“…Using a projector augmented by two stereo cameras, Cotting et al [8,9,12] estimate the shape of the display surface and the pose of a single projector continuously over time by embedding imperceptible calibration patterns into projected imagery. Zhou et al [27] achieve the same by tracking displayed image features. Johnson et al [13] show that multiple such units can be used in a distributed framework to achieve continuous geometric calibration in a multiprojector setup.…”

In this paper we present a novel technique to calibrate multiple casually aligned projectors on a fiducial-free cylindrical curved surface using a single camera. We impose two priors to the cylindrical display: (a) cylinder is a vertically extruded surface; and (b) the aspect ratio of the rectangle formed by the four corners of the screen is known. Using these priors, we can estimate the display's 3D surface geometry and camera extrinsic parameters using a single image without any explicit display to camera correspondences. Using the estimated camera and display properties, we design a novel deterministic algorithm to recover the intrinsic and extrinsic parameters of each projector using a single projected pattern seen by the camera which is then used to register the images on the display from any arbitrary viewpoint making it appropriate for virtual reality systems. Finally, our method can be extended easily to handle sharp corners -making it suitable for the common CAVE like VR setup. To the best of our knowledge, this is the first method that can achieve accurate geometric auto-calibration of multiple projectors on a cylindrical display without performing an extensive stereo reconstruction.

“…Though there is a large body of literature that addresses such a reconstruction and registration [19,8,9,12,27,13,11,22], these are complex procedures requiring camera calibration and multiple physical fiducials on the display surface. Hence, many methods try to avoid the complexity of using multiple cameras when using non-planar screens.…”

Abstract-In this paper we present an intuitive interaction technique for everyday objects. We propose a system that allows the user to interact with everyday objects, and use them to make smart scenarios. We enrich the objects with a portable projected interface that is supported by 3D accelerometer in order to build novel user object interaction scenarios. Moreover, we present double crossing as an interaction technique for manipulating finger interface. We conducted experiment to test the applicability of the proposed system with different applications. Our results showed that the proposed system has a lot of potentials to enrich different domains of applications like object data storage, education Montessori cubes and smart shopping goods.Index Terms-Object gestures, handheld projector, ubiquitous environments and portable interface interaction.

“…However, our previous studies mainly focus on calibrating a projected image onto a 2-D plane, for example, making one or more projectors display a stitched and undistorted image on a surface of unknown geometry. [13][14][15] Meanwhile, there are few reports in the literature of flexible and efficient calibration dedicated for multiprojector-type 3-D displays so far. Different from the calibration of a 2-D image, the light rays in a 3-D scene are considered as vectors such that projected images are interpreted as a combination of vectors.…”

Abstract. An automatic geometrical calibration approach has been developed to calibrate a multiprojector-type light field (LF) display automatically and accurately. The calibration framework based on image mapping is detailed, which transfers the calibration of three-dimensional (3-D) scene into the calibration of two-dimensional image in the diffuser interface. A multiprojectors-type LF display prototype is applied to implement the experimental calibration. Comparison results of the reconstructed 3-D scene before and after calibration show that a better overall performance is obtained through the proposed calibration approach. © The Authors.
