The invention provides a photoelectric position self-calibration mechanism, an electric seat and a vehicle, and relates to the technical field of seat control. The photoelectric position self-calibration mechanism comprises a light emitter, a light receiver, a position calibration pattern and a controller, the light receiver and the light emitter are both arranged on one surface of two opposite planes of an upper guide rail and a lower guide rail of the seat, and the intersection point of the axes of the light emitter and the light receiver is located on the reflecting surface of the opposite rail; the position calibration pattern is arranged on the reflecting surface, and in the sliding process of the upper guide rail relative to the lower guide rail, when an axis intersection point passes through the position calibration pattern, an optical signal received by the optical receiver reflects a coding waveform of the position calibration pattern; the controller is electrically connected with the light receiver, and the controller is used for self-calibrating the position of the seat according to the coding waveform. In the normal use process of the seat, position self-calibration is frequently carried out, the flexibility of seat position calibration is improved, the error of seat positioning is eliminated in time, and the accuracy of seat position positioning is improved.
