Hi there community,
I am currently doing a self project to better understand the use of 9axis IMU and physics + to improve my coding. My project is targeted more toward measuring the speed and distance travel by a toy car. With many forum and research article read I was able to obtain the linear acceleration (compensate gravity) thru the help of madgwick. So now i am struck with my next step which is obtaining the velocity. I have done integration as shown in the code attached, i obtaining the result i want it increase as i move the car and decrease when it stop however the drifting problem was pretty bad due to error accumulated . For my use case i just want to know if the car is moving or so it does not have to be a definite 0 (due to the limitation of low cost sensor) but must be close to 0.1~0.7 as i can set a threshold to indicate the motion of the car.
So recently I have come across an article on instantaneous velocity meaning to calculate velocity every time interval however due to my limitation in coding i was not able to achieve this part hence will like to seek advice from your guys on how i can implement it with my current code!
thank you in advance
