Embodiment
Here will be described exemplary embodiment in detail, its sample table shows in the accompanying drawings.When description below relates to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawing represents same or analogous key element.Embodiment described in following exemplary embodiment does not represent all embodiments consistent with the disclosure.On the contrary, they only with as in appended claims describe in detail, the example of apparatus and method that aspects more of the present disclosure are consistent.
Because concatenation unit each in mosaic screen cannot accomplish zero piece splicing, cause spliced image cannot be excessively smooth, entire image cannot be made to reach overall consistent.As shown in Figure 1, Fig. 1 is the schematic diagram of mosaic screen exploded view picture in correlation technique.
In order to avoid accomplishing that due to concatenation unit each in mosaic screen zero piece splicing causes spliced image cannot be excessively smooth in stitching portion, entire image cannot be made to reach overall consistent situation, the disclosure provides a kind of piece compensation method of mosaic screen, as shown in Figure 2 A, Fig. 2 A is the process flow diagram of the piece compensation method of a kind of mosaic screen of the disclosure according to an exemplary embodiment, and the method comprises the following steps 201 to step 204:
In step 201, the target physical piece value of concatenation unit in mosaic screen is obtained.
In step 202., target splicing quantity and the target position information of concatenation unit in described mosaic screen in described mosaic screen is obtained.
In step 203, described target physical piece value, described target splicing quantity and target stretching information corresponding to described target position information is determined according to the relation table prestored, described relation table records physics piece value, splicing quantity, incidence relation between positional information and stretching information, the range information that described target stretching information is physics piece for compensating described concatenation unit and stretches to image in described concatenation unit.
In step 204, according to described target stretching information, image in described concatenation unit is stretched.
In disclosure embodiment, by obtaining the target physical piece value of concatenation unit in mosaic screen, target splicing quantity and the target position information of concatenation unit in mosaic screen, thus according to obtained information and the relation table determination target stretching information that prestores, according to target stretching information, image in concatenation unit is stretched, to make the image in the image in this concatenation unit and contiguous concatenation unit excessively smooth in stitching portion, the image realizing the splicing of each concatenation unit reaches overall consistent, and because robotization realizes image stretch, thus improve piece compensation efficiency.
Disclosure embodiment can perform in each concatenation unit of mosaic screen, is stretched separately, thus realize the consistance of whole image by each concatenation unit to the image that self receives.
Disclosure embodiment also can perform in the central processing unit of mosaic screen, is undertaken unifying controlling and adjustment, thus realize the consistance of whole image by central processing unit.
About step 201, concatenation unit can be single display screen, can be called again splicing single screen or display unit.Concatenation unit can be the display screen with physics piece, such as, can be LCDs.
Multiple concatenation unit can be spliced into mosaic screen, and mosaic screen can be called combination again.Such as, 4 concatenation units can be spliced into the mosaic screen of 2*2, and 9 concatenation units can be spliced into the mosaic screen of 3*3.
In master driver, can the screen build number of record concatenation unit and corresponding parameter information, such as, corresponding parameter information can comprise size, brightness, piece, such as Samsung 46 cun, low bright, 5.7mm physics piece etc.The disclosure can obtain the target physical piece value of concatenation unit from parameter information.Be understandable that, target physical piece value and physics piece value, in order to distinguish the physics piece value of other concatenation units, and by the piece value called after target physical splicing value of current concatenation unit.
About step 202, target splicing quantity is concatenation unit quantity in mosaic screen, and such as splicing quantity can be 2*2,4*4 etc.The target position information of concatenation unit in mosaic screen can be a number information, also can be a ranks coordinate information, can also be two-dimensional coordinate information, as long as can the position of unique identification concatenation unit in mosaic screen.
Be described for 2*2 mosaic screen, when representing with ranks coordinate, the positional information of the concatenation unit of the first row first row can be [1,1], the positional information of the concatenation unit of the first row secondary series can be [1,2], the positional information of the concatenation unit of the second row first row can be [2,1], the positional information of the concatenation unit of the second row secondary series can be [2,2].Be understandable that, first digit represents that concatenation unit is expert at, and second digit represents concatenation unit column.When representing with two-dimensional coordinate, the positional information of the concatenation unit of the first row first row can be (1,1), the positional information of the concatenation unit of the first row secondary series can be (2,1), the positional information of the concatenation unit of the second row first row can be (1,2), the positional information of the concatenation unit of the second row secondary series can be (2,2).
