Leave it to us (LTU) initiative

Univisual Technologies is proud to announce our new initiative; LEAVE IT TO US or LTU for short.

The background for this initiative is the simple fact that a multi-projector projection is not at all easy to set to work. On the contrary, it is very complicated to set up a perfect visual system and it takes years for an engineer to become a master of that trade.  Most warp and blend products are hard to figure out and the user interfaces they offer are more suited for "professors" than "normal" people.

Univisual Technologies have therefore developed an Alignment Toolbox that will ensure an acceptable result just by following a simple procedure, without any need for any prior knowledge about projection systems.  

The first generation Alignment Toolbox included a Quick Setup function that supported swift and easy alignment of 2D content onto any type of screen shapes. A perfect seamless result could be achieved in matter of minutes just by clicking the LUREMUS icon on a few predefined spots on the screen.  For reference, a video film represents a typical 2D content. 

In the second generation Alignment Toolbox we have upgraded the Quick Setup with a unique UTM function. Just by adding the field of view data into the GUI and click the UTM icon, Warpalizer automatically prepares the screen for 3D content.  For reference, most simulators that include a terrain database need 3D warping to be correctly projected.

Possible inaccuracies in the physical construction of the projection system are likely to cause smaller mismatch in the alignment. The second generation Alignment Toolbox therefore also includes provisions for fine adjustment. The fine adjustment is done by clicking, dragging and dropping control points into the correct positions using the LUREMUS icon. 

In most cases sufficient accuracy is achieve by relying on the naked eye only. However, if a higher degree of accuracy is needed, the second generation Tool Box has an option called WarpaLAZER.  The WarpaLAZER is a hardware based reference generator that projects a vertical line every 10 degrees, and a horizontal line in the vertical position the WarpaLAZER is located.  The resulting grid lines can be used to calibrate the control points very accurately. A picture of the WarpaLAZER is added at the end of this article.

The second generation Tool Box has also been augmented with new function, called Auto Line Up.  This function will ensure that the projected image will be perfect at all times, even if a projector has been accidental moved out of position.  Off course there is a limit to how much the projector can be moved, but for all practical purposes the function dynamically remedies normal day to day problems.  

Finally, the second generation Tool Box includes a new function, called Deep Black Overlap. This function removes the light in the overlap zone between two or more projectors, thus making Warpalizer a perfect for night simulation. The function is based on a sophisticated software algorithm in combination with simple antennas located  in front of the projector lenses.

The bottom line is; LTU. You do not have to understand what we do, or how we do it. Just enjoy the result.
