geometry alignment if compared with 25% overlap and have the best geometry alignment
accuracy.
[9x5 Curved] alignment will cut the horizontal image into 8 sections and the image in each
section can be independently adjusted. In different output resolutions, there will be different
pixel number in each section: XGA: 1024/8=128, WXGA: 1280/8=160, 1080p: 1920/8=240.
Usually, [9x5 Curved] alignment is enough for most of the curved screen edge blending.
If the overlap area between two adjacent projectors has the same or multiple number as
above, the geometry alignment control points in overlap region will be less. User can increase
or decrease two or three grids (64 or 96 pixels) in overlap area to increase the control points
in overlap region for more accurate alignment between adjacent projectors.
Below figure is an example for [9x5 Curved] alignment in 1024 resolution:
•
25% overlap region:
The adjusting points in projector A & B will be at the same position in
overlap region
If the overlap is 256 pixels (25%) in XGA resolution, total adjusting points in overlap region are 3*5=15.
The adjusting points in projector A & B will be at the same position in overlap region. User will have less
adjustment flexibility. If increasing two grids (64 pixels) to 320 overlap pixels, user can have 30 adjusting
points to get more accurate geometry alignment. It can align the images from two projectors on curved
screen with good quality by remote controller.
- 37.5% overlap region
The adjusting points in projector A & B will be separated in 37.5% overlap region and increase
geometry alignment accuracy.
