How do you calculate yaw pitch roll from accelerometer?
pitch = 180 * atan2(accelX, sqrt(accelY*accelY + accelZ*accelZ))/PI; roll = 180 * atan2(accelY, sqrt(accelX*accelX + accelZ*accelZ))/PI; navigation. accelerometer.
What do XY and Z mean on an accelerometer?
The X axis is parallel with the device's screen, aligned with the top and bottom edges, in the left-right direction. The Y axis is parallel with the device's screen, aligned with the left and right edges, in the top-bottom direction. The Z axis is perpendicular to the device's screen, pointing up.
