Edge Blending Processor Software Automatically AlignsAt the click of a mouse, the camera-based software automatically aligns, stacks and blends multi-projector systems in minutes, with unsurpassed accuracy. Get started with our Mystique Lite software for simple setups. Guardian monitors a blended projection system for any misalignment, automatically calibrating the image in real time, quickly, invisibly and without interruption, even when content is playing. Pandoras Box can be combined with Christie Mystique to enable markerless 3D projection mapping on both small and large-scale projects. Information presented on this site is continually updated and is subjected to change without notice. Other commonly encountered regular-shaped surfaces are subway walls and pillars. You can help. The talk page may contain suggestions. May 2013 ). The term Image Geometry Correction, implying a static image, is slightly misleading. Image geometry correction applies to static or dynamic images (i.e. The spatial transformation must be pre-defined for a particular desired geometric, and may be calculated by several different methods (more to follow). The transformation is executed by texture mapping from the rectilinear mesh of the input image to the transformed shape of the destination image. Each polygon on the input image is thus applied to an equivalent (but transformed in shape and location) polygon in the output image. The sophisticated software that uses the texture mapping hardware of a graphics controller is not standard, and is available only through vendors of specialty software (i.e. Mersive Technologies and Scalable Display Technologies). Its major drawback is that it is tied to the graphics controller platform, and cannot process signals that originate outside the graphics controller. The scaling operation is performed with different scaling ratios in different parts of the image, according to the defined transformation. Special care must be taken in the design of the scaling filter to ensure that spatial frequencies remain balanced in all areas of the image, and that the Nyquist criterion is met in all areas of the image. The drawback of Signal Processing based Image Geometry Correction is the extra expense of the hardware that is used to perform it. The image geometry correction transformation can be calculated by predictive geometry (i.e. In all methods, the transformation is generally described as a 2-dimensional array. The number of points in the 2-dimensional array that are required to do an accurate Image Geometry Correction depends on the surface involved. In the case of Keystone Correction, 4 points are all that are required to completely describe any projection situation. Keystone distortion gets its name from the symmetric trapezoidal distortion resulting from misaligned projector placement in the vertical dimension (although the term is generally applied to the non-symmetric quadrilateral shape that occurs from an off-axis projection in both dimensions). Keystone correction capabilities are now included in most projectors currently available on the market, allowing users to move the image both vertically and horizontally. Even with this feature, the degree of adjustment available is limited, and image quality may suffer. Keystone correction is ideal for simple business (i.e. For more complex distortion correction, an external processor is required. In this application, two or more projectors are projected onto exactly the same surface. Since the two projectors cannot occupy exactly the same space, the output of each must be at least slightly corrected for Keystone Distortion.
