The DCP is a 2U rack mount box suitable for performing geometric corrections and
uniform edge blending in multi-projector applications.
The unit can process up to six single link DVI digital channels simultaneously.
The channels can share video data across video channels to
facilitate edge blending or distortion correction in multi-link projectors.
All correction coefficients are downloaded via USB 2.0 interface.
Correction coefficients map
each outgoing pixel from an area in the source image plane.
For example, assume outgoing pixel (1, 1)
is mapped from pixel location (4.2, 2.7) in the source image plane.
Outgoing pixel (1, 1) is derived from the four nearest neighbors of location (4.2, 2.7)
via bilinear interpolation.
DCP highlights include
6 channels of single link DVI
internal data sharing between channels for geometric correction and edge blending
each outgoing pixel being mapped from the source image plane and
derived via bilinear interpolation
each outgoing pixel having alpha value for uniformity correction and edge blending
and the typical latency through the DCP is 1 - 3 milliseconds.
The DCP is suitable for correcting a 2x2 array of ultra-short throw projectors.
Here we see the 2 upper projectors are mounted upside down
and the 2 lower projectors are mounted right-side up.
With correction factors applied we see a fully blended geometrically correct display.
In this example, the correction factors were calculated by Mersive’s Sol (TM) software
available separately through Mersive.
The DCP is suitable for correcting a 2560x1600 projector on a curved surface for an avionic application.
The 2560x1600 projector is driven via
two 1280x1600 video streams and the projector is mounted sideways.
To perform the desired correction data must be shared between these channels by the DCP.
With user-defined correction factors already downloaded
we click the warp enable button and see a geometrically altered display.
In this example the correction factors were calculated by our customer.
They downloaded a 16x16 mesh that defined the desired warp
across the entire 2560x1600 image.
