چکیده انگلیسی


• Multi projector rendering allows immersive projection on large projection surfaces.
• Such multi projector schemes require dedicated GPU based systems to perform rendering.
• Our work proposes an embedded and standalone system for performing multi projector rendering.
• The system applied the geometric correction in real time without using LUTs.

Multi-projector displays allow the realization of large and immersive projection environments by allowing the tiling of projections from multiple projectors. Such tiled displays require real time geometrical warping of the content that is being projected from each projector. This geometrical warping is a computationally intensive operation and is typically applied using high-end graphics processing units (GPUs) that are able to process a defined number of projector channels. Furthermore, this limits the applicability of such multi-projector display systems only to the content that is being generated using desktop based systems. In this paper we propose a platform independent FPGA based scalable hardware architecture for geometric correction of projected content that allows addition of each projector channel at a fractional increase in logic area. The proposed scheme provides real time correction of HD quality video streams and thus enables the use of this technology for embedded and standalone devices.
