Abstract
The utility model provides an image touch positing device based on four cameras. The image touch positing device based on the four cameras comprises four circuit boards, the four cameras and four light filtering strips, wherein at least one row of infrared diodes are welded to each circuit board, the four circuit boards are arranged in a square mode, the four cameras are arranged on the four vertexes of the square formed by the four circuit boards, each light filtering strip is composed of a first U-shaped portion and a second U-shaped portion, the bottom of each first U-shaped portion is combined with the side edge of the corresponding second U-shaped portion, the circuit boards correspond to the light filtering strips in a one-to-one mode, the circuit boards are inlaid in openings of the first U-shaped portions, and the infrared diodes on the circuit boards right face the bottoms of the first U-shaped portions. The image touch positing device based on the four cameras has the advantages that due to the fact that the light filtering strips are arranged right in front of the infrared diodes, light can be transmitted evenly, the touch capturing function of the device can be more stable, and the use effect of the device is improved.
Description
[technical field]
The utility model relates to a kind of video interaction device, particularly a kind of image touch positioning device based on four cameras.
[background technology]
The video interaction device of four cameras of existing employing, it is comprised of four circuit boards, four cameras, a plurality of infrared diodes, four circuit boards are end to end formation one rectangle closed circuit loop in turn, four cameras are for filtering visible ray and can receive infrared light infrared of Same Wavelength, four cameras are embedded on the summit at four angles of the rectangle that four circuit boards form, the consistent wavelength of the infrared light that the wavelength of infrared diode and cam lens can receive, infrared diode is welded on circuit board.The deficiency of existing apparatus is: because infrared diode is luminous, exist central point light strong, the shortcoming that ambient light is weak, there is strong and weak strength distribution in the light that on whole piece circuit board, infrared tube sends, distribution of light is uneven, this just causes camera when catching position, touch point, in the weak local None-identified touch point of light, cause disconnected pen, affect the result of use of device.
Existing solution to the problems described above is the light sending by reflecting strips reflective infrared diode is set, light is uniformly distributed, but the method is easy to reflecting strips width not and reflector space inadequate, the impact such as extraneous light causes the sensitive not or unfavorable condition such as inefficacy once in a while of seizure in addition.
[summary of the invention]
The technical problems to be solved in the utility model, be to provide a kind of image touch positioning device based on four cameras, the light uniform emission that it launches infrared diode by optical filtering bar is set, makes device more stable to the capture function touching, the result of use of lifting gear.
The utility model is achieved in that
Image touch positioning device based on four cameras, comprise four circuit boards and four cameras, described in each, on circuit board, be all welded with at least one row's infrared diode, described four circuit boards are square and arrange, described four cameras are arranged at the summit at four square angles of described four circuit boards formation, described image touch positioning device also comprises four optical filtering bars, described optical filtering bar is comprised of the first U-shaped portion and the second U-shaped portion, the side of the bottom of described the first U-shaped portion and described the second U-shaped portion combines, described circuit board and described optical filtering bar be corresponding setting one by one, described circuit board is embedded in the opening of described the first U-shaped portion and the infrared diode on circuit board over against the bottom of described the first U-shaped portion.
Further, the dual-side of described the first U-shaped portion and close opening part are equipped with a draw-in groove, and the width of described draw-in groove equals the thickness of described circuit board.
The utility model has the advantage of: by optical filtering bar being set in infrared diode dead ahead, make the even transmission of light, make device more stable to the capture function touching, the result of use of lifting gear.
[accompanying drawing explanation]
The utility model is further described with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the sectional view of the utility model optical filtering bar.
Fig. 3 is the combination schematic diagram of the utility model optical filtering bar and circuit board.
Fig. 4 is that the utility model is used constitutional diagram.
[embodiment]
Refer to shown in Fig. 1 to Fig. 3, embodiment of the present utility model is described in detail.
Image touch positioning device based on four cameras, comprise four circuit boards 1, four cameras 2 and four optical filtering bars 3, described in each, on circuit board 1, be all welded with at least one row's infrared diode 4(figure and show a row), described four circuit boards 1 are square and arrange, described four cameras 2 are arranged at the summit at four square angles of described four circuit boards, 1 formation, described optical filtering bar 3 is comprised of the first U-shaped portion 31 and the second U-shaped portion 32, the bottom 311 of described the first U-shaped portion 31 combines with the side 321 of described the second U-shaped portion 32, described circuit board 1 and described optical filtering bar 3 be corresponding setting one by one, described circuit board 1 is embedded in the opening 312 of described the first U-shaped portion 31 and the infrared diode 4 on circuit board 1 over against the bottom 311 of described the first U-shaped portion 31.Behind light transmission the first U-shaped portion 31 bottoms 311 that described infrared diode 4 sends, pass through again another side 322 of described the second U-shaped portion 32, the even transmission of light, solved in prior art and had the problem of bright dim spot because the luminous characteristics of infrared diode 4 own causes touch area, therefore arrange after optical filtering bar 3, the capture function of 2 pairs of touches of camera is more stable, has promoted result of use.
Dual-side and close opening 312 places in described the first U-shaped portion 31 all arrange a draw-in groove 313, and the width of described draw-in groove 313 equals the thickness of described circuit board 1.Described circuit board 1 is stuck in described draw-in groove 313, fixing more firm.
Refer to Fig. 4, the utility model in use, by a frame 6 by blank 5 together with optical filtering bar 3 secure bond.
Principle of work of the present utility model is: it (can be computer that described four cameras are all connected to a processor, also can be the programming devices such as microprocessor), infrared diode on described four circuit boards is lighted by Power supply, in the square region forming at four circuit boards with hand or other objects, touch, by camera, catch contact image, then transfer to processor and process.
The above, it is only the utility model preferred embodiment, therefore can not limit according to this scope that the utility model is implemented, the equivalence of doing according to the utility model the scope of the claims and description changes and modifies, and all should still belong in the scope that the utility model contains.
