Description
Technical Field
The invention relates to calibration of gun sighting telescope, in particular to a gun sighting telescope calibration device based on laser indication.
Background
The base line synchronization between the gun and the aiming device of the tank is realized through a series of complex devices, and in practical use, the deviation between the base lines of the gun and the aiming device can be caused when the gun and the aiming device are transported for a long distance, placed for a long time, marched at a certain distance and time and replaced or maintained. So that at this time, a correction of the cannon is required.
The existing gun muzzle calibration is realized by manually inserting a mirror, and the correct posture of the gun is only seen by eyes without touching by hands, so that the gun calibration precision is influenced. The gun calibration is divided into two steps, 1, the intersection calibration of the gun axis and the sighting line of the sighting telescope (static gun calibration). 2. And (5) live ammunition correction. Static gun calibration is to insert a mirror at the gun muzzle and realize the long-distance intersection of the sighting line of the sighting mirror and the central axis of the gun barrel of the gun in cooperation with the inside and the outside of the vehicle.
The traditional manual mirror inserting method adopts visual calibration, has long time and large error, and aims at the traditional reference calibration method.
