TensorFlow.js PoseNet 模型关键点动画

Question

我正在使用 TensorFlow.js pre-trained PoseNet model 从我的网络应用程序收集和存储 姿势数据。我已经有了一些 JSON 的块，其中包含要分析的关键点数据，以将其用作另一个神经网络的训练集。这是关键点数据示例：

问题是我需要一个界面来显示该数据，如果它是一个网络应用程序界面就完美了。我只发现 Google's demo app 使用 PoseNet 模型，关键点附加在 <canvas/> 中显示的网络摄像头视频的顶部，但它似乎使用了一些手动 canvas 绘图。

所以我很感兴趣，是否有一些库或非 JS 工具可以将关键点数据 视为动画关键帧，或者可以在它们之间手动滑动？还是我必须自己实施？提前致谢。

检查此存储库：https://github.com/ajaichemmanam/Posenet-ReactWebapp。它使用 React 制作一个用于显示 posenet 关键点的 webapp。
