Technical Field

The invention relates to gun sighting telescope calibration, in particular to a gun sighting telescope calibration device based on a high-resolution camera.

Background

The base line synchronization between the gun and the fire control device of the tank is realized through a series of complex devices, and in practical use, the base lines of the gun and the fire control device can be deviated when the gun and the fire control device are transported for a long distance, placed for a long time, marched for a certain 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 benchmark is zero. 2. And (6) live ammunition correction. And the reference is reset to zero, namely a mirror is inserted into a gun muzzle, and the fire control and the reference of the artillery are synchronized through cooperation between the inside and the outside of the vehicle.

The traditional manual mirror inserting method adopts visual calibration, is long in time and large in error, and aims at the traditional reference calibration method.

Disclosure of Invention

The invention provides a gun sighting telescope calibrating device based on a high-resolution camera, which specifically comprises the following components: the device comprises a concentric matching barrel 1, a high-resolution camera module 2, a concentric cross target 3 and a processing and displaying module 4. The principle is that the concentric matching barrel is matched with the gun opening of the artillery, so that the center of the artillery is transferred to the center of a concentric cross target on a calibration device. The cross target on the calibration device is imaged by the high resolution camera module, and then the distant target at distance L2 is imaged. And after the centers of the two images are superposed in sequence, the gun muzzle is considered to be superposed with the center of the remote target, and the calibration of the gun reference is completed.

The high-resolution camera module 2 images the concentric cross target 3 and the remote target in sequence and wirelessly transmits the images to the processing and displaying module 4 in real time. The processing and display module 4 can receive the real-time image of the high-resolution camera module 2 in real time and calculate the deviation degree of the gun barrel and the remote target.

The artillery sighting telescope calibrating device based on the high-resolution camera is characterized in that: the concentric matching barrel 1 is a cylinder, the lower end of the concentric matching barrel is a cylinder with the diameter being 0.02 mm-0.10 m smaller than the diameter of the gun barrel, and the concentric matching barrel can be inserted into the gun barrel. The upper end of which can mount internally a high resolution camera module 2 and a concentric cross target 3.

The high-resolution camera module 2 can clearly image the short-distance concentric cross target 3 and the long-distance target and has the function of wirelessly transmitting images.

The concentric cross target 3 is composed of a circular optical flat sheet with a cross reticle and a target mounting ring. The concentricity deviation between the center of the cross reticle and the target mounting ring is better than 0.02 mm.

The processing and display module 4 has the function of receiving, processing and analyzing the image wirelessly transmitted by the high-resolution camera module.

And then, aiming the remote target through the gun sighting telescope, wherein the parallax is the deviation of the gun sighting telescope. And the center of the field of view of the gun sighting telescope is coincided with the center of the remote target through the adjustment of the adjusting mechanism, and the reference calibration process of the gun sighting telescope is completed.

The device greatly shortens the calibration time of the sighting telescope, improves the calibration precision, and has the characteristics of high precision, compact structure and portability.
