Accompanying drawing explanation
Fig. 1 is the block diagram of system of court LED display screen system in the specific embodiment of the invention；
Fig. 2 is the technique of binocular stereoscopic vision principle schematic employed in the specific embodiment of the invention；
Fig. 3 is that in the specific embodiment of the invention, court LED display screen system and advertisement accurately input thereof are intercutted
The technical schematic diagram of method.
Detailed description of the invention
In order to adapt to the demand in market, can the most automatically intercut LED from motion tracking on-the-spot broadcasting camera lens
Display screen advertisement, is presented to live video picture by picture, it is achieved global live publicity.The present invention
Propose a kind of court LED display screen system, can automatically identify the football on court, analyze football
The distance of vertical dimension global field LED display, thus calculate LED picture and be presented to on-the-spot broadcasting and regard
The viewing area intercutted, and the picture that judges and automatically break for commercialsy is needed, it is achieved the on-the-spot race in the whole world on frequency
Live LED advertising.
This court LED display screen system is as it is shown in figure 1, include: be arranged on the master control electricity of Master Control Center
Brain, LED video controller and intelligent environment controller, and the global field LED being arranged on court shows
Screen and web camera, the most global field LED display includes multiple LED display unit casing, respectively
LED display unit casing around court arrange, generally form a circle, thus global field LED display also known as
Enclosure screen die.And described web camera has multiple, arrange according to court practical situation, be separated by several in principle
A web camera installed by individual LED display unit casing, is such as separated by 2 or 3 LED and shows
Unit box installs a web camera.LED video controller controls with main control computer and intelligent environment
Device connects, and is also connected with the global field LED display on court, it is achieved to global field LED display
Display controls, and it is electric that captured on-the-spot realtime image data is uploaded to master control by network by web camera
Brain.
The advertisement accurately of this court LED display screen system is thrown in inserting method and is comprised the steps:
S1), image is gathered: obtain court real time imaging by web camera；
S2), image is analyzed: main control computer analyzes the video image of adjacent 2 camera acquisition in real time
Data, identify football from 2 video images respectively based on characteristics of image, and obtain football at image
In position；
S3) physical location of football, is calculated: go out football at ball according to football position calculation in the picture
Physical location in Chang；
S4), specific aim throws in advertisement: according to the physical location of football T-ground, determine with football
Close LED display unit casing is as target casing, and throws in targetedly to this target casing and set
Determine advertisement.
Between the present invention and prior art, key difference is the football that system can identify on court automatically,
Analyze the position of football distance LED display, and automatically trigger the display broken for commercialsy near football
On screen casing.Owing to the camera lens focus of on-the-spot broadcasting 99% is football, such that it is able to the most efficient by wide
Accuse picture to be presented on live video.And traditional advertisement insertion is all that manually button intercuts, it is impossible to from
Dynamic triggering, display speed is slow, it is impossible to meet gray demand.The present invention uses automatic identification technology,
Most on-the-spot broadcasting camera lens can be traced into, can easily, help the most flexible, effectively wide
Accuse business and automatically issue important advertisement to live video.Decrease manual operation, improve the picture of system
Speed and safety are intercutted in face.
Wherein, step S2) specifically include again following steps:
S21) region, non-grass ground, extracted in image: owing to, in football video image, meadow has the highest
Stability and unicity, by the HSV accumulation color histogram of statistical picture, can obtain easily
To domain color component, i.e. meadow color component.Calculate the distance of each pixel of image and domain color, logical
Cross distance size, it is judged that extract region, non-grass ground, represent region, non-grass ground with black, generate binary map
Picture.Wherein, black represents region, non-grass ground.
S22), segmentation bianry image: utilize the shapes and sizes feature of football, analyze position, football region
Put.Specific features has: the size of the major axis of (1) cut zone；(2) area of cut zone；(3)
Form parameter F=4 π A/P2, wherein, A represents the area in region.P represents the girth in region.F value is more
Close to 1, closer to circle, the most more it is probably football.(4) eccentricity, region major axis and minor axis dimension it
Ratio.E=DL/DS, DLAnd DSRepresent length and the width of region minimum boundary rectangle respectively.Eccentricity is the least,
The probability of ball is the biggest.Compared by form parameter (F) and eccentricity (E), find out 3 (or less than 3
Individual) closest to the region of football-shaped.
S23), abate the noise: use video image, use Hough transformation detection to remove the straight line in court,
Eliminate the noise that in court, markings produce.
S24), football is confirmed: be all meadow in view of major part around football, 8 neighbours around region
The color value having 4 points near point is close with domain color, then it is assumed that comprise football in this region.Use regards
Frequently image, analyzes the region of 3 (or less than 3) judging that step 2 produces, finds out most likely
The sole zone of football.From video image, determining the center in football region, i.e. football is at video
Image space in image.
Wherein step S3), calculate the physical location of football, specifically according to football in the picture
Position, uses technique of binocular stereoscopic vision to calculate the physical location of football T-ground.
Technique of binocular stereoscopic vision is the eyes with two video camera simulation people, simultaneously from two diverse locations
Same target is shot image, is then calculated the space bit of target by object matching according to triangle relation
Put.As in figure 2 it is shown, L, R represent that two video cameras in left and right, some O represent football, focal length of camera
For f, the spacing of video camera be b, Lo be the image (abbreviation left image) that left video camera L photographs
Center, Lx is O imaging in left image, Ro be right video camera R photograph image (letter
Claim right image) center, Rx is the imaging on O image on the right.According to triangle relation, permissible
Calculating O point to the vertical dimension of LR line is
Wherein xL is Lx abscissa in left image, and xR is the horizontal stroke in Rx image on the right
Coordinate, c is exactly the radius of spheroid.
Step S4), specific aim throw in advertisement as it is shown on figure 3, specifically include again following steps:
S41), determine target casing: display screen main control computer according to football vertical dimension casing plane away from
From d, determine vertical corresponding casing numbering (assuming it is N casing)；
S42), break for commercialsy: according to d value size and N box location, calculate viewing area and realize inserting
Broadcast.Wherein, viewing area scope is can be self-defining, is typically defaulted as 20 meters, the left and right of N casing.
Above content is to combine concrete preferred implementation further description made for the present invention,
It cannot be assumed that the present invention be embodied as be confined to these explanations.For the technical field of the invention
For those of ordinary skill, without departing from the inventive concept of the premise, it is also possible to make and some simply pushing away
Drill or replace, all should be considered as belonging to protection scope of the present invention.
