我把摄像头变成了乐器：从手势识别到 Web Audio，分享 5 个真正踩过的坑 最近做了一个有点不一样的浏览器小项目：用摄像头识别双手动作，再把手的位置和姿势映射成和弦、音高、音量和音色。 不需要安装软件，也不需要麦克风。打开网页、允许摄像头后，就可以隔空演奏。 项目地址：[GestureSynth.me]( https://gesturesynth.me/) 建议使用最新版 Chrome 或 Edge 。摄像头画面只在本地处理，不会上传。 ## 真正难的不是“识别到手” 最开始我以为，只要 MediaPipe 能返回手部关键点，剩下的事情就是把坐标转换成音符。 实际做下来发现：**识别出一只手很容易，让它变成一个“能演奏”的控制器才难。** 摄像头每一帧都会返回一组手部关键点，但这些坐标会轻微抖动，偶尔还会丢失。如果直接把原始坐标连接到音高或者音量，听起来会非常不稳定。 最后形成的处理链路大致是： ```text 摄像头 → 手部关键点识别 → 提取手掌位置、距离和手势 → 平滑、死区和状态保持 → 映

做的在线照相亭本来还有点流量，结果我 301 瞎整一通，彻底废了，重新上了一个站 地址：[freephotobooth.online]( https://freephotobooth.online/) 上面是老地址，本来流量还可以，上站第二天就有 300 个新点击，但我嫌弃域名后期没有品牌优势，所以 301 到了另外一个域名，但上了之后看到流量没有了，又很焦虑，然后又把新站 301 到老站，现在彻底 game over 不得已重新写了一个站，再上，有兴趣可以围观一下，看看哪个更好，有啥问题我可以改改，主打听劝 新站地址：[https://photobooth100.com/]( https://photobooth100.com/)