In an optional implementation, in mosaic screen, the quantity of concatenation unit can be fixing, such as, be fixed as 2*2 mosaic screen, is and for example fixed as 4*4 mosaic screen etc.Based on this, the positional information of concatenation unit in mosaic screen is fixing, can be stored in concatenation unit by the positional information of concatenation unit, when needing to calculate target physical piece value, from concatenation unit, directly obtains target position information at every turn.
In another optional implementation, the quantity of the concatenation unit in mosaic screen can be change.Such as, the mosaic screen of a 4*4, only needs to use 4 concatenation units in mosaic screen in some scenarios, then the mosaic screen of these 4 concatenation unit composition 2*2, the mosaic screen that namely composition one is new.
Because in mosaic screen, concatenation unit number may change, then the positional information of concatenation unit in mosaic screen may change, therefore, can receive the configuration information of described mosaic screen, described configuration information comprises target splicing quantity and the target position information of concatenation unit in described mosaic screen.
Wherein, configuration information can be that user is sent to the information comprising target splicing quantity and the target position information of concatenation unit in mosaic screen of actuating station of the present invention by control end.Such as, by the mode of infrared transmission, the configuration information of mosaic screen can be sent to actuating station of the present invention, as the configuration information of mosaic screen is sent to actuating station of the present invention by the mode by telepilot; The configuration information of mosaic screen is sent to actuating station of the present invention by the mode that can also be sent by serial ports, as the configuration information of mosaic screen is sent to actuating station of the present invention etc. by the mode by client software.When actuating station of the present invention is concatenation unit, then configuration information can be sent in each concatenation unit, then not only there is the physics piece value of this concatenation unit in each concatenation unit, also obtain the target splicing quantity of mosaic screen, and the positional information of this concatenation unit in mosaic screen.
As seen from the above-described embodiment, target splicing quantity and the target position information of concatenation unit in mosaic screen can be obtained in time by the mode of the configuration information receiving mosaic screen, thus according to target physical piece value, target splicing quantity and target position information determination target stretching information, realize stretching to the image in concatenation unit according to the target stretching information determined in time when splicing quantity or change occurs positional information, realize rapid adjustment, reach the consistance of entire image in mosaic screen, and regulated efficiency is high.
Be understandable that, step 201 and step 202 are all obtaining information steps, can not have sequencing.
About step 203, target stretching information is the target stretching information that described concatenation unit is corresponding, i.e. the target stretching information of image in concatenation unit.Target stretching information is physics piece in order to compensate concatenation unit and the range information stretched to image in concatenation unit.Distance can be weighed with units such as centimetre, millimeters, and in a preferred implementation, distance can be that unit is weighed by pixel, and such as level stretches left the distance of 5 pixels.Take pixel as unit, can draw efficiency be improved.
Wherein, described target stretching information comprises target draw direction and target tension values.Draw direction can be row left direction, row right direction, row upward direction, row in downward direction, draw direction also can be upper left diagonal, diagonal down-left line direction, upper right diagonal, lower-right diagonal position line direction.Wherein, row and column is relative mosaic screen, i.e. the row and column of mosaic screen.Because diagonal can be divided into line direction component and column direction component, diagonal is not repeated at this.
When mosaic screen horizontal positioned, row left direction can be horizontal left direction, row right direction can be horizontal right direction, row upward direction can be that direction, row can be in downward direction vertical downward direction vertically upward.
In addition, the disclosure can be also initial point with the mosaic screen upper right corner, with the behavior transverse axis of mosaic screen, with the row of mosaic screen for the longitudinal axis makes two-dimensional coordinate system, as shown in Figure 2 B, Fig. 2 B is a kind of mosaic screen schematic diagram of the disclosure according to an exemplary embodiment.The mosaic screen that this A, B, C, D tetra-concatenation units are spliced sets up two-dimensional coordinate system, then row left direction can be transverse axis negative direction, row right direction can be transverse axis positive dirction, row upward direction can be longitudinal axis negative direction, row can be in downward direction longitudinal axis positive dirctions.
In order to promote draw efficiency, draw direction only can be limited to this concatenation unit direction adjacent with other concatenation units, such as, in the mosaic screen shown in Fig. 2 B, in concatenation unit A, the target stretching information of image comprises the tension values of horizontal right direction and the tension values of vertical downward direction, other directions do not stretch, or the tension values in other directions is zero.
For relation table, relation table can be the table prestored.The mode obtaining relation table has a variety of, such as, can download relation table from cloud server.The corresponding relation that cloud server can be uploaded according to different user upgrades relation table, and what store in guarantee cloud server is best mapping table.The disclosure obtains relation table from cloud server, thus can improve the follow-up accuracy determining target stretching information.
