The invention discloses a method for realizing servo last-stage angle measurement, which comprises the following steps of: S1, performing zero clearing on a last-stage angle, and converting angle data of a motor end of a servo mechanism into last-stage relative angle data; s2, initializing a calibration task; s3, turning a servo position searching switch for searching; s4, whether effective signal switching of the position switch is detected or not is judged, if yes, the last-stage angle is corrected, and the step S5 is executed; if not, turning to S3; s5, entering a working state, and accumulating final-stage angle data by using the angle data of the motor end of the servo mechanism; s6, whether effective signal switching of the position switch is detected or not is judged, and if yes, the last-stage angle is corrected; and if not, turning to S5. According to the scheme, the equipment quantity is small, the integration degree is high, the cost is low, high-precision measurement of the last-stage angle of the
