Claim 6:
7. The rotary imaging system of a rotary device according to claim 6, wherein if the rotating surface is not horizontal, the following steps are executed:
respectively acquiring the acceleration detection data of an up zero-crossing point and a down zero-crossing point; wherein the up zero-crossing point is a position with a highest relative horizontal plane of rotation of the third accelerometer, and the down zero-crossing point is a position with a lowest relative horizontal plane of rotation of the third accelerometer;
using a third period calculation formula to obtain the period number based on the acceleration detection data of the up zero-crossing point and the down zero-crossing point and the second rotation radius; the third period number calculation formula is:

T=2π/√{square root over (((a3up*COS θ+a4up*SIN θ+a3down*COS θ+a4down*SIN θ)/R2)/2)};

wherein, T is the period number, and a3up is the first direction detection data of the up zero-crossing point; a4up is the second direction detection data of the up zero-crossing point; a3down is the first direction detection data of the down zero-crossing point; a4down is the second direction detecting data of the down zero-crossing point; R2 is the second rotation radius; θ is a first predetermined angle.
