Conventional light striping systems capture 3D data by stereo reconstruction and employ encoding systems to solve the correspondence problem. A confounding factor in this overall framework is the interaction of light with surfaces. Light is absorbed by materials and current methods tend to perform poorly for dark objects. We present a new approach to projector-based structured light that uses r...

I investigate a new approach for determining the pre-warp homography required to correct a projector image for perspective when projecting on a single flat surface. By using a depth camera placed at a fixed transform near the projector, the normal of the surface can be predicted in real time. By updating a homography on the image to be projected based on the projector intrinsics and the surface...

This paper describes our design and implementations of projector-based computer augmented environment that allows users to interchange digital information between a computer and physical objects. We propose flexible and practical methods with low-cost projector display system only with a dual monitor personal computer although most previous approaches require high-cost equipments and complex te...

Digital projectors have been steadily becoming smaller and cheaper, and are now used to augment various surfaces with digital information. However, in situations other than the ideal dark room with a perfect white screen we must contend with ambient light and non-uniformity in surface colour, which will reduce the contrast of the output and introduce visible irregularities. Here we present a me...

The primary objective of this article is to explain about touch projector technology concept and how to use it. This paper intention is to look at the present touch projector as a new technology aimed to enable performing tasks as a huge touch screen. This paper briefs on the historical background and provide review of three recent devices which are Touch Pico, Cicret Bracelet and Dell Interact...

This research presents a novel method to calibrate a microscopic structured light system using a camera with a telecentric lens. The pin-hole projector calibration follows the standard pin-hole camera calibration procedures. With the calibrated projector, the 3D coordinates of those feature points used for projector calibration are then estimated through iterative Levenberg-Marquardt optimizati...

This paper provides a classification of calibration methods for cameras and projectors. From basic homography to complex geometric calibration methods, this paper aims at simplifying the choice of the methods to perform a calibration regarding the complexity of the setup. The classical camera calibration methods are presented. A comparison gives the pros and cons for each method. For the projec...

Projector-based embedding has recently emerged as a robust multiscale method for the calculation of various electronic molecular properties. We present the coupling of projector embedding with quantum mechanics/molecular mechanics modeling and apply it for the first time to an enzyme-catalyzed reaction. Using projector-based embedding, we combine coupled-cluster theory, density-functional theor...

In this paper we present a new approach for cooperation between mobile smart objects and projector-camera systems to enable augmentation of the surface of objects with interactive projected displays. We investigate how a smart object’s capability for self description and sensing can be used in cooperation with the vision capability of projector-camera systems to help locate, track and display i...
