行空板之“此时此景”吟诗精灵
【项目背景】
在日常生活中，我们经常会遇到令人心旷神怡的美景，无论是壮丽的山河、绚烂的日落，还是城市的繁华夜景，这些瞬间总能触动我们的心灵，激发我们想要用言语来表达赞美和情感的冲动。然而，并非每个人都有丰富的词汇量和文学素养，能够即兴创作出优美的诗句来充分表达内心的感受。为了解决这一问题，我们开发了这个项目，旨在通过技术手段帮助人们捕捉和表达对美景的感悟。【项目设计】 该项目通过行空板与USB摄像头、蓝牙音箱的结合，利用Python编程，实现了一个智能的图像识别和诗歌创作系统。当用户在看到美景并按下按钮时，系统会自动拍摄照片，并通过OpenCV库进行图像处理。接着，将图像上传至百度AI平台，利用fuyu_8b模型进行图片理解，生成描述性文本。然后，这些文本被送入百度的大语言模型中，提炼出主题，并据此创作出一首诗歌。最后，通过语音合成技术，将诗歌转化为音频，并通过蓝牙音箱播放，让用户能够以一种新颖而富有创意的方式，表达对美景的赞美和情感。这个项目不仅丰富了人们的表达方式，也使得艺术创作变得更加便捷和普及。【项目硬件】
【百度智能云千帆大模型】 本项目使用百度智能云千帆大模型，⼤语⾔模型使用ERNIE 4.0。 图像理解模型使用Fuyu-8B。【程序编写】1.OpenCV获取摄像头图像
