Description

Technical Field

[0001] This invention relates to the field of wargaming and intelligent interaction technology, specifically to an electronic wargaming system and electronic wargaming identification method based on optical positioning. Background Technology

[0002] Traditional wargaming uses physical sand tables, maps, and various pieces representing combat units, with referees manually recording and adjudicating the games. This method suffers from drawbacks such as inefficiency, susceptibility to errors, difficulty in reviewing games, and limitations in performing complex calculations. With the development of computer technology, fully digital wargaming software has emerged. While offering superior computing power, it has lost the intuitiveness, tactile feedback, and collaborative atmosphere of physical wargaming.

[0003] Existing technologies also include attempts to combine physical and digital methods, such as embedding RFID chips on the bottom of the pieces and deploying RFID reader arrays under the map for positioning. However, these solutions are costly, inflexible in deployment, and struggle to identify the multifaceted states of the pieces. Another approach is to use a top-mounted camera for visual recognition, but this presents challenges in terms of accuracy and reliability when the pieces are densely packed, occluded, or when identifying the side states of the pieces is required.

[0004] Therefore, there is an urgent need for an electronic wargaming solution that is low-cost, flexible in deployment, fast and accurate in identification, and can retain the advantages of physical wargaming. Summary of the Invention

[0025] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.

[0026] like Figure 1 and Figure 2 As shown, the system includes a flexible base layer 1, which includes a curtain 11 and a frame 12 disposed on the curtain 11. The frame 12 consists of multiple parallel iron sheets forming a grid structure. Several light strips 13 are arranged in the gaps between the grid structures, and each light strip 13 is equipped with several independently controllable LED units. Specifically, the frame 12 is welded or riveted to the curtain 11, and the light strips 13 are embedded in the grid gaps. For example, the grid frame divides the curtain into a stable hexagonal cell array, with an LED bead fixed at the center of each cell. It should be noted that the flexible base layer 1 adopts a flexible structure for portability. When not in use, the system can be rolled up into a cylindrical shape for easy storage and carrying.

[0027] Map layer 2 is laid flat on the flexible base layer 1, with a checkerboard grid printed on the side away from the flexible base layer 1. Generally, the checkerboard grid is arranged in a hexagonal grid pattern. The position and number of the checkerboard grid correspond to the position and number of the LED units. For example, map layer 2 is a highly elastic polyester fabric, which is printed with hexagonal grids and terrain information such as mountains, rivers, and roads that are completely aligned with the base layer cells using high-precision inkjet printing technology. Its edges have Velcro or magnetic strips, which can be temporarily fixed to the edge of the base layer to ensure flat alignment.

[0028] Several chess pieces 3 are placed on the chessboard grid and can move on the chessboard grid according to the pusher's instructions; Image acquisition module 4 is used to acquire images of chess pieces and send the images to the control and processing module; wherein, the image acquisition module can be a camera set above the chess piece.

[0029] The control and processing module 5, connected to the light strip 13 and the image acquisition module 4, is used to control the lighting of the LED unit and to identify chess piece information based on the received chess piece image. This control and processing module can control the host computer.

[0030] Preferably, the bottom of the chess piece is provided with a ring magnet, and the chess piece is placed on the map layer by the cooperation of the ring magnet and the grid structure.

[0031] More preferably, such as Figure 3 and Figure 4 As shown, the bottom of the chess piece has a light-transmitting area, and the annular magnet is arranged around the light-transmitting area. For example, the chess piece 3 includes a shell 31, and a miniature model representing a unit can be placed inside the shell 31. A light-transmitting hole 32 is opened at the center of the bottom of the shell 31, and an annular magnet 33 is embedded around the light-transmitting hole 32.

[0032] like Figure 3 As shown, an identification mark is provided inside or on the bottom of the chess piece so that when the chess piece is attached to the chessboard grid, the light emitted by the LED unit can illuminate the identification mark. The identification mark includes at least one of a specific color filter, fluorescent material, or a micro-reflective coded dot matrix. For example, a specific color filter 34 or a micro-reflective sheet with binary dot matrix coding can be provided above the light-transmitting hole 32 inside the chess piece.

[0033] Preferably, the chess piece is provided with a miniature light source, which is triggered to emit light or change its color when the corresponding LED unit is lit.

[0034] In one embodiment, the control and processing module controls the LED units to light up in a scanning manner according to the coordinate sequence of the chessboard grid; The image acquisition module simultaneously captures images of the chess pieces corresponding to the LED unit when the LED unit is lit, in order to extract the image area of ​​the lit chess piece and send the image area of ​​the lit chess piece to the control and processing module.

[0035] In one embodiment, the control and processing module includes an AI recognition unit; The AI ​​recognition unit receives the image area of ​​the illuminated chess piece, identifies the chess piece identification mark based on the image area of ​​the illuminated chess piece, and determines the identity information, type information and status information of the illuminated chess piece based on the chess piece identification mark and a preset mapping relationship.

[0036] In one embodiment, the system further includes a display terminal; The display terminal receives the identity information, type information, and status information of the illuminated chess piece, and calculates the dynamic battlefield situation based on the identity information, type information, and status information of the illuminated chess piece and preset deduction rules.

[0037] The present invention provides an electronic wargaming simulation system based on optical positioning, the specific working process of which is as follows: The player places map layer 2 on the flexible base layer 1 and attaches the chess pieces 3 to map layer 2. During initialization, the control host 5 uses the LED strip controller to quickly scan and light up each LED cell sequentially, while the camera 4 simultaneously captures images. The software on the control host 5 analyzes the images captured each time the LEDs are lit, identifying each cell with a chess piece and the characteristics displayed at its bottom after being illuminated (e.g., red light represents red units, blue light represents blue units, specific codes represent A, etc.), thereby establishing an initial chessboard state database.

[0038] During the simulation, after a piece is moved, the player can trigger a "recognition" command for that piece by clicking on a grid on the software interface of the control unit 5 or by issuing a voice command. The control unit 5 then illuminates the LED of that grid, the camera captures a picture, and the software quickly locates the area of ​​brightness change (i.e., the new piece that has been moved there) by comparing it with the previous frame image, and identifies its characteristics to update the database. Simultaneously, based on wargaming rules, the system can automatically calculate and display the unit's line-of-sight, attack range, and battle results, greatly improving simulation efficiency and immersion.

[0039] The present invention provides an electronic wargaming simulation system based on optical positioning, which has the following technical effects: Fast and accurate recognition: It adopts the "positioning first and then recognition" method. By actively illuminating, the recognition area is greatly reduced, avoiding complex global calculations. The recognition speed and accuracy are high, and it is not affected by top light or chess pieces blocking the view.

[0040] The integration of virtual and real elements is seamless: it retains the feel and intuitiveness of physical chess piece simulation, while simultaneously achieving real-time digitization of the status of all pieces (position, identity, health, etc.), providing a perfect data foundation for AI adjudication, situation analysis, and game review.
