HDRchitecture: Real-Time 3D HDR Imaging for Extreme Dynamic Range

Los Angeles Convention Center, Concourse Foyer

HDRchitecture applies high-dynamic-range imaging to electric arc welding, a technique that also shows promise as a general-purpose seeing aid. The system can be used by welding schools and professionals to inspect welding in real time. A fixed camera system (on a tripod) or a stereo EyeTap cybernetic welding helmet with heads-up display records and streams live video from a welding booth to students or observers in nearby or remote locations. It captures a dynamic range more than a million to one, to reveal details that cannot be seen by the human eye or any currently existing commercially available camera. In comparison to most other work in HDR, the system's custom algorithm can run in real time at an interactive frame rate. It can also produce high-quality images in real time, and it embodies other features that have been designed specifically for the extremes of arc welding. The system also enables stereoscopic vision on the heads-up display as well as through external 3D TV displays using NVIDIA 3D vision-shutter eyeglasses.
