Description

Multiple spot light gun control device based on LCD, projector

Technical field

The utility model relates to a kind of light gun control technology, specifically utilizes photoelectricity and computer graphics disposal technology to solve the light gun control device of commercialization and home game machine.

Technical background

Display technology is being brought in constant renewal in recent years; Compare with traditional CRT monitor; LCD because have power saving, volume is little, radiation is little and display screen can be done characteristics such as big; Display device replaces traditional CRT (field scan) class display by LCD display gradually in commercial game machine industry.Because the multiple spot light gun point technique based on CRT monitor of tradition can't be used, therefore be badly in need of the space sighting device that a kind of light gun that can on LCD display, use, a plurality of can use simultaneously on LCD display.

The utility model content

The purpose of the utility model is: provide a kind of that on LCD display, use, realize the device that a plurality of light guns aim at and shoot the target in the game content simultaneously, have with alternative some touch screen functionality of common screen.

The utility model is achieved in that

Be made up of infrared laser transmitter 1, collector 2, display 4, computing machine 3, the infrared laser transmitter is installed in the light gun, and collector 2 is towards display 4, and the camera of collector the inside can be seen full display.Collector 2 is connected with computing machine 3 through USB interface, and light gun then is connected with computing machine 3 through serial ports, and display 4 is connected with computing machine 3 through the VGA video signal cable.

Said collector is made up of collector housing 5, installation base plate 6, CMOS camera module 7,850nm infrared fileter 8, camera lens 9, collector loam cake 10, common optical filter 11,980nm infrared fileter 12;

Said infrared laser transmitter 1 is two; Said collector 2, the camera of built-in two infrared fileters.

Said CMOS camera module 7, it is adjusted with pad fixedly the time, with the axis that guarantees two cameras relative angle is arranged.

During use; The operator aims at the display cocking with light gun, and light gun will produce luminous point on display, and this luminous point can be captured by corresponding camera (being installed in the collector); Camera produces a frame picture when capturing this point; Picture is transferred to computing machine carry out computing, that is to say that computing machine will be responsible for handling the image information that is obtained by collector, just can obtain this coordinate figure on screen; Games Software is corresponding with the foresight of recreation with this coordinate figure, can accomplish the work of light gun control recreation foresight.Because be that wavelength distinct transmit device and optical filter cooperate, therefore two light guns can not produce the phenomenon of interference.

The utility model utilizes photoelectric technology and computer graphics disposal technology, has solved the problem of the space aiming that realizes that on LCD display a plurality of light guns can use simultaneously well.Solving on the sector technical matters, only having Japanese SIGA company that a patented technology is arranged at present, the utility model is compared with the SIGA technical scheme, and it is more accurate to have an aiming, drags foresight and moves smooth more advantage.Like this, player's sensation meeting when experiencing shooting game is truer.This technology is applied in a shooting game " The Battle Of Taierzhuang ".During recreation, the player uses two light guns, gets into the recreation back with light gun aimed fire target, shoots target behind the cocking dead.

Below in conjunction with embodiment of accompanying drawing narration, the utility model is further specified.

The workflow diagram of Fig. 3 the utility model embodiment.

Embodiment

Fig. 1 has shown the structure of present embodiment.The infrared laser transmitter 1 that mainly is respectively 850nm and 980nm by two wavelength (is installed in the rifle; Be called 1P rifle, 2P rifle respectively), collector 2 (built-in two installed respectively 850nm and 980nm infrared fileter camera, be called 1P camera, 2P camera respectively), display 4 (LCD display or projection screen, projection wall), computing machine 3 form.

When mounted, collector 2 towards display 4, and is guaranteed that the camera (i.e. 7+8+9 among the figure) of collector the inside can see full display; Be connected with computing machine through USB interface.Light gun then is connected with computing machine 3 through serial ports; Display 4 is connected with computing machine 3 through the VGA video signal cable.

Fig. 2 has shown the collector structure of present embodiment

This collector mainly is made up of collector housing 5, installation base plate 6, CMOS camera module 7,850nm infrared fileter 8, camera lens 9, collector loam cake 10, common optical filter 11,980nm infrared fileter 12.CMOS camera module 7 usefulness screws are fixed in to be installed on the base plate 6; 850nm infrared fileter 8 and 980nm infrared fileter 12 usefulness special glue are pasted on the camera lens 9, camera lens 9 through fine thread with form 1P camera and 2P camera respectively after CMOS camera module 7 is connected.Two cameras are fixed on the collector housing 5 through the screw shimming.Common optical filter 11 usefulness special glue stick on the collector loam cake 10, and are fixing through screw and collector housing 5 afterwards, form collector 2

The design feature of this collector 2; One of which is: 1P camera has wherein increased 850nm infrared fileter 8 on common CMOS camera module 7, is used for guaranteeing it and when can't see visible light, can only sees the hot spot that the 1P infrared transmitter produces on screen; 2P camera has wherein increased 980nm infrared fileter 12 on common CMOS camera module 7, be used for guaranteeing it and when can't see visible light, can only see the hot spot that the 2P infrared transmitter produces on screen.So just easily when two light guns are simultaneously luminous, each other without interruption.

The another one characteristics of collector 2 are: two same COMS camera modules 7 are distinguished on its software I D address, are used for guaranteeing no matter earlier being connected 1P camera or 2P camera with computing machine, computing machine can be distinguished two cameras.

Simultaneously, fixedly the time, adjusting the axis that guarantees two cameras with pad has relative angle, so just can guarantee that the camera of two parallel installations can be seen the field range that screen is same at CMOS camera module 7.

Fig. 3 is the workflow of present embodiment.

When the player in when recreation, pull the trigger on the light gun, the infrared laser transmitter can be in luminance (step 1).When the player aimed at screen with rifle, light gun can produce infrared light spot (step 2) on the aiming point on the screen, and this luminous point can only be seen (step 3) by the camera that has installed corresponding wavelength filter additional.Camera is seen and can be produced a width of cloth picture by this luminous point (step 4), the characteristics of this pictures are except the position of light gun aiming point produces a white dot, are black.So just can obtain the position coordinates of this bright spot through the way of analyzing gray-scale value; In fact this position coordinates is exactly the position coordinates (step 5) of light gun aiming point on screen; In recreation, give the player visible foresight (step 6) with this coordinate information; Even along with moving of light gun aiming point, the player just can see the servo-actuated (step 7) of the foresight of its control.The random aiming and the control (step 8) of player alignment star have been accomplished through this process.
