Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained all other without creative efforts
Embodiment shall fall within the protection scope of the present invention.
Fig. 1 is the prize drawing equipment three dimensional structure diagram of the embodiment of the present invention；Fig. 3 is the prize drawing equipment of the embodiment of the present invention
For connection diagram an embodiment of the present invention provides a kind of prize drawing equipment, which includes filming apparatus 1, image procossing dress
Set 3, face identification device 4, prize drawing device 5, image stacking apparatus 2 and display device 7.
It should be noted that the image captured by filming apparatus of the embodiment of the present invention 1 is dynamic, but video recording is substantially
It is made of the static image of multiframe, so the processing procedure of its actually static image of the processing procedure of video recording, the embodiment of the present invention
Middle most contents are introduced by taking the processing of static image as an example, with the clearer operational process to the prize drawing equipment and set
Standby structure is explained.
Fig. 2 is the prize drawing equipment vertical view of the embodiment of the present invention.Filming apparatus 1 is used to obtain the real-time pictures at scene, packet
One or more capture apparatus are included, capture apparatus can specifically photograph for video recorder, high speed camera etc. and equipment of making video recording, in order to
Better region overlay effect is obtained, the unmanned plane equipped with capture apparatus can also be increased and carry out high-altitude shooting.It should be noted that
, in specific implementation, since every the same capture apparatus all there is certain coverage to limit, for filming apparatus 1
All audience areas of space for activities can be completely covered, the coverage of size and capture apparatus for space for activities can be with
Arrangement one is simutaneously arranged multiple photographic equipments to realize all standing of space for activities, ensures that the head portrait of all spectators includes
In the coverage of filming apparatus 1.
Image processing apparatus 3 is used to handle the image captured by the filming apparatus 1, in general, image processing apparatus 3 has
The image input interface and image output interface for having multichannel, are internally provided with the image processing hardware optimized for image procossing
System, specifically, the image input interface incoming image processing hardware system of the multichannel can pass through multichannel PCI-E video acquisitions
Card is realized；Image output interface can be used RJ45 interfaces and carry out speedy carding process；Image processing hardware system include image processor,
The physical computing card of mainboard and multichannel, image processor and physical computing card are installed on mainboard, and multichannel physical computing can be used
Card accelerates for image calculation processing；In image processing hardware system, including image integration module and image compression module.
Each capture apparatus in filming apparatus 1 is connected on the image input interface of the image processing apparatus 3,
It is first respectively connected to image integration module per image input interface all the way；Since the optical texture of every the same capture apparatus is former
Cause, especially during this high speed imaging of the embodiment of the present invention, being ultimately imaged the range other than focus can exist
A part obscures, and in order to which the identification of subsequent head portrait can be carried out accurately, usually only retains every the same capture apparatus clear area
Image.For the design parameter per capture apparatus all the way, usually the parameter of image integration module is adjusted in advance, it is right
Certain for capture apparatus, only retains the clear image information in road some region of capture apparatus, specific region is optional all the way
Square area is selected, parameter is by the top left corner pixel point coordinates of square area and the length of square area pixel and wide group
At.Specifically, assuming that the imaging region of single capture apparatus is areas imaging 102, squared region is chosen from its clear image 103
Domain clear image 103 is used for spliced panoramic clear image.It is synchronous, image integration module to all image informations for reaching it into
Row processing, obtains the clear image information per capture apparatus all the way, and by all clear image information according to setting sequence into
Row splicing, prevents non-conterminous image mosaic together, and mistake occurs.
It should be noted that sequence signified in above being spliced all clear image information according to the sequence of setting
It is that the capture apparatus connected according to multiway images input interface is set.Not due to the region that capture apparatus is shot every equally
Together, it in specific implementation, is attached respectively from different image input interfaces per capture apparatus all the way, in order to make the clear of extraction
Sequence of the clear image information when integrating is consistent with actual conditions, the shooting area according to capture apparatus is needed, to it in image
It integrates mould position in the block to be adjusted, keeps image integration mould in the block per the clear image information extracted all the way and its actual bit
Set it is identical, to keep the consistency of figure.
Specifically, the region of the first filming apparatus 105 shooting is first area 107, the area of the second filming apparatus 106 shooting
Domain is 108, and in order to keep its splicing correct, it is defeated no matter which image the first filming apparatus 105 and the second filming apparatus 106 access
In incoming interface, the position of first area 107 and second area 108 should be adjusted to position shown in Fig. 2 in image integration module.

Number circuit and circuit for generating random number, for carrying out face according to prize drawing parameter from the face identified in face identification device 4
Prize drawing.Specifically, counting of the counting circuit by face location information, is transferred to circuit for generating random number by sum, then exists
Circuit for generating random number carries out random number extraction in Serial Number Range, and the random number pass ultimately generated is superimposed to image and is filled
Set 2.
Image stacking apparatus 2 is connected to image processing apparatus 3, face identification device 4, prize drawing device 5.First, shadow
As stacking apparatus 2 receives the face location of the complete sharp image and face identification device 4 of image processing apparatus 3, complete clear
On the basis of clear image, face frame is generated to show face position, and the figure that will be superimposed with face frame according to face location
As in output to display device 7.Then the corresponding head portrait of random number extraction transmitted by prize drawing device 5 is independently by the face
In output to display device 7, to announce drawing outcomes.
Above-described independence exports the face drawn to the embodiment in display device 7, can be individually extraction
The image of face location is exported to display device 7, can also be shielded the image other than face location, with same color
Background covered.
Display device 7 is used to show the generation content of image stacking apparatus 2, can be that the images such as display screen, projection are shown
Equipment.
It should be noted that the image processing apparatus 3 of the embodiment of the present invention, face identification device 4, prize drawing device 5, image
