Recently multi-media projectors became commercially available for using in 3D reconstruction application. They have a number of features which make them attractive for using in photogrammetric application. The main of these features are high technical characteristics (such as brightness, contrast, signal/noise ratio, resolution) and a reasonable price. And the main advantages of multimedia proj...

A dynamic infrared (IR) scene projector which is based upon diode lasers is now operational at the US Army Missile Command's (MICOM) Research, Development, and Engineering Center (RDEC). The projector is referred to as the Laser Diode Array Projector (LDAP). It utilizes a 64-element linear array of Pb-salt diode lasers coupled with a high-speed optical scanning system, drive electronics and syn...

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...

For acoustic identification of objects in a littoral environment, there are generally three frequency bands of interest; 1 kHz to 10 kHz, 10 kHz to 100 kHz and 100 kHz to 1 MHz, where the selection of these bands is dependent upon the specific Navy mission. This paper will discuss the progress of the Naval Research Laboratory in developing acoustic projector prototypes to address the lower two ...

Multi-projector displays require a variety of image correction techniques. Geometric distortions resulting from projecting onto non-planar display surfaces and non-linear properties of projector lenses must be corrected to produce usable images. Photometric issues such as varying luminance response between projectors and brightness discontinuities in projector overlap regions must also be corre...

Recently, projector camera systems have been used actively for image synthesis and for 3D reconstruction. For using the projector camera systems in these applications, it is very important to compute the geometry between projectors and cameras accurately. Recently, it has been shown that by using the mutual projection of cameras, multiple cameras are calibrated quite accurately. However, this p...

Imagining the future helps anticipate and prepare for what is coming. This has great importance to many, if not all, human endeavors. In this paper, we develop the Planning Projector system prototype, which applies plan-recognition-asplanning technique to both explain the observations derived from analyzing relevant news and social media, and project a range of possible future state trajectorie...

During the last few years, projector phones have been introduced both at a prototype and commercial level. Nevertheless, the functionality with off-the-self projector phones is very much limited to projecting content on a surface next to the user. In this paper, we examine the basic input phenomenon in order to explore the user experience for further interactive concepts with projector phones.

Projection systems have become the ubiquitous infrastructure for presentation technology. However, unless the projector is precisely aligned to the presentation screen, the resulting image suffers from perspective (keystone) distortions requiring manual optical or digital correction. This tedious process must be repeated whenever the projector or screen is moved and is increasingly relevant giv...

Projection systems have become the ubiquitious infrastructure for presentation technology. How-ever, unless the projector is precisely aligned to the presentation screen, the resulting image suffersfrom perspective (keystone) distortions requiring manual optical or digital correction. This tediousprocess must be repeated whenever the projector or screen is moved and is increasingly ...
