Projector Defocus for Realtime Video
In recent years, projector technology has become ubiquitous in the consumer market. Because of this, we see widespread use of projectors in academic as well as home applications. However, projector technology does have a few limitations. Firstly, projectors have a very narrow depth of field, thus focusing a projector can become a laborious procedure. Furthermore, because a projector essentially...
متن کاملCamera and projector arrays for immersive 3D video
Applying recent advances in multi-imager capture and multi-projector display, we combine capabilities through the Nizza multimedia dataflow architecture to deliver low-cost wide-VGA-quality low-latency autostereoscopic 3D display of live video on a single PC. Supporting multiple users as they observe and interact against a life-sized display surface responsive to their positions, this facility ...
متن کامل3D Shape Recovery with no Explicit Video Projector Calibration
3D shape reconstruction is a common task in many areas of interests. Yet, very often it involves sophisticated hardware and software. This paper represents cheap and simple system, both in hardware and software sense, for 3D subjects shape reconstruction. It consists of video camera(s) and video projector and is based on well known principle of structured light. A major contribution of the pape...
متن کاملUniversal Usage of a Video Projector on a Mobile Guide Robot
In this paper, we present a holistic approach to enable mobile robots using video projection in a situation aware and dynamic way. Therefore, we show how to autonomously detect wall segments that are suitable to be used as projection target in a dynamic environment. We derive several quality measures to score the wall segments found in the local environment and show how these scores can be used...
متن کاملGeneric nonsinusoidal phase error correction for three-dimensional shape measurement using a digital video projector.
A structured light system using a digital video projector is widely used for 3D shape measurement. However, the nonlinear gamma of the projector causes the projected fringe patterns to be nonsinusoidal, which results in phase error and therefore measurement error. It has been shown that, by using a small look-up table (LUT), this type of phase error can be reduced significantly for a three-step...
