广东东软学院本科生毕业设计（论文） 基于树莓派的幼儿认知辅助系统Children ‘s cognitive assistant system based on Raspberry Pi 摘要幼儿（0-3 岁）教育是人一生当中最先也是最为重要的教育。幼儿阶段的孩子主要通过观察、触碰、聆听来认识和了解世界，并且有着极强的模仿和习得能力。在这过程中，如果能及时满足孩子的认知需求，孩子的认知和听说水平将会得到大幅提升。在这过程中，如果能及时满足孩子的认知需求，孩子的认知和听说水平将会得到大幅提升。然而，现在有很多父母忙于工作，并且时刻在孩子身边进行认知引导，也很难实现。此外，家长发音所存在的准确度问题，对孩子可能造成误导。因此，开发具有物体识别和语音功能，能够及时对孩子触及的物品进行语音播报的系统，具有现实的应用价值和意义。本系统由树莓派、USB 摄像头和 3.5mm 音频接口的小音箱构成，主要功能是识别由 USB 摄像头捕获的图像中的物体并且把识别结果播报出来。与传统的早教系统相比，本系统采用 Tensorflow 实现智能物体识别和语音播报识别结果，更具智能性和实用性。实验结果表明，本系统识别过程约 9 秒，语音播报延迟时间约 0.02 秒，正确识别率 80%以上，能够满足系统使用要求。关键词：幼儿教育；树莓派；Tensorflow；USB 摄像头；物体识别1广东东软学院本科生毕业设计（论文）2广东东软学院本科生毕业设计（论文）AbstractThe education of children (0-3 years old) is the first and most important education in one's life.In early childhood, children learn and understand the world mainly by observing, touching and listening, and have a strong ability to imitate and learn.In this process, if the child's cognitive needs can be timely met, the child's cognitive and listening and speaking level will be greatly improved.In this process, if the child's cognitive needs can be timely met, the child's cognitive and listening and speaking level will be greatly improved.However, many parents are busy with their work and are always around their children for cognitive guidance, which is difficult to achieve.Moreover, the accuracy of parents' pronunciations...
