kinect - Kinect快速手部追踪方法

Question

如何使用 kinect 跟踪快速手部运动？我已经尝试过 Openni 和 Microsoft sdk 来跟踪手。在他们两个身上，关节都有很多抖动和不准确的运动。

这是一个kinect水果忍者的示例视频：示例视频

在那段视频中，没有抖动和不准确，而且它还在跟踪快速的手部动作。

我错过了什么？是否有任何我应该研究的 kinect 硬件版本或类型。

My best guess is that Fruit Ninja applies some sort of smoothing at some point. What you're seeing in that video is almost certainly not the raw data they're getting from the Kinect. The data from the Kinect will always have some kind of jitter; real-world sensor data almost always does. You'll need to smooth it - exactly how to do that depends on the application; it could be something simple like modelling a kind of damping and/or inertia on the point that's being moved by the hand (which is what I suspect Fruit Ninja is doing), or you could look at something like a Kalman filter for a robust (but more computationally-intensive) way to reduce the noise in your sensor readings.
