ml5.js 是一款基于 TensorFlow.js 的机器学习 JavaScript 库,可以轻松地为浏览器和 Node.js 开发人员提供机器学习模型。ml5.js 旨在使机器学习可访问并易于操作,即使对于那些没有深入了解机器学习的人来说也很容易上手。
<script src="https://unpkg.com/ml5"></script>
<canvas>
元素来显示视频流。可以像这样写:<canvas id="videoCanvas"></canvas>
<script>
const video = document.getElementById("videoCanvas");
if (navigator.mediaDevices.getUserMedia) {
navigator.mediaDevices
.getUserMedia({ video: true })
.then(function (stream) {
video.srcObject = stream;
})
.catch(function (error) {
console.log("Oops! Something went wrong: " + error);
});
}
</script>
<script src="https://unpkg.com/@tensorflow-models/posenet"></script>
<script>
标签中添加一段代码来加载 PoseNet 模型,并对视频流进行姿势检测:<script>
const poseNet = ml5.poseNet(video, function () {
console.log("Model loaded!");
});
poseNet.on("pose", function (results) {
console.log(results);
});
</script>
<script>
标签放在 <body>
标签的末尾。<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>ml5.js Example</title>
<script src="https://unpkg.com/ml5"></script>
<script src="https://unpkg.com/@tensorflow-models/posenet"></script>
</head>
<body>
<canvas id="videoCanvas"></canvas>
<script>
const video = document.getElementById("videoCanvas");
if (navigator.mediaDevices.getUserMedia) {
navigator.mediaDevices
.getUserMedia({ video: true })
.then(function (stream) {
video.srcObject = stream;
})
.catch(function (error) {
console.log("Oops! Something went wrong: " + error);
});
}
const poseNet = ml5.poseNet(video, function () {
console.log("Model loaded!");
});
poseNet.on("pose", function (results) {
console.log(results);
});
</script>
</body>
</html>
这样,我们就可以在 HTML 页面中使用 ml5.js,并利用其中的机器学习模型来进行姿势检测等操作了。