And for example, each data message stretched is recorded in historical data base, data message comprises physics piece value, splicing quantity, positional information, stretching information and the evaluation information for bandwagon effect, regularly can determine the incidence relation between optimum physics piece value, splicing quantity, positional information, stretching information according to evaluation information, production Methods table.
And for example, the physics piece value of concatenation unit in mosaic screen can be obtained, obtain in mosaic screen and splice quantity and the positional information of each concatenation unit in mosaic screen, receive the debug command to image in each concatenation unit, and record the stretching information of image in debug results, according to the relation production Methods table of physics piece value, splicing quantity, positional information and stretching information.Which can record image effect in debug process preferably time corresponding stretching information, and set up the relation table of physics piece value, splicing quantity, positional information and stretching information.
Be understandable that, relation table can also be determined by other means, and this is no longer going to repeat them.
After determining relation table, relation table can be stored in actuating station of the present invention.When actuating station of the present invention is concatenation unit, each concatenation unit only need record the relation table relevant to self, such as, when the number change of concatenation unit in mosaic screen, then the concatenation unit of the first row first row only needs the target physical piece value of minute book unit, the incidence relation of target splicing quantity, target position information and target stretching information.
In an optional implementation, described target stretching information comprises target draw direction and target tension values.
A target draw direction and target tension values is at least comprised in the target stretching information that each concatenation unit is corresponding.As shown in Figure 2 B, in the mosaic screen of the 2*2 of A, B, C, D tetra-concatenation unit compositions, concatenation unit A is adjacent with concatenation unit B, and the target stretching information that concatenation unit A is corresponding comprises the first tension values stretched and the second tension values stretched to the right downwards; The target stretching information that concatenation unit B is corresponding comprises the 3rd tension values stretched and the 4th tension values stretched left downwards.Visible, then the second tension values is identical with the 4th tension values.
About step 204, after determining target stretching information, can stretch to every two field picture that concatenation unit receives according to this target stretching information.Wherein, concrete stretching algorithm can adopt the stretching algorithm in correlation technique, and this is no longer going to repeat them.
In an optional implementation, described target stretching information comprises the first tension values of row left direction, the second tension values of row right direction, the 3rd tension values of row upward direction and row the 4th tension values in downward direction, describedly according to described target stretching information, image in described concatenation unit to be stretched, comprising: image in described concatenation unit is followed left direction and to stretch the distance of a described first tension values pixel; Image in described concatenation unit is followed the distance of the described second tension values pixel of right direction stretching; By the distance of image in described concatenation unit along the described 3rd tension values pixel of row upward direction stretching; By image in described concatenation unit along the distance arranging the described 4th tension values pixel that stretches in downward direction.
Be understandable that, when mosaic screen horizontal positioned, described target stretching information comprises the 4th tension values of the first tension values of horizontal left direction, the 3rd tension values of the second tension values of horizontal right direction, vertically upward direction and vertical downward direction, describedly according to described target stretching information, image in described concatenation unit to be stretched, comprising: by image in described concatenation unit horizontally left direction to stretch the distance of a described first tension values pixel; By image in described concatenation unit horizontally right direction to stretch the distance of a described second tension values pixel; By the distance of image in described concatenation unit along the described 3rd tension values pixel of direction stretching vertically upward; By the distance of image in described concatenation unit along the described 4th tension values pixel of vertical downward direction stretching.
Wherein, stretch the distance of the first tension values/the second tension values/the 3rd tension values/the 4th tension values pixel, namely the distance stretched is the distance of an above-mentioned tension values pixel, can be after stretching image ratio stretch before the many in the stretching direction tension values pixels of image.
Wherein, relation table records physics piece value, splicing quantity, incidence relation between positional information and stretching information.Such as, in 3*3 mosaic screen each physics piece value, incidence relation between positional information and stretching information, and for example, each physics piece value in 4*4 mosaic screen, incidence relation between positional information and stretching information.In an optional implementation, for 2*2 mosaic screen, the wherein several corresponding relations enumerated in relation table are described:
The first corresponding relation: when splicing quantity is 2*2, target physical piece value is 6.7mm, the target stretching information that the concatenation unit of the first row first row is corresponding is (x
-=0, x
+=5, y
+=0, y
-=5) the target stretching information that, the concatenation unit of target position information the first row secondary series is corresponding is (x
-=7, x
+=0, y
+=0, y
