Auto-construction Of Multi-Projector Large-Scale Displays

Multi-projector, large-scale displays are a system using multiple projectors to achieve large-scale screen, high resolution seamless displays. Construction of multi-projection system technologies is the method solving the image distortion between projector and displays, which is caused by projector posture and screen forms; involving correcting for geometric misalignment; eliminating the projector the color difference of the projector screen. Color differences will destroy large-screen images to a number of parts of the overall consistency of color correction to solve the problem.Multi-projector displays construction methods is an important indicator of the level of automation and methods of application. This research focused on the development of a wide range of application, a high degree of automation of Construction. Large-screen projection system construction methods start with constructing more access to the projector and the camera calibration data, then calibration data analysis to be constructed, the final use of data structures constructed over large projection screen display device.This paper introduces a novel calibration data acquisition methods, in the acquisition process can be constructed more projection system of multi-projector alignment data. The method has the flexibility and more fast than bypass. In addition calibration data acquisition process, Adaptive brightness in the shooting methods and irradiation regional projector automatic extraction methods and other areas of research, new methods greatly reduce the participation of the people, to a large extent, improve the degree of automation.Currently, this multi-large screen projection system is the use of the heritage of digital display areas, for the big scene immersion display.
