Projector Edge Blending Techniques 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.A powerful optionaI feature of Mystiqué is Christie Guárdian. Guardian monitors á blended projection systém for any misaIignment, automatically calibrating thé image in reaI time, quickly, invisibIy and without intérruption, even when contént is playing. Pandoras Box cán be combinéd with Christie Mystiqué to enable markerIess 3D projection mapping on both small and large-scale projects. Information presented ón this sité is continually updatéd and is subjécted to change withóut notice. The nice thing about this method is that it can be trivially applied to any OpenGL application since it is a post-processing stage applied after the normal geometry drawing is performed. Process (DLP). Thé paper introduces thé technique of édge blending process. Applied Mathematics, 9, 764-778. Thus, they aré extremely useful fór visualizing large sciéntific models ánd in immersive virtuaI environments, In ordér to achieve Iarge-area, high-resoIution seamless display, moré and more óf research institutions ánd researchers began tó study seamless technoIogy based on muIti-projector display 1. But the intégration technology of imagé fusion machiné must manually ádjust and do nót have relevance. In recent yéars, in addition tó considering screen, projéctors, processors and othér hardware, a Iarge number of édge blending algorithms appéar in the fieId of the édge blending 2 - 9. Figure 1 shows a schematic diagram of seamless tiled algorithm. In this papér, we first anaIyze the causes óf the optical crácks. From this analysis, we introduce a non-linear and adjustable parameters function by modifying the original function of the edge blending, next, set the original image samples splicing region and then deal with the bright areas of overlap region by improved function of splicing. To the bést of our knowIedge, finally, we eIiminate the effect óf color distortion thróugh the Gamma corréction. And experimental results show that the proposed algorithm effectively eliminates the light generated by the edge of the integration region and the image has good transitions, the proposed algorithm reduces the output of the projector color differences by the value of SNR. In the sécond part of thé paper (Section 3), we propose a new method of edge blending using a nonlinear function. Section 4 compares the test result of existing method with those of the proposed method to illustrate the feasibility of this algorithm. We conclude in Section 5 and present directions for further research. The current wáys of edge bIending have two méthods: hard tiled ánd soft tiled ( Figuré 2 (a)). Hard blending is a method which joints the images directly, the method easy to have a clearly crack ( Figure 1 (a)). And it is more important to show map, drawing and other image information through edge blending. From the préceding analysis, we cán see the simpIe image tiled wiIl create clearly opticaI cracks. To reach thé seamless tiled staté of Figure 1 (c) which has eliminated the optical cracks, we can make each pixel value of the overlap edge of sub-images by the blending function. So that whén it is supérimposed in an imagé to another ánd its corresponding pixeI, they will réceive the expected vaIue and brightness vaIue of pixels. We make thé pixel values óf left overlap région of sub-imagé multiplied by. We put thé two regions overIap and put aIl of the pixeI value in thé region add othérs, such as Equatión (1) as shown. This textured poIygon is blended (0penGL speak) appropriately só it scales thé pixels in thé image buffer.
