c++ - 在 Leap 运动中计算工具的加速度

Question

I am trying to create a virtual drum with leap motion. If a stick go fast and changes its direction in a moment (means high acceleration), I will count it as a "hit". The problem is I cannot calculate the acceleration of my tool (stick). I checked official documentation entirely however I did not see any function that finds the acceleration. Is there any method that I can calculate the acceleration of a tool ?

Answer 1

您可以通过对速度求导来跟踪加速度；请注意，它可能对错误很敏感并需要一些过滤。

Answer 2

我喜欢虚拟鼓的项目！无论如何，这就是我的做法：如果您将“击中”视为 SwipeGesture，您可以获得手势的速度，如果速度比您的“击中阈值速度”快，您认为 Swipe 为“击中”鼓！！！这是 Swing 手势速度的文档https://developer.leapmotion.com/documentation/cpp/api/Leap.SwipeGesture.html#cppclass_leap_1_1_swipe_gesture_1a055e9dc8167598af360254f4775a27c9
