Laser target identifying system based on character pictures and identifying method of laser target identifying system

Abstract

The invention relates to a laser target identifying system based on character pictures and an identifying method of the laser target identifying system. The laser target identifying system comprises a scene generating unit, a display unit, at least two laser transmitting parts, an image collecting unit, a filtering device and a target resolving unit, and further comprises at least two micro-diffraction optical elements, wherein the micro-diffraction optical elements correspond to the laser transmitting parts one by one; the micro-diffraction optical elements are arranged between the laser transmitting parts and the display unit; the character pictures generated by each micro-diffraction optical element are different. The laser target identifying system provided by the invention can be used for identifying a plurality of laser targets through the single image collecting unit, so that resources and spaces can be saved; the laser target identifying system can be widely applicable to various shooting simulation systems.

Description

technical field [0001] The invention belongs to the technical field of target recognition, in particular to a feature pattern-based laser target recognition system capable of real-time recognition of multiple different laser target types and light point coordinates in the same environment. [0002] Background technique [0003] Laser target recognition is mainly used to generate interactive responses in three-dimensional scenes of human-computer interaction, such as in weapon simulation shooting systems. The existing laser target recognition system adopts the recognition technology based on the laser wavelength. The existing laser target recognition system is composed of a scene generation unit, a display unit, a laser emission unit, an image acquisition unit, and a target calculation unit. If the existing technology needs to identify multiple weapon simulators, it is necessary to add a simulator for each additional simulator. There are image acquisition units and filter d...

AI Technical Summary

Problems solved by technology

The existing laser target recognition system is composed of a scene generation unit, a display unit, a laser emission unit, an image acquisition unit, and a target calculation unit. If the existing technology needs to identify multiple weapon simulators, it is necessary to add a simulator for each additional simulator. There are image acquisition units and filter devices corresponding to different wavelengths, resulting in waste of resources and space, and this prior art is limited by the wavelength of the laser, so it cannot be expanded in large quantities, and the types of targets that can be recognized are limited, which also limits the number of recognized targets.
