Abstract


Nowadays, more and more multi - projection system . Geometry , color correction , each projector projection content in order to achieve a seamless multi- projection system . In this paper, these technologies , to achieve a multi- projector calibration system . This article from the coordinate transformation this perspective on the basic principles of geometric correction . This paper also introduces the concept of multiple logical screen , The multiple logical screen projection system to reduce the number of the projector and the computer , greatly reducing hardware costs and energy consumption , but also enhance the stability of the system . To achieve good color calibration effect , it must be based on the projector 's projection principle , to accurately measure some of the properties of the projector in projection color . This paper describes the basic principles of color correction , the projection brightness inconsistent , and propose a consistent projection brightness algorithm, GPU accelerated rendering . This article also describes a multi - projection system , a completely new applications that use to multiple projectors collaborative projection display HDR images . The application breakthrough Levels bottleneck in the total number of Levels greater scalability to achieve the purpose of the projection display HDR images more luminance detail , projection display HDR image brightness, saturation was more real and natural . Finally, the two angles from hardware layout and software modules , made ??a brief introduction of our multi- projector calibration system . Our multi- projector calibration system has been applied in many projects , a good response . The system has strong flexibility , scalability , scalability , and low cost , we believe that the application of the system will be better prospects .
