Claim 5:
6. The rotary imaging system of a rotary device according to claim 2, wherein the acceleration detection component comprises a third accelerometer; by taking a connecting line between the third accelerometer and a rotation center of the circuit board as an axis, the third accelerometer has a first speed measuring direction deviating from the axis by a first predetermined angle and a second speed measuring direction deviating from the axis by a second predetermined angle; the acceleration detection data comprises first direction detection data corresponding to the first speed measuring direction and second direction detection data corresponding to the second speed measuring direction; the position parameter comprises a second rotation radius of the third accelerometer; a sum of the first predetermined angle and the second predetermined angle is 90 degrees;
the control module is further used for judging whether a rotating surface of the circuit board is horizontal based on the first direction detection data and the second direction detection data, and if so, using a second period number calculation formula to obtain the period number based on the first direction detection data, the second direction detection data and the second rotation radius; the second period number calculation formula is:

T=2π/√{square root over ((a3 COS θ+a4 SIN θ)/R)};

where T is the period number; a3 is the first direction detection data; a4 the second direction detection data; R2 is the second rotation radius; θ is a first predetermined angle.
