Abstract

FIELD: weapons and ammunition.

SUBSTANCE: invention is related to a method for parameters fixation of all small shots in the target zone of a flying target by equipment during firing from smooth-bore weapon. Method includes colouring a shot with luminescent paint with addition of aluminium powder, placing three high-speed video cameras along x, y, z axes to grip the target zone of a flying target, illumination of the target zone with laser and ejection of at least one cartridge, which shot charge flight parameters are fixed by high-speed video cameras. Axis x is a direction perpendicular to the shots flight path and vertically directed from top in the target area of a flying target. Axis y is a horizontal direction, perpendicular to the shot flight path. Axis z coincides with direction of the shot flight path. Laser is made with the possibility of expansion of the light beam.

Description

FIELD OF THE INVENTION

The invention relates to the field of physical education and can be used in sports of the highest achievements to adjust and improve the training of athletes in trap shooting.

State of the art

There is a method of fixing the parameters of all pellets in the zone of defeat of a flying target when shooting from smoothbore weapons (http://www.youtube.com/watch?v=nux2kz-3i8g, published on 02.25.2010), including the installation of one high-speed video camera in the affected zone of a flying target in a direction perpendicular to the flight path of the shot, shooting at least one cartridge, the shot charge flight parameters of which are recorded by a high-speed video camera. The disadvantage of this analogue is the lack of accuracy (insufficient visibility) of the determination and fixation of all grains by the camera in the affected area of the flying target, since there is no illumination of all grains (many of which merge with the background landscape), in addition, the use of one camera makes it difficult to fix and determine the parameters and the presence of grains from other angles from the camera.

Disclosure of invention

The technical result consists in fixing the parameters of all the grains in the affected area of the flying target by the equipment and is achieved due to the better location of several cameras from different angles and the illumination of each pellet. The method for fixing parameters of all pellets in the zone of defeat of a flying target by equipment when shooting from a smoothbore weapon includes the following steps: fixing the position of the bar of a smoothbore weapon relative to the target, staining the shot with a layer of luminescent paint with the addition of aluminum powder, installing three high-speed cameras along the x, y, z axes, made with the possibility of capturing the affected area of the flying target, where the x axis is the direction perpendicular to the flight path of the shot, directed vertically from above in the affected area of a flying target, the y axis is the horizontal direction perpendicular to the flight path of the fraction in the zone of defeat of the flying target, and the z axis is the direction of the flight path of the fraction in the zone of defeat of the flying target, highlighting the target zone of the target with at least one laser configured to expand its light beam shooting at least one cartridge, the shot charge flight parameters of which are recorded by high-speed video cameras.

According to the invention, the establishment of three high-speed video cameras is configured to create a three-dimensional computer model of a shot sheaf in the affected area of a flying target.

According to the invention, the laser is made green with the possibility of expanding its light beam with a diameter of up to 2.5 meters at a distance of 35 meters.

According to the invention, each pellet colored with luminescent paint with the addition of aluminum powder and illuminated by a green laser is clearly visible relative to the target in the video frame.

According to the invention, each high-speed camera is configured to take up to 10,000 frames per second.

According to the invention, the parameters of each shot are fixed, such as the speed in the affected area of the flying target, the shape of the shot sheaf, the position of the shot sheaf relative to the flying target, the accuracy of the shot.

According to the invention, a high-speed video camera along the z axis is fixed under the barrel of a smoothbore weapon in the direction of the shot.

Brief Description of the Drawings

The invention is illustrated in FIG. 1, which shows a diagram of a preferred embodiment of the claimed invention.

The implementation of the invention

The method for fixing parameters of all pellets in the zone of defeat of a flying target (see Fig. 1) when firing from a smoothbore weapon includes the following steps: fixing the position of the bar of a smoothbore weapon 1 relative to target 2, staining the shot 3 with a layer of luminescent paint with the addition of aluminum powder, setting three high-speed cameras 4 along the x, y, z axes, made with the possibility of capturing the affected area of the flying target 2, where the x axis is the direction perpendicular to the flight path of the shot (or shot sheaf), directed vertically from above to the zone of destruction of the flying target 2, the y axis is the horizontal direction perpendicular to the flight path of the fraction (or shot sheaf) to the zone of destruction of the flying target 2, and the z axis is the direction of the flight path of the shot (or shot sheaf) to the zone of destruction of the flying target 2 , illumination of the affected area of the target 2 by at least one laser 5, configured to expand its light beam 6, shooting at least one cartridge, the flight parameters of the shot charge (or shot sheaf, or shot) which is fixed Speed cameras 4.

In a particular embodiment of the invention, the high-speed video camera 4 along the z axis is fixed under the barrel of the smooth-bore weapon 1 in the direction of the shot.

Each pellet when stained with luminescent paint with the addition of aluminum powder and illuminated by a green laser is clearly visible relative to the target in the video frame, which allows the equipment (cameras) to technically more accurately and quickly determine the position of a particular pellet relative to the target (target) due to the contrast of each illuminated pellet on the rest (mainly the back) background and the presence of three high-speed cameras on the three axes x, y, z. In this case, it should be noted that the illumination of each pellet can be performed in any other known manner.

In addition, in a private embodiment of the invention, all three video cameras can be connected to a control unit (or, for example, to a computer or microcontroller), configured to process information from multiple cameras and create, for example, a three-dimensional computer model of a shot sheaf in the affected area flying target.
