Abstract

The invention relates to a Fresnel lens target device used for laser shooting. The Fresnel lens target device comprises a laser gun, a target surface, an image processing device and a shot indication computer. The target surface is of a transparent structure, and a shooting target graph is arranged on the target surface. A Fresnel lens is attached to the back face of the target surface. The image processing device is arranged at the focus of the Fresnel lens and connected with the shot indication computer through a data line. The target surface, the Fresnel lens and the image processing device are all arranged in a target box. The Fresnel lens is arranged in front of an image collection camera lens, light rays perpendicularly emitted in can be effectively focused, the image processing device is arranged at the focus of the Fresnel lens, and therefore accurate collection is achieved for the laser gun without interference of external parasitic light.

Description

technical field

[0001] The invention relates to a device for simulating shooting training with laser, in particular to a Fresnel lens target device for laser shooting, which belongs to the technical field of target recognition. Background technique

[0002] In weapon laser shooting training, it is more common to use CCD to shoot the laser landing point on the target surface for image recognition. But this method can only be used in a darker environment (such as indoors, backlight), and the target surface cannot be used in a very bright sunlight environment. Because the brightness of the sunlight is much higher than that of the conventional laser spot, the laser spot will be submerged in the sunlight on the target surface irradiated by the sun, and the CCD will not be able to collect the image of the laser spot. Contents of the invention

[0003] Aiming at the problems existing in the prior art, the present invention proposes a Fresnel lens target device for laser shooting...
