X-WARP |
|
X-WARP software is a sophisticated feature included with every MediaZone digital signage system purchase, allowing users to correct geometric distortions introduced when projectors are placed at extreme angles beyond the range of built-in keystone correction, in unusual positions or used to project onto non-flat surfaces. It can also be used to add special effects to any digital signage screen. Please note that X-WARP is bundled only on MediaZone systems that are supplied turnkey (including media player). It is not supplied on MediaZone software-only orders.

With X-WARP, users can map a two-dimensional projected image onto a 3-D surface by adjusting the X-WARP mesh to match the x, y and z coordinates of a three-dimensional surface. Align ProjectorsWhen multiple projectors are used, X-WARP provides an easy, time-saving method to perfectly align the images from each projector.
Above, four projectors for four screens aligned edge to edge in a landscape fashion are used as rear projectors to create one continuous image along a hallway. Unfortunately, each introduces its own geometric distortion based on its position relative to its screen. Aligning the images from each projector is extremely difficult at best and perhaps impossible, so the goal of creating a continuous horizontal image may not be possible.
Above, images from the four projectors are easily and quickly aligned with Keywest Technology's X-WARP. During setup, the projected X-WARP grid pattern from each projector and the application's easy-to-use interface allow the corners of each projected image to be matched while X-WARP's geometric distortion correction algorithms compensate for any distortion, effectively removing it. Curved SurfacesX-WARP can correct geometric distortions caused by projecting a flat image onto a curved surface. In the extreme, that ability would allow them to wrap a projected image around column or pillar.
The complex geometry example illustrates a projector offset creating a horizontal keystone problem. The application is further complicated by the wave-shaped screen.
Using X-WARP, the first step to correct the
distortion is to offset the keystone using X-WARP software by pulling
in the upper and lower left corners. The next step is to use the X-WARP
alignment grid to create a projection warp map. The map is immediately
applied to the output video, effectively cancelling the geometry of the
screen. |
