Fig. 2 is the technique of binocular stereoscopic vision principle schematic adopting in the specific embodiment of the invention;
Fig. 3 is that in the specific embodiment of the invention, the technical schematic diagram of inserting method is thrown in court with LED display system and advertisement accurately thereof.
Embodiment
In order to adapt to the demand in market, can automatically intercut rapidly LED display advertisement from the motion tracking camera lens of broadcasting live, picture is represented to on-the-spot broadcasting video pictures, realize global live publicity.The present invention proposes a kind of court LED display system, can automatically identify the football on court, analyze the distance of global LED display of football vertical range, thereby calculating LED picture represents on-the-spot broadcasting and needs the viewing area of intercutting on video, and judgement and automatic commercial breaks picture, the LED advertising of realizing global on-the-spot live game coverage.
This court by LED display system as shown in Figure 1, comprise: the master control computer, LED Video Controller and the intelligent environment controller that are arranged on Master Control Center, and the global field LED display and the web camera that are arranged on court, wherein global LED display comprises a plurality of LED display unit casings, each LED display unit casing is arranged around court, conventionally form a circle, therefore global LED display claims again enclosure screen die.And that described web camera has is a plurality of, according to court actual conditions, to arrange, several LED display unit casings of being separated by are in principle installed a web camera, and such as being separated by, 2 or 3 LED display unit casings are installed a web camera.LED Video Controller is connected with intelligent environment controller with master control computer, also be connected with global LED display on court, realization is controlled the demonstration of global LED display, and web camera uploads to master control computer by network by captured on-the-spot realtime image data.
The advertisement accurately of this court LED display system is thrown in inserting method and is comprised the steps:
S1), gather image: by web camera, obtain court realtime graphic;
S2), analysis image: the vedio data of 2 camera acquisitions that the real-time analysis of master control computer is adjacent, based on characteristics of image, from 2 video images, identify respectively football, and obtain the position of football in image;
S3), calculate the physical location of football: the position calculation according to football in image goes out the physical location of football T-ground;
S4), specific aim throws in advertisement: according to the physical location of football T-ground, determine with the immediate LED display unit casing of football as target casing, and throw in targetedly setting advertisement to this target casing.
Between the present invention and prior art, key difference is that system can identify the football on court automatically, analyzes the position of football distance L ED display screen, and automatically triggers and break for commercialsy near display screen box body football.Because on-the-spot broadcasting 99% camera lens focus is football, thereby can very efficient advertisement picture be presented on live video.And traditional advertisement insertion is all to intercut by artificial button, can not automatically trigger, display speed is slow, can not meet gray demand.The present invention adopts automatic identification technology, can trace into most on-the-spot broadcasting camera lens, can be easily, very flexible, effectively help advertiser automatically the important advertisement of issue to on-the-spot broadcasting video.Reduced manual operation, the picture that has improved system intercuts speed and fail safe.
Wherein, step S2) specifically comprise the steps: again
S21), extract the region, non-meadow in image: in football video image, there are very high stability and unicity in meadow, and the HSV accumulation color histogram by statistical picture, can obtain main color component, i.e. meadow color component easily.The distance of each pixel of computed image and main color, by distance size, judgement extracts region, non-meadow, with black, represents region, non-meadow, generates bianry image.Wherein, black represents region, non-meadow.
S22), cut apart bianry image: utilize shape and the size characteristic of football, analyze football regional location.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/P
2, wherein, A represents the area in region.P represents the girth in region.F value more approaches 1, approaches circle, may be more football.(4) eccentricity, the ratio of region major axis and minor axis dimension.E=D
l/ D
s, D
land D
srepresent respectively the length of region minimum boundary rectangle and wide.Eccentricity is less, and the probability of ball is larger.By form parameter (F) and eccentricity (E), compare, find out the region that 3 (or being less than 3) approach football-shaped most.
S23), abate the noise: use video image, adopt Hough transformation to detect the straight line of removing in court, eliminated the noise that in court, markings produce.
S24), confirm football: consider football around major part be all that ，Dang region, meadow has the color value of 4 points close with main color in 8 neighbor points around, think in this region and comprise football.Use video image, analyze the region of determining step 2 generations 3 (or being less than 3), find out most likely unique region of football.From video image, determine the center in football region, i.e. the image space of football in video image.
Step S3 wherein), calculate the physical location of football, specifically the position in image according to football, adopts 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, and the while to same target photographic images, is then calculated the locus of target from two diverse locations according to triangle relation by object matching.As shown in Figure 2, L, R represent two video cameras in left and right, point O represents football, focal length of camera is f, between video camera, distance is b, and Lo is the center of the image (abbreviation left image) that photographs of left video camera L, and Lx is the imaging on some O on the left side image, Ro is the center of the image (abbreviation right image) that photographs of right video camera R, and Rx is the some O imaging on image on the right.According to triangle relation, can calculate O point and to the vertical range of LR line be
Wherein xL is the abscissa in some Lx on the left side image, and xR is the some Rx abscissa in image on the right, and c is exactly the radius of spheroid.
Step S4), specific aim throws in advertisement as shown in Figure 3, specifically comprise the steps: again
S41), determine target casing: display screen master control computer, according to the distance d of football vertical range casing plane, is determined vertical corresponding casing numbering (supposing it is N casing);
S42), break for commercialsy: according to d value size and N box location, calculate viewing area realization and intercut.Wherein, viewing area scope is can be self-defining, is generally defaulted as 20 meters of the left and right of N casing.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
