Coincide, be convenient for user use.It should be noted that in the present invention, for ease of description, the change in size of each image
Amount, the size changing amount of overlapping region are only described by taking the size changing amount (width variation) in width direction as an example.
It is (original state), the first projection arrangement 1 and the second projection arrangement under first the ratio of width to height shown in Fig. 3
2 in the airborne of target area (on screen).Under first the ratio of width to height, first projection arrangement 1 and the second projection arrangement 2 tool
There are first resolution (W1*H1), the first resolution to include the first width parameter W1 on first direction F1, and first image
10 have the first home position, which has the second home position, first image 10 and second image 20 tool
Standby overlapping region S3, overlapping region S3 are on first direction F1 there is third width parameter W3, overlapping region S3 to have
Center line DD's ', center line DD ' extends perpendicularly to first direction F1, the i.e. extending direction of center line DD ' and projection
The short transverse F3 of image is parallel.Such as when first projection arrangement 1 and the second projection arrangement 2 are in first the ratio of width to height 16:Under 9 into
When row projection, image resolution size is all W1*H1=1920*1080 pixels, the third width parameter W3 of overlapping region S3
For 80 pixels, wherein W1 indicates that the pixel in width direction (first direction) is 1920 pixels, is in H1 expression short transverses
1080 pixels；When the ratio of width to height of the first projection arrangement 1 and the second projection arrangement 2 is adjusted to 4:When 3, its image resolution at this time
Also correspondence is adjusted to W2*H2=1440*1080 pixels to size, is 1440 pixels wherein in width direction, is in short transverse
1080 pixels, scaling (change width ratio) is W2/W1=1440/1920=0.75 in width direction, short transverse
Size constancy, and what the size of the third width parameter W3 of overlapping region S3 also can be in proportion is adjusted, third width parameter
It is reduced to original 0.75, i.e., is 0.75W3 by W3 variations, 60 pixels is narrowed down to by 80 original pixels.
Wherein, it when control unit 3 receives new instruction, need to be controlled with second the ratio of width to height (different from first the ratio of width to height)
When the projection of the first projection arrangement 1 and the second projection arrangement 2, the control unit 3 first obtain under the conditions of second the ratio of width to height this first
The second resolution of image 10, wherein the second resolution includes the second width parameter W2 and the second height parameter H2, the control
Unit 3 obtains first image 10 according to second width parameter W2, first width parameter W1, third width parameter W3
The third width variation of width variation, overlapping region S3, and according to the width variation of first image 10, the overlapping
The third width variation of region S3, adjust automatically first projection arrangement and the projection to the second projection arrangement, so that in
Under second the ratio of width to height, the regioselectivity of first image and second image changes can correctly splice.Wherein, should
The width variation of first image is not 0 namely change width ratio (W2/W1) when being not equal to 1, and the position of first image becomes
The calculation formula of change amount is：
M=(W1-W2-W3+W2*W3/W1)/2；
Wherein, M is location variation, and W1 is first width parameter, and W2 is second width parameter, and W3 is that the third is wide
Spend parameter.
Wherein, when location variation M be more than 0 when namely W1 be more than W2 when, the control unit 3 control first image to
The amount of first direction movement is M, and it is M which, which controls the amount that second image is translated to second direction,.Work as change in location
When measuring M less than 0 namely when W1 is less than W2, which controls first image and is moved from the first home position to second direction
Dynamic amount is the absolute value of M, and it is M which, which controls the amount that second image is moved from the second home position to first direction,
Absolute value.
In addition, it is necessary to explanation, when the ratio of width to height changes, if the width variation of first image is not 0,
Then the third width parameter of the overlapping region 30 can also change therewith, specially when the change width ratio of the first image=
The change width ratio of W2/W1, overlapping region 30 are also equal to W2/W1, width variation=third width of the overlapping region 30
Parameter-the second width parameters of third width parameter */the first width parameter=W3-W3*W2/W1.
For example, when first the ratio of width to height is 16:9, the resolution sizes of the first image 10 are W1*H1=1920*1080 pixels,
When second the ratio of width to height is 4:3, the resolution sizes of first image 10 of corresponding second the ratio of width to height are W2*H2=1440*1080 pictures
Element, change width ratio=W2/W1=1440/1920=0.75 at this time, the change width ratio of corresponding overlapping region is also etc.
In 0.75, i.e. the width of overlapping region can also become 80*0.75=60 pixels, shorten 20 pixels.Substitute into calculation formula M=
(W1-W1*W2-W1*W3+W2*W3)/2=230 pixels.About 230 pixel of the first image 10 is translated to the directions center line DD ', the
Two images 20 move 230 pixels to the directions center line DD '.
Above-described embodiment goes to illustrate from large to small with the ratio of width to height；In practical application, also there is the ratio of width to height to become
Change the still constant situation of width direction, specifically can refer to and be described below.
If the first projection arrangement 10 and the second projection arrangement 20 of two splicings, initial image size (resolution ratio) are
W1*H1=800*600 pixels, the ratio of width to height 800/600=4:3, then when by the ratio of width to height from 4:3 are switched to 16:When 9, then image
Size becomes W2*H2=800*450 from W1*H1=800*600, thus while the ratio of width to height changes, however the width of image
Size can't change, i.e., width variation is 0, so the position of image need not be adjusted.That is, when the ratio of width to height is by first
The ratio of width to height change and when being second the ratio of width to height, it is first former relative to this if the width variation of first image is zero
Beginning position and second home position, first image and second image are on the target area under second the ratio of width to height
Position remains unchanged.

M=(W1-W2-W3+W2*W3/W1)/2；
Wherein, M is location variation, and W1 is first width parameter, and W2 is second width parameter, and W3 is that the third is wide
Spend parameter.
Further, when location variation M is more than 0, when width becomes smaller namely W1 is more than W2, the control unit 3 control should
The amount that first image is moved to first direction is M, and it is M which, which controls the amount that second image is translated to second direction,.
When location variation M is less than 0, when width becomes larger namely W1 is less than W2, which controls first image from the first original
The amount that beginning position is moved to second direction be M absolute value, the control unit control second image from the second home position to
