Automatic correction method and system for sighting point of sniper rifle

Abstract

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 calibration of the aiming point can be quickly realized by utilizing the method and the system, the correction speed is far higher than the manual correction speed, the method and the system can adapt to various complex environments, and a direction is provided for the research of new-generation sniper rifle aiming equipment.

Description

technical field [0001] The invention belongs to the technical field of light weapon shooting, and in particular relates to a method and a system for automatically correcting an aiming point when a sniper rifle shoots a fixed target. Background technique [0002] The trajectory of a sniper rifle bullet has a set of ballistic trajectory calculation equations. The trajectory is affected by many factors such as air temperature, air pressure, wind direction, wind speed, air humidity, shooting angle, bullet speed, and gravity. The trajectory is an offset arc. . The sniper rifles configured by the military of various countries are equipped with ballistic tables, which are the main reference for snipers when shooting long-distance targets. [0003] Snipers need to use aiming equipment when shooting long-distance targets. When shooting, the shooter needs to fully consider the influence of external factors and target distance on the trajectory, and correct the aiming point based on h...

AI Technical Summary

Problems solved by technology

[0004] Shooting accuracy and adaptability to the battlefield environment are important indicators for the design and research of sniper rifles. There are three deficiencies in the current manual calibration of sniper rifles: First, when the external environmental factors are complex, the sniper may not judge the environmental factors properly. Accurate, resulting in incorrect calculation of the ballistic trajectory; second, due to psychological stress or other factors, adjustment errors when correcting the height of the scope and the left and right knobs; third, the initial position cannot be found after adjusting the scope knob many times, resulting in errors in all subsequent corrections

[0005] Therefore, so far, there is a lack of effective methods and systems to automatically analyze environmental factors and automatically correct the aiming point, thereby improving the shooting accuracy of the sniper rifle and the adaptability to the war environment
