Discrete acceleration data to position
显示 更早的评论
I can get accelerator vector data from LEGO Accel sensor by every sampling time. For example when t=1 [x;y;z]=[15;9;220] when t=2 [x;y;z]=[7;5;221]
How can I transform acceleration data to position/displacement?

Many thanks~~~

I am not sure, but theoretically ,if you have acceleration, and you want to get displacement, you have to integrate to get velocity, and then integrate to get displacement. Try function cumtrapz() which enables you to perform numerical integration. However I think it is much better if you interpolate your displacement data to obtain an analytical expression of the displacement, and then integrate the expression twice to obtain an analytical expresion for acceleration.
