Microscope rotation early warning system based on side observation

The invention discloses a microscope rotation early warning system based on side observation, and the system comprises an initial morphology obtaining module, a to-be-measured object position prediction module, a to-be-measured object movement position prediction module, a main lens rotation position prediction module, and a rotation collision judgment module. Judging whether the main lens collides with the to-be-measured object in the rotation angle range under the preset movement track of the measurement platform; in addition, a to-be-measured object target point obtaining module obtains a target point corresponding to the plane position of the lower edge of the main lens in the surface appearance of the to-be-measured object; the calculation amount of the controller is saved, and the calculation efficiency is improved; and the collision angle between the to-be-measured object and the main lens under the movement duration of the measurement platform is predicted through the rotation collision prediction mod
