Casting digital-controlled light over real object surfaces, thus creating new textures and special effects, brings to designers and engineers an endless spectrum of possibilities and innovation for their projects. This technology, called Spatial Augmented Reality, can be considered as a kind of "virtual material" that can be manipulated by designers in augmented environments. In order to achiev...

Structured light surface scanners are usually limited to a single projector and cannot provide full profile in scan. Multiple projectors must be employed extend the imaging area over whole of imaged object. Using multiple is challenging problem due inter-projector interference which make pattern decoding hard. We describe practical approach multi-projector structured scanning based on sinusoida...

While an increasing number of operation planning systems enable surgeons to preoperatively define and plan complex surgical interventions, providing these planning data intraoperatively in a reasonable way is still a challenging task. We have developed a new system using projector based augmented reality for the intraoperative visualization of preoperatively defined surgical planning data. Proj...

PURPOSE Digital forward and back projectors play a significant role in iterative image reconstruction. The accuracy of the projector affects the quality of the reconstructed images. Digital breast tomosynthesis (DBT) often uses the ray-tracing (RT) projector that ignores finite detector element size. This paper proposes a modified version of the separable footprint (SF) projector, called the se...

In this paper, we propose a real-time calibration technique for a projector-camera system, which enables the system to locate the projector even while it is moving. Usually fiducial points are stuck on the screen and the camera tracks both the fiducial points and the quadrilateral illuminated by the projector. Then the projector is located by the tracking. Instead of the fiducial points, our re...

This paper describes recent developments and the current status of the Laser Diode Array Projector (LDAP) Technology. The LDAP is a state-of-the-art dynamic infrared scene projector system capable of generating high resolution in-band infrared imagery at high frame rates. Three LDAPs are now operational at the US Army Aviation and Missile Command's (AMCOM) Missile Research, Development, and Eng...
