多功能的阅读支架。视觉部分采用Google开发的机器学习框架MediaPipe,配合机器视觉模型将坐姿分为6类:正常坐姿、左倾、右倾、前倾、后仰、托手。使用树莓派控制板以及USB摄像头实现阅读姿态识别以及通过语音播放模块进行姿态矫正。实验结果表明,该多功能阅读支架可放置不同大小厚度的书籍,满足大部分使用者的阅读需求,阅读姿态识别也能达到理想效果。In order to correctly cultivate the reading habits of young people,protect the eyesight and health,a machine vision-based reading posture correction reading stand was completed.The reading stand adoptd a unique structural design to ensure a small footprint,and adoptd a telescopic book-holding mechanism to meet daily reading and flipping needs.WS2812 lamp ring and photoresistance sensor were used to form an adaptive desk lamp,and an 8Ω speaker audio module,Micro SD card module and other electronic components were used to form a voice playback module to realize self-adaptive dimming of the desk lamp,placing books of different sizes and thicknesses,and playing eye exercises,etc.multifunctional reading stand.The vision part adoped the machine learning framework Media Pipe developed by Google,and cooperated with the machine vision model to divide the sitting posture into six categories-normal sitting posture,left leaning,right leaning,forward leaning,backward leaning,and supporting hands.Raspberry Pi control board and USB camera were used to realize reading posture recognition and posture correction through voice playback module.The experimental results show that the multifunctional reading stand designed can hold books of different sizes and thicknesses,which can meet the reading needs of most users,and the reading posture recognition can also achieve the desired effect.
