Description

Technical Field

[0001] The utility model relates to the technical field of shooting and target shooting, in particular to a high-precision laser shooting photoelectric target. Background Art

[0002] In traditional shooting training, coaches and athletes generally use real guns to gain shooting experience and maintain shooting habits to improve shooting accuracy. Since long-term shooting with real guns will waste bullets and is relatively costly, laser simulation transmitters are usually used to simulate shooting training to reduce training costs.

[0003] The patent document with application number CN202021696278.4 discloses an electronic target for a high-precision optoelectronic shooting system. The comparison document captures the landing position of the laser by taking photos through a CCD camera, and the MCD processor performs data processing after receiving the photos taken by the CCD camera, and accurately calculates and counts the position data of the laser landing point. The external computer can be connected to the MCU processor signal through the data transmission interface to receive the training data. However, due to the relatively small laser wavelength range captured by a single camera, the laser shot on the target surface cannot be accurately captured, and the training effect is affected because accurate training data cannot be collected. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a high-precision laser shooting photoelectric target which has a simple structure and can accurately capture the laser landing point, thereby facilitating the capture and identification of lasers of two wavelengths.

[0005] The technical scheme of the utility model is as follows: a high-precision laser shooting photoelectric target, comprising a shell; a target frame, arranged at the front end of the shell; a target surface, arranged on the target frame and capable of transmitting light; a camera module, arranged toward the target surface, comprising four groups of cameras arranged inside the shell and used for identifying images on the target surface; photosensitive components, arranged around the camera module and used for receiving frequency light; a fill light, arranged at the four outer corners of the camera module; a main control module, arranged at the rear side of the camera, the main control module comprising a circuit board and a power module arranged on the circuit board, the circuit board and the power module being electrically connected to the camera respectively;

[0006] It can be seen from the above scheme that the camera module is used to capture the laser wavelength, and captures the red light with a wavelength of 650nm and the infrared light with a wavelength of 850nm respectively. The photosensitive component is used to receive frequency light and assist the camera. The fill light is used to assist the camera to realize fill light when the pistol target and the rifle target are switched. The target surface is used for the light shot by the laser shooting gun body, and the camera is used to realize photo recording when the target surface recognizes that the light is emitted by the laser.

[0007] The front side of the shell is provided with a mounting frame, a first magnetic block is provided in the mounting frame, the target frame is connected to the front side of the mounting frame, and a second magnetic block magnetically connected to the first magnetic block is provided in the target frame. It can be seen that the target frame is detachably connected to the shell through the magnetic connection between the first magnetic block and the second magnetic block, which facilitates the disassembly and replacement of the target surface.

[0008] The target frame includes a first frame and a back plate buckled with the first frame, the first frame is provided with a mounting groove adapted to the second magnetic block, the surface of the mounting frame is provided with a limiting hole, and the four corners of the back plate are provided with guide posts corresponding to the limiting holes. It can be seen that the guide posts are inserted into the limiting holes to guide the target frame when it is installed on the mounting frame on the front side of the housing.

[0009] The mounting frame is provided with five groups of light guides, and the target frame is provided with through slots corresponding to the light guides. It can be seen that the five groups of light guides are used to record five consecutive shots in sequence, and the through slots are used for the light guides to pass through for light display, and whether effective shooting is performed is recorded by whether the light is bright or not, which facilitates the visualization of the number of shots.

[0010] The rear side of the housing is provided with a power supply interface and a data transmission interface. It can be seen that the power supply interface is used to realize power supply, and the data transmission interface is used to realize data transmission.

[0011] The shell is symmetrically provided with buckle grooves on both sides of the target frame. It can be seen that the buckle grooves are convenient for gripping when the target frame is disassembled, assembled or replaced.

[0012] The target surface includes a positioning surface and a shooting surface arranged on the upper side of the positioning surface, and the positioning surface is provided with positioning points. It can be seen that the camera module obtains the geometric center of the target surface by identifying the positioning points at the four corners of the positioning surface, thereby realizing the identification of the center of the target surface.
