This paper presents a self-calibrating camera-assisted presentation interface that enables the user to control presentations using a laser pointer. The setup system consists of a computer connected to an LCD projector and a consumer-level digital camera aimed at the presentation screen. Although the locations, orientations and optical parameters of the camera and projector are unknown, the proj...

The three-dimensional measurement system with a binary defocusing technique is widely applied in diverse fields. The measurement accuracy is mainly determined by out-of-focus projector calibration accuracy. In this paper, a high-precision out-of-focus projector calibration method that is based on distortion correction on the projection plane and nonlinear optimization algorithm is proposed. To ...

In this study, we investigated the use of successive omnidirectional appearance manipulation for the cooperative control of multiple projector camera systems. This type of system comprises several surrounding projector camera units, where each unit projects illumination independently onto a different aspect of a target object based on feedback from the projector cameras. Thus, the system can fa...

We present a robust calibration method for aligning a camera-projector system to multiple planar surfaces. Unlike prior work, we do not recover the 3D scene geometry, nor do we assume knowledge of projector or camera position. We recover the mapping between the projector and each surface in three stages. In the first stage, we recover planar homographies between the projector and the camera thr...

We study embeddings of continuous dynamical systems in larger dimensions via projector operators. call this technique PEDS, projective embedding systems, as the stable fixed point dynamics are recovered projection from higher dimensional space. In paper we provide a general definition and prove that for particular type operator rank-1, uniform mean field projector, equations motion become appro...

Abstract - Screenless display is an emerging new technology, allows users to and transmit data without the use of a screen or projector has become good prospect in near futurefor wide range applications. As name implies it deals with several things screens using projector. It involves following 3 different working principles.The Visual image, Virtual retinal display, Synaptic interface. This ma...

Dense surface acquisition is one of the most challenging tasks for optical 3-D measurement systems in applications such as inspection of industrial parts, reverse engineering, digitization of virtual reality models and robot guidance. In order to achieve high accuracy we need good hardware equipment, as well as sophisticated data processing methods. Since measurements should be feasible under r...

This paper describes the creative process behind an artwork that combines and projects data in sculptural ways. This projection comes in the form of a reimagined magic lantern device called the Magic Lantern Horror Vacui Data Projector. This device is the result of collaborative glass art and electronic art techniques. Central to the projection system are re-envisaged glass magic lantern slides...

This paper presents an approach of using a steerable projector and camera unit in order to augment instrumented environments with projected virtual objects. The environment appears to be covered with a kind of invisible virtual layer on which images, texts, videos, computer desktops and other virtual objects can be placed. By steering the projector beam on particular surfaces the objects placed...

The aim of this thesis to perform geometric self calibration of a projector camera system using only a smartphone and a small projector. The developed system is capable of performing Structured Light Scanning with off-the-shelf devices, namely a Nokia N900 smartphone and an Optoma PK 320 pico projector. We decouple the projector from the smartphone, which is our computational device and our cam...
