Embodiment
Below in conjunction with each embodiment shown in the drawings, the present invention is described in detail; but should be noted that; these embodiments are not limitation of the present invention; those of ordinary skills are according to these embodiment institute work energy, method or structural equivalent transformation or alternative, within all belonging to protection scope of the present invention.
It should be noted that, the not generally definition to wide-angle and long Jiao in photography industry of " wide-angle lens " defined herein and " telephoto lens ", in the present invention, the definition of two camera lenses is relative, the camera lens of shorter that camera lens of focal length is divided into " wide-angle lens ", by another focal length the camera lens of that long camera lens be divided into " telephoto lens ".
As shown in Figure 1, for the wide-angle of the present embodiment schematic perspective view with long burnt double mode automatic tracing recorded broadcast equipment 100, it comprises: pedestal 10, be supported in described pedestal 10 erecting frame 11, connect described erecting frame 11 main body 12, be arranged at video acquisition device 14 and identification module 13 in described main body 12.In present embodiment, video acquisition device 14 is preferably high definition 1080P video camera.
Above-mentioned automatic tracing recorded broadcast equipment 100 also comprises tracker (not shown).Described tracker is carried by the personnel of collected video information, and it can be embedded on described body 12 by described identification module 13, the image of tracker is identified, and determined its position.Described identification module 13 comprises wide-angle lens 131 and telephoto lens 132, and wherein wide-angle lens 131 is applicable to searching close-in target, and telephoto lens 132 is applicable to searching distant object.
By wide-angle lens 131, can search infrared light supply set on target object.Because wide-angle lens 131 is applicable to closely taking, so when close together between lecturer position and camera lens, wide-angle lens 131 just can capture the aiming pip of the infrared light supply in image source, then by video acquisition device 14, makes a video recording, and so photographic effect is more excellent.
Further, if wide-angle lens 131 finds described infrared light supply, by video acquisition device 14, take; If wide-angle lens 131 does not find described infrared light supply, switch to telephoto lens 132 and search described infrared light supply.Because telephoto lens 131 is applicable to remote target to carry out Search and Orientation, so when distant between lecturer position and camera lens, telephoto lens 131 just can capture the aiming pip of the infrared light supply in image source, then makes a video recording.By providing two-path video for identification module 13, one tunnel is the video that adopts wide-angle lens 131, another road adopts the video of telephoto lens 132, according to the current position that is identified target of the judgement of the size intelligence of the target object recognizing, be closely or at a distance, if closely identify with regard to calling the video of wide-angle lens 131, if identify with regard to calling the video of telephoto lens 132 at a distance.No matter be identified target, be closely or at a distance, the recognition performance of recognition system can reach optimum condition like this.
In order to realize the function of the automatically track target object of above-mentioned automatic tracing video recording equipment 100, in the present invention, the above-mentioned tracker of being worn by speaker sends the infrared light supply that a kind of wavelength is 740nm, identification module 13 can be identified infrared light supply, thereby determine lecturer's position, and when lecturer moves, send corresponding control command and come rotating camera to carry out track up.
Particularly, before wide-angle lens 131 and telephoto lens 132, install infrared fileter (not shown) additional, and see through the image source of infrared fileter imageable target object.Described infrared fileter is 740nm narrow band pass filter, by after filtering, on the image obtaining at the camera of wide-angle lens 131 and telephoto lens 132, just only have infrared light supply imaging, that is to say, except infrared light supply imaging is white, the picture of other objects is black.But this is perfect condition, in actual conditions, because the infrared light composition in sunlight is also very abundant, thus at sun-drenched weather, in the image source that camera becomes, still there is many gray areas, or even white bright spot (brightness is lower).Therefore, in the present invention, need the aiming pip that produces by identifying real infrared light supply, could realize the object of track up.
In embodiment preferably, search the highest luminous point of brightness degree in image source, and the luminous point of area maximum in described luminous point is defined as to aiming pip.After the luminous point of system by all existence on traversing graph image source, can divide the affiliated brightness degree of each luminous point, because the bright spot grade of infrared light spot is highest ranking in all luminous points, so first need to pick out the luminous point of highest ranking, moreover, the aiming pip that infrared light supply produces is also area maximum (than the infrared light in sunlight), therefore, be not difficult to find aiming pip position.
Meanwhile, record the coordinate that described aiming pip is arranged in the pick-up lens of wide-angle lens 131 and telephoto lens 132; Preferably, speaker is worn on loins by the tracker of described transmitting infrared light, thus at aiming pip during the middle position in pick-up lens, record coordinate this moment, thus reach best photographic effect.
Aiming pip described in automatic adjustment camera Attitude Tracking, to guarantee that the coordinate of described aiming pip remains in the default coordinate interval of described pick-up lens.Wherein, coordinate interval can be set as: coordinate figure recorded above is benchmark, its horizontal ordinate and ordinate be as the intermediate value in coordinate interval, such as, suppose that recorded coordinate figure is (x, y), the horizontal ordinate fluctuation range in that coordinate interval is x-a ~ x+a, and the ordinate fluctuation range in coordinate interval is y-b ~ y+b, wherein, a, the value of b can be set as required.In other words, when speaker walks about, if going out the current coordinate (horizontal ordinate or ordinate) of infrared light spot, system identification exceeds default fluctuation range, system is sent and is horizontally rotated or the control signal of vertical rotary, thereby the coordinate that keeps described aiming pip remains in the default coordinate interval of described pick-up lens, arrive target following shoot function.
Cooperation is with reference to shown in Fig. 2, Fig. 3, and Fig. 2 is wide-angle and the vertical view of growing burnt double mode automatic tracing recorded broadcast equipment 100 in present embodiment, and Fig. 3 is wide-angle shown in Fig. 2 and the partial sectional view of growing the A-A direction of burnt double mode automatic tracing recorded broadcast equipment 100.
