The goal of this assignment is to build a 3D scanner using one or more digital cameras and a single projector. While the “desktop scanner” [2] implemented in the previous assignment is inexpensive, it has limited practical utility. The scanning process requires manual manipulation of the stick, and the time required to sweep the shadow plane across the scene limits the system to reconstructing ...

It is well known that the properties of micro LED display have higher contrast ratio, brightness, high reliability, and much faster response time than conventional LCD OLED displays. We demonstrate a prove concept (POC) pico-projector prototype with F/0.9 camera lens, green panel, digital driving board. The lumen output from POC only about 1 Lumen. calculate if larger size plus lens array, thre...

It is well known that the homogeneous differentiator strategies reduce chattering in implementation of sliding-mode algorithms and recent implicit framework based projector provides very interesting properties when associated with design. In this article, it proposed to evaluate different differentiators on Euler explicit promising semi-implicit strategies, for which discrete implementations ha...

Emerging phone handsets include embedded projectors that will provide a widespread new form of display for mobile users. However, it is not clear how the handheld projector will be used alongside the existing phone screen. The current approach of many manufacturers is to place the projector in the top of the phone. This typically prevents users from simultaneously interacting with the phone and...

Projection-based stereoscopic wall displays allow users to immerse themselves into virtual scenes, such as architecture simulations or games. However, the usually low resolution (dpi) of such displays and slight alignment offsets between the two projectors result in a loss of detail and bad readability of textual information. We propose addressing the problem by overlaying a third projector, so...

The tachyon vacuum solution of Schnabl is based on the wedge states, which close under the star product and interpolate between the identity state and the sliver projector. We use reparameterizations to solve the long-standing problem of finding an analogous family of states for arbitrary projectors and to construct analytic solutions based on them. The solutions simplify for special projectors...

To use a projector anytime anywhere, a lot of projectorcamera based approaches have been proposed. In this paper, we focus on a focal correction technique, one of projector-camera based approaches, reduces an effect of defocus blur which occurs when a screen is located out of projector’s depth-of-field. We propose a novel method for estimating projector defocus blur on a planar screen without a...

The concept of tiled displays can be successful only if such displays are made to look like a single display perceptually. The two issues that need to be solved to achieve this goal are geometric correction and color seamlessness of images spanning across tiles. Geometric correction algorithms borrow pin-hole camera models to model projector display geometry. In this paper, we introduce an abst...

We present some ideas and demonstrations for a hybrid projectorbased rendering and display technique we call Computer Graphics Optique. Instead of partially overlapping projected images to achieve a wide-area display, we completely overlap projected images on top of each other to achieve the addition of light and color in an “optical composition buffer.” The idea is to use the optical compositi...
