More Information
Summary:The invention relates to an automatic correction method and system for a sighting point of a sniper rifle. The method comprises the steps of obtaining a ballistic trajectory equation by analyzing thestress condition of a bullet in air, calculating the initial offset of the bullet through the ballistic trajectory equation, reversely solving an initial adjustment firing angle of the rifle by takingthe initial offset as an input parameter, further calculating impact point coordinates of the initial adjustment shooting angle under the shooting distance, comparing the impact point coordinates with a target position to obtain an initial offset, if the initial offset is not within a set deviation value range, adjusting the shooting angle through a least square method until a correction offset corresponding to the adjusted shooting angle is within the set deviation value range, determining a final shooting angle, and directly projecting the corrected aiming point on a sighting telescope, sothat the accurate calibrati
