US12339100 - Auxiliary aiming device

The auxiliary aiming device features a digital sight and a ballistic compensation system that calculates and displays a recommended aiming position based on target distance data. The method for calibrating the digital rearsight involves determining new combinations of the device and ballistic trajectories, followed by calibrating data scales for various shooting distances.

Claim 1

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. 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.
