The invention relates to the field of measurement technology and can be used to measure the misalignment of the axis of the barrel and the sight axis.

Known used in artillery method and device for the alignment of the scope with gun [1]. In this way the alignment of the scope with the barrel of the gun at a target on the cut stem set the crosshair of the thin filaments that intersect with the axis of the barrel and breech of the barrel - tube alignment. With the help of manual actuators aiming line of sight bore passing through the tube alignment and the center of the crosshairs, combined with the index on viverone target. The disadvantages of this method and device is that when the alignment is not taken into account the shape of the bore, i.e. the curvature of the slice of the trunk.

The known method of control and set the long axis of the product relative to the base axis and a device for its implementation [2]. This method and apparatus is selected as a prototype. The disadvantages of this method of control and set the long axis of the product relative to the base axis and the device, its implements, can be attributed to the fact that the method declared in it, is not measuring method, and only performs a control function in a specified direction, for example the axes of the pipes with respect to some basic direction using the target channel, and it is Oh, it is very time consuming and takes a long time cycle.

The proposed method of measuring the mutual spatial arrangement of the axes of the barrel and sight, as well as automated television-optical system for its implementation allows you to automate the measurement process and to improve the accuracy of measuring the mutual spatial arrangement of the axes of the barrel and sight.

Automation of the measurement process and improving the accuracy of measuring the mutual spatial arrangement of the axes of the barrel and sight is achieved by the fact that in the inventive automated TV-optical system containing the measuring head with the electro-optical unit (EOB) and supports a camera with a charge coupled device (CCD), a computer with a monitor connected to the camera, added another EOB; the measuring head contains a locking device (FU), rotator (PU), in which there is fixed AOB and electrotherapist, housing FU and PU are designed so that their axes can radially move relative to each other in vertical and horizontal slits flat washers, seated on the hollow shaft of the actuator, in addition, PU is configured to preload the chassis PU to the inner surface of the barrel, turning it on 360° and fixing every 45° using supports and electric and hydraulic actuator; a rotator housing made in the form of a cylinder, the ends of which close two flange having one hole in the center and one rectangular cut-out on the edge, in which the bearing is made on the bellows, one of the flanges is attached on the center of the hollow shaft of the drive; in addition, the flanges include two fixed supports; housing EOB made in the form of a parallelepiped with cut corners and contains a camera and four mirrors in the truncated corners of the box at an angle of 45° to a horizontal axis, a mirror located in front of the camera, is translucent at the ends of the parallelepiped is fixed tube with two lenses, and one of the tubes contains two light sources, the tubes have two external cylindrical belt, through which case EOB installed on prism located in the rotating device, the axis of the cylindrical bands coincide with the axis of the CCD camera.

The method of measuring the relative position of the axes of the barrel and sight is pointing axes EOB located in the barrel and front sight, plane characters, and EOB located in the bore, rotate with PU 360°fix it every 45° the internal surface of the bore with the help of electro - hydraulic actuator, remember the image of the brands of the sign, located first, in the middle distance from the edge of the bore, and then away with the computer, determine the two points of intersection of the axis of the bore with the near and far planes of the characters; while other AOB placed on the eyepiece of the sight and remember using a computer point of the screen on the monitor on which to project the center of the aiming reticle image, then use AOB receive image turns or simultaneously near and far characters, then use the computer calculates the coordinates of the projection center of the aiming reticle on the near and far plane of characters in the coordinate system; coordinate four points obtained by the intersection of the axes of the barrel and sight near and far planes characters, calculate the four parameters describing the misalignment of the axes of the barrel and sight, namely the horizontal offset angle of the axis of the barrel and the sight axis, the vertical displacement angle of the axis of the barrel and the sight axis, the horizontal offset of the axis of the barrel and the sight axis, the vertical offset of the axis of the barrel and the sight axis.

The inventive automated television-optical system includes KI-8, power supply and control unit control centre controller 9, the computer 10 to the monitor 11.

GI consists of an optical unit AOB 12 used as a Metrology tool, a rotary device PU 13 and the locking device FU 14, and the axis GI 8 can freely radially displaced relative to the axis FU 14 and to provide a running GUY on the inner diameter of the bore 360° with fixation of the case KI-45°.

In the case AOB 15 are four mirrors 17, 18, 19, 20 and the camera 21, through the middle of all the mirrors on the optical axis of the camera 21 is channel 16. On the ends of the housing EOB two fixed tube 22, 23 and two outer cylindrical belts 24, 25 of the same diameter, the axes of which coincide with the axis of the CCD camera and form a common measurement axis app is RA. The tubes are the lenses 26, 27, which are able to move along the optical axis and to rotate around its axis with double eccentricity, as well as two light sources 28, 29. Four mirrors 17, 18, 19, 20 are located in the corners AOB 45° to the horizontal, the mirror in front of the camera is translucent.

