Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.
The present invention carries out point location to the LED display image collected, and judge the LED point line direction that finds and column direction lamp point number whether consistent with the lamp point number of LED display reality, consistent then represent point location correct, inconsistent, represent that point location may be wrong, now show for user's inspection and change point location by the result of the LED display image collected and point location, the errorless rear continuation of point location to be confirmed corrects.
Particularly, a kind of LED display pointwise correction method that one embodiment of the invention proposes comprises the steps:
Step (a): gather LED display image; Such as by be provided with pointwise correction software computing machine control LED display carry out local light or full frame lightening LED lamp point to show image, such as red image, green image, blue image etc., then utilize image capture device such as CCD camera to take to collect required LED display image to the image shown by LED display.
Step (b): point location is carried out to the LED display image collected and the number of lamp point on detect lines direction and column direction.
Step (c): judge that whether the line direction detected is consistent with the number of LED display actual lamp point with the number of lamp point on column direction:
(c1) if the number of lamp point is more than LED display actual lamp point number on the line direction detected and column direction, the columns namely detected or line number are greater than columns or the line number of LED display reality; May be now because surround lighting is too strong, also assign the bright spot that surround lighting is formed as the process of LED point, be also likely that LED display screen body lights mistake (or claiming to beat screen error).The LED display image of point location result and collection shows by correction software, provides preliminary conclusion and possible reason confession user selection, as shown in Figure 1 simultaneously.User finds after checking LED display image: if cause point location mistake due to ambient light interference, enter step (d) and carry out manual calibration point location; If on LED display image lamp point really and detect consistent, but point location has more a few row or several row, then must be to beat screen error, now needs to stop current correction flow process, check display screen configuration ensure to beat shield errorless after restart correction; If cause point location mistake because moment veiling glare affects, then can select Resurvey present image.
(c2) if the number of lamp point is less than the number of LED display actual lamp point and the line number detected or columns are less than actual line number or columns on the line direction detected and column direction, as shown in Figure 2, may be now that LED display exists the region (bound edge) that is blocked, it may be point location mistake, or beat screen error, if user selects to there is bound edge, then jump to step (e) and carry out bound edge detection, if selected element Wrong localization, jump to step (d) and carry out manual calibration point location, if select current mistake not affect correction, directly jump to step (f), user also can select termination current correction, solve after shield portions or check display screen configuration ensure to beat shield errorless after restart correction, or Resurvey present image.
(c3) if the number of lamp point is less than display screen actual lamp point number but the line number detected and columns are equal with columns with the line number of display screen reality respectively on the line direction detected and column direction, namely there is dead lamp (without LED point in point location frame), if dead lamp ratio is less than or equal to default permission dead lamp ratio (dead lamp rate), directly jump to step (f), if dead lamp ratio is greater than the dead lamp ratio of default permission, possible point location is correct but LED display inherently exists so many dead lamps, also possibility point location mistake, as shown in Figure 3, demonstrate LED display image and judge it is the point location frame of dead lamp position, if the dead lamp position consistency of the dead lamp position at point location frame place and LED display itself, then select normal dead lamp, now can revise the dead lamp ratio of permission, if LED display itself there is no multiple dead lamp, it is then point location mistake/unsuccessfully cause dead lamp to increase, jump to step (d) and carry out manual calibration point location, user also can select Resurvey present image.
(c4) if the number of lamp point equals the number of LED display actual lamp point on the line direction detected and column direction, directly step (f) is jumped to.
Summarize it, can find from sub-step (c1), (c2) and (c3), when the number of lamp point on the line direction detected and column direction and the number of LED display actual lamp point inconsistent, correction software provides following several processing mode options for user to select:
1) manual calibration point location is carried out, " point location mistake, people's function calibration point is located " option shown in " there is stray light; manual calibration point location " option such as shown in corresponding diagram 1, Fig. 2, " point location unsuccessfully the causes dead lamp to increase " option etc. shown in Fig. 3;
2) pointwise correction is started after again playing screen, " there is bound edge, the need to detect " option shown in such as, " point location has more a few row or several row " option shown in corresponding diagram 1, Fig. 2 and " stop correcting, again attempt " option etc.;
3) Resurvey present image, such as, " Resurvey present image " option shown in corresponding diagram 1, " Resurvey present image " option shown in Fig. 2, " Resurvey present image " option etc. shown in Fig. 3;
4) directly current point positioning result is used, such as, " current mistake does not affect correction, continues " option shown in corresponding diagram 2, " normal dead lamp, the continues to correct " option etc. shown in Fig. 2.
Step (d): manual calibration point location, display LED display image and point location search a direction and point location result, as shown in Figure 4; Can revise and search behind a direction point location again, also manually can drag and search a point location frame of the several point in drift angle place, direction point location (now can revise search a direction also can not revise search a direction) again to tram, as shown in Figure 5, the point location frame in the upper right corner is the point location frame dragged, if manually dragging point location frame drags wrong local because of carelessness, can locate by return contact, get back to the position before dragging, after point location to be confirmed is correct, select to continue correction and jump to step (f), user also can stop correcting process.
Step (e): if desired bound edge detects, then carry out step: when the line number detected is less than the actual line number of LED display, then may there is bound edge above or below LED display; When the columns detected is less than the actual columns of LED display, then may there is bound edge on the left side of LED display or the right.According to testing result, respectively the part that may there is bound edge is judged, judgment mode can adopt the method as Fig. 6, to detect top bound edge, if the line number of bound edge is 5, then show 6 portable lighter points up, LED display just can be seen and have lamp point to light, suppose that the actual line number of display screen is 128, the line number detected is 108, and namely line number decreases 10 row, then top bound edge mostly is 10 row most, successively light from 1 lamp o'clock to 11 portable lighter points above software control LED display, as long as when client's input sees having lamp to light.After bound edge detects, software according to the bound edge number arranged, from step (a), is divided into target to restart correction with non-packet edge automatically.It is worth mentioning that, when carrying out bound edge detection, directly can fill in the number of bound edge, also can detect in multiple orientation simultaneously.
Step (f): the original bright chroma information extracting each LED lamp point according to point location result.
Step (g): the bright chroma desired value according to the original bright chroma information extracted and setting calculates the correction coefficient of each LED lamp point and is uploaded to hardware, is also namely typically uploaded to the control card in the control system of LED display.
See Fig. 7, it is the module diagram of a kind of LED display pointwise correction location device of the embodiment of the present invention.As shown in Figure 7, the LED display pointwise correction location device of the present embodiment comprises: point location and detection module 70, judge module 72, result display module 74, bright chroma information extraction modules 76, manual calibration point location module 78 and preferred bound edge detection module 79.
Wherein, point location and detection module 70 are for carrying out point location to the LED display image collected and the number of lamp point on detect lines direction and column direction.Whether judge module 72 is consistent with the number of LED display actual lamp point for judging the number of line direction and the lamp point on column direction detected.If result display module 74 for judged result be on the line direction and column direction that detect the number of lamp point and the number of LED display actual lamp point inconsistent, show described LED display image and point location result and check for user and show multiple processing mode options for user and select to carry out subsequent treatment obtaining object location result.Bright chroma information extraction modules 76 is for extracting the original bright chroma information of LED point according to object location result.Manual calibration point location module 78 is for carrying out manual calibration to obtain object location result based on man-machine interaction mode to the point location result that described result display module shows.Bound edge detection module 79 for select user in described multiple processing mode option again beating screen after start pointwise correction a kind of situation under, bound edge detection is carried out to LED display.Concrete function details as modules 70-79 refers to aforesaid step (b) to step (f), does not repeat them here.
