Sensor data processing - MetaWear CPRO
I'm running some tests with the metawear CPRO. With that porpose I decided to insert it in rugby ball and make some tests and get a better feeling of what can be achieved with this board.
However I'm facing some challenges with the data processing component. For example, in order to get the angle at which the ball is released, I would need to know the moment of release, however a simple threshold on the magnitude of the acceleration vector doesn't really work that well since different throws can have huge different acceleration vectors.
What would be some of your suggestions to solve this kind of problem and get even more useful data from the sensor readings?
Do you have any recommendations of similar projects to follow and get a better understanding or even articles/tutorials?
Thanks in advance
