Abstract

This invention discloses an automatic target-reporting method and system for indoor and outdoor bullet shooting. It includes veiling sensor array, signal collection, coordinates computation and display parts. The basic cell array of the veiling sensor is composed of a linear light source L and corresponding receiving device. The linear light source L is composed of light-emitting diodes that are arranged in line. The receiving device S is formed by the end face of optical fiber. The veiling sensor is three-dimensional frame structure. Two parallel veiling are used together in the X and Y computed coordinate directions. Each of them has two V shaped veiling which form alpha angle with the two parallel veiling. Thus, they form the special veiling sensor array. Only four sets of veiling basic cell arrays can fulfill the three-dimensional no touch measurement of the bullet. It can give the exact location and speed of the bullet on the target. The rate of false reporting rate is low. It will not be interfered by adjacent target.

Description

technical field

[0001] The invention belongs to the technical field of an automatic target reporting device and method for bullet shooting, and mainly relates to an automatic target reporting device using light curtain technology, specifically a light curtain array automatic target reporting device and method. Background technique

[0002] In the shooting training of shooting entertainment, army, public security department and the competition, the statistical method of shooting performance has artificial target reporting and automatic target reporting. Manual target reporting is the most traditional and primitive method, which has many disadvantages, such as personal subjectivity, difficulty in identifying heavy holes, time-consuming and laborious, and certain dangers. With the advancement of technology, various automatic target reporting technologies continue to emerge. Automatic target reporting overcomes the disadvantages of manual target reporting, but there are still la...
