Track the velocity(or average velocity) of a basketball being dribbled
I'm trying to get the velocity of a dribbled basketball while someone is wearing the sensor on his or her wrist.
I'm a noob at best and i'm lost. I purchased a metawear c. For a while now I've been trying to figure out a way to extract the velocity from the stream of data. To some extent I understand that the data received will show error. I have tried the V = V0 + (forms of acceleration * time), the data seems to be accumulating.
I have 3 questions.
1. Am I lacking an additionally sensor which would make my task astronomically easier?
2. Is there a way I can get a rough estimate on an algorithm (example: Have a set time step like 0.1 sec and taking the average of the data between the time step) to get closer to an actual reading? or Kalman filter?
3. Am I asking the wrong questions because of a lack of knowledge?
