Technical Field

The invention relates to the technical field of laser, in particular to a laser multi-shooting-point identification system.

Background

Laser is another important invention of human beings after nuclear power, computers and semiconductors in 20 th century, and is called as "fastest knife", "best-line ruler" and "brightest light". The english name lightamplification by modulated emission means radiation means "amplification by stimulated emission light". The english full name of the laser has fully expressed the main process of making the laser. The principle of laser light was discovered by the famous american physicist einstein as early as 1916. The atoms are stimulated to emit light, hence the name "laser": when the electrons in the atoms absorb energy and then jump from a low energy level to a high energy level and then fall back from the high energy level to the low energy level, the released energy is released in the form of photons. The induced (excited) photon beam (laser) has highly uniform photon optical characteristics. Compared with a common light source, the laser has good monochromaticity, high brightness and good directivity. The laser is widely applied, and comprises laser marking, laser welding, laser cutting, optical fiber communication, laser ranging, laser radar, laser weapons, laser records, laser correction of vision, laser cosmetology, laser scanning, laser mosquito killer, LIF nondestructive testing technology and the like. Laser systems can be divided into continuous wave lasers and pulsed lasers.

The initial requirement for laser firing stems from military training. To reduce training costs, improve safety, and mitigate environmental impact, many countries have long begun investigating the use of simulated weapons for military training. In addition, with the popularization of computer technology and sensor technology, the realization of laser technology and virtual reality technology, military training by using simulated laser weapons has met very mature conditions. Therefore, many advanced training simulators are researched by various countries, and the training simulators can be roughly divided into two types, namely a simulated shooting system based on a laser technology and a scene simulation system based on a virtual reality technology.

Most of laser guns used in the existing laser shooting training capture the position according to the action of the laser gun by installing a gyroscope in the laser gun. This has the great disadvantage that the movement of the shot point cannot be recognized when the laser gun is moved in parallel without the deflection angle being produced. Errors are generated in an accumulated mode, the laser shooting device cannot be normally used, calibration must be performed frequently, only a single laser beam of shooting point can be identified and positioned, and the coordinates of multiple shooting points cannot be effectively identified and positioned.
