Deviation correction method in laser non-vertical incidence prism state, medium and equipment

The invention discloses a deviation correction method, a medium and equipment in a non-vertical incidence prism state of laser. The method comprises the following steps: actually measuring distance and angle data of a prism at a plurality of measurement times at different distances and different deflection laser incidence angles; calculating to obtain an angle deviation measurement error; fitting calculation parameters by adopting a least square method so as to obtain a continuous three-dimensional error curved surface; and taking the observation distance and the observation angle as the input of the continuous three-dimensional curved surface model, calculating to obtain an angle measurement correction number in the state, and correcting the measurement error of the total station according to the angle measurement correction number. Compared with original observation data before correction, the angle measurement correction number under different distances and different deflection laser incident angle states
