The time stays at the target location including the time of photo taken(unit: second). For example: the Zenmuse P1 takes about 0.7s to take a photo. If you set stay time with 1s, the gimbal will stay for 0.3s after the camera has finished taking a photo. If the stay time is less than the photo time, the next PathPoint will be executed immediately after the photo is taken.
Euler target angle for roll (North East Down coordinate system). Unit: degree. You should use DJIGimbalParamAdjustRoll to get the adjustable roll range.
Euler target angle for pitch(North East Down coordinate system). Unit: degree. You should use DJIGimbalParamAdjustPitch to get the adjustable pitch range.
Euler target angle for yaw (Unit: degree). The yaw angle is relative to the aircraft heading. If you set yaw angle to 0 degree, the direction of the gimbal will be the same as the aircraft heading.
You should use DJIGimbalParamAdjustYaw to get the adjustable yaw range.