Mirrors 17, 18, 19, 20 allow an overview of the trunk at the same time towards the breech and muzzle is pointing.

The rotator housing PU made in the form of a cylinder, the ends of which are fixed two flanges 31, 32 with holes in the center and is provided with three legs, two legs of each flange is rigidly fixed, and one bearing (35 or 36) of each flange is made on an elastic element (bellows). Inside PU fixed two prisms 33, 34, which is firmly fixed AOB 12 their boarding cylindrical belts 24, 25 located on the tubes 22, 23, which form the rotary device 13 General instrument axis. The flange 31 is attached by bearings the drive shaft 39. On the inner side of the flange 31 is attached to the hydraulic actuator 40 on the bellows 41.

On the hollow shaft of the actuator 39 is movable sits washer 37 with a Central vertical slot 44 for the shaft and two horizontal slots 42, 43 along the edges to mate with FU shaft 14 by means of screws 48, 49. The vertical line is the first slot 44 and a horizontal slot 42, 43 washer 37 allow the body axis PU 13 radially displaced relative to the axis FU 14 when rotated 360°.

The automated TV-optical system is as follows:

In the slice channel of the barrel insert GI 8 so that FU 14 were from the cut stem. With the help of nuts 45 throw levers 46, 47 and fix FU 14 in the bore. On the command of the computer 10 via the controller MCR 9 carry out the actuation of the electric drive 38 and the hydraulic actuator 40, which causes the supports 35, 36 to be nominated and to put pressure on the inner surface of the bore. Thus, the corps GI 8 is pressed hard legs to the opposite surface of the bore and is fixed.

At this time, the camera 21 carries out photographing images of the middle mark. Further, the actuator 38 rotates the casing PU 13 relative to the housing FU 14 45° and upon detecting PU 13 camera 21 photographs the next character position. Rotating thus GI 8 360°get on the monitor 11 eight sign with coordinates of the center point "O"around which they rotate. The coordinates of this point are the coordinates of the point of intersection of the axis of the barrel with the plane of the sign. Then the same operation is repeated to determine the point of intersection of the axis of the barrel with the plane far of the mark.

To determine coordinatori the intersection of the sight axis with the plane of the sign of the second EOB put on prism about sight and rotate it 360° and thus receive the point of intersection of the sight axis with the plane of the sign in the middle and long distances.

The inventive method of measuring the relative position of the axes of the barrel and sight is the following. In the slice of the barrel is placed measuring KI-8, consisting of PU 13, AOB 15 and FU 14. Then PU 13 measuring head separat in the slice channel of the barrel by FU 14.

On the ground at a certain distance from the edge of the bore in the field of view AOB 15 install sign with glowing marks. Then the program embedded in the computer 10, KI-8 turn inside the barrel relative to the fixed axis, FU 14 360° with fixation of 45°. For a fixed position of HI 8 camera EOB performs photographing images of luminous marks sign on the screen of the monitor receive eight provisions of the token.

Computer using the specified program automatically analyzes the image and calculates the coordinates of the point of the sign around which the image rotates. The coordinates of this point in the system of the mark and the program calculates the distance to the sign determines the point of intersection of the slice axis of the barrel with the plane of the sign.

Then determine the direction of the axis of the sight. On the prisms set AOB, which must be a sign, then AOB rotate 360° with fixation of 45°. The program analyzes when atie image of the sign and calculates the coordinates of the point around which they rotate. The coordinates of this point in the system sign determine the point of intersection of the sight axis with the plane of the sign.

Then sign on the ground move at a greater distance from the edge of the trunk and carried out the same operations on the coordinates of points of intersection of the axis of the barrel and the sight axis with the plane of the remote token, as described above.

Using the program embodied in the computer calculate the four parameters describing the misalignment of the axes of the barrel and sight, on the obtained coordinates of points of intersection of the axes with planes near and remote character:

- the horizontal angle of the axis of the barrel and sight;

- vertical angle to the axis of the barrel and sight;

- the horizontal offset of the axis of the barrel and sight;

- vertical movement axis of the barrel and sight.

The knowledge of these four parameters allows you to define the offset of the axis of the barrel relatively to the axis of the sight.

Technical solutions, the underlying construction of the automated TV-optical system and the proposed method, executed on a modern level of development of electronics using domestic components. The inventive system will be used in the device for measuring the misalignment of her barrel and sight (TIS) Nizhny Novgorod research priborostroe the high Institute.
