1. A method for calibrating a digital rearsight of an auxiliary aiming device, wherein the auxiliary aiming device comprises:
a main body:
a digital sight; and
a ballistic compensation system;
wherein the digital sight and the ballistic compensation system are arranged at the main body;
the digital sight has the digital rearsight;
the ballistic compensation system comprises a range finder, a main control unit, an image processor, an image sensor and a display device;
the range finder is configured to measure a plurality of target distance data of the plurality of shooting targets and send the plurality of target distance data to the main control unit;
the main control unit is configured to calculate a ballistic compensation based on the plurality of target distance data and a calibrated data scale, and send the ballistic compensation to the image processor;
the image sensor is configured to obtain a target image;
the image processor is configured to send a recommended aiming position to the main control unit based on the ballistic compensation;
the main control unit is further configured to superimpose the recommended aiming position from the image processor onto the target image;
the display device is configured to display the target image superimposed with the recommended aiming position; and
the range finder, the image processor and the display device are all connected to the main control unit; and
the method comprises:
(S11) calibrating an aiming reference point of the auxiliary aiming device;
(S12) determining whether there is a new combination of the auxiliary aiming device and a ballistic trajectory, if not, proceeding to step (S13), if yes, proceeding to step (S14);
(S13) determining whether there are calibrated data scales corresponding to a plurality of shooting distances, if not, proceeding to step (S14), if yes, proceeding to step (S15);
(S14) sequentially performing calibration for the plurality of shooting distances to obtain the calibrated data scales corresponding to the plurality of shooting distances; and
(S15) loading the calibrated data scales corresponding to the plurality of shooting distances.
