Seamless system for a wide range of multimedia, high-resolution display of an effective implementation. It brings the large screen, more vivid screen display and clear display makes monitoring, security, conference, simulation and other fields have greatly improved work efficiency, while promoting the rapid progress of industry technical standards. Seamless products abroad have been available, but in order to ensure the confidentiality of technology for the integration of functions used by developers and the related reports of minimal processing.Simple linear function for the current time is not easy to adjust the parameters, this paper amend existing simple linear function, the integration of the introduction of non-linear function, namely, by additional parameters, to amend the existing edge of fusion algorithm with Gamma Operators further correction of the pixel brightness. Against the edge of the light generated by fusion band effect, the edge during this integration process, the pairs of overlapping pixels do fade processing at the edge of the graph in the overlapping area of each pixel is multiplied by the integration of functions, allowing as It is also a word superimposed image, superimposed with the corresponding pixel when the pixel value can be expected.View of the pixel brightness signal and the relationship between the Gamma should meet, it was in the process design of Gamma Correction. Taking into account the different projectors in the projection process will cause the color distortion problem, the effect of color / brightness output matching to do some processing. At the same time, taking into account the special projectors to the projection screen projection arising from the geometric distortion, the paper also introduces the geometric correction techniques for solving geometric distortion.Finally, this paper developed by the digital light projection system on various types of mosaic image simulation test, the image quality and the traditional method for some of the comparison, Cai Yong multiple evaluation indexes, such as pixel Niuqu degree index, spatial index continuous degree Yi Ji signal to noise ratio as an objective evaluation function, based on various perspectives on the edge of fusion effect of different parameters to evaluate and to verify the validity of the digital lighting projection splicing system is effective and practical. This article based on the concept of edge integration and geometric correction technology designed to achieve a seamless soft-edge digital light projection system.
