Title:


    HDRchitecture: Real-time Stereoscopic HDR Imaging for Extreme Dynamic Range

Presenter(s):


Entry Number: 11


Description:


    In this demonstration, we present extreme HDR adapted for use in GlassEyesTM (EyeTap) electric arc welding helmets, as well as for a general-purpose seeing aid.

    Our “WeldCam HDRchitecture” (abbreviated “HDRchitecture”) system uses one or more cameras, and optional active illumination systems, that can be used by welding schools and professionals to inspect welding in real-time. We present HDRchitecture as either a fixed camera system (e.g. for use on a tripod), or as a stereo EyeTap cybernetic welding helmet (see Figure 1) that records and streams live video to observers, nearby or remote. By capturing a dynamic range of more than a million to one, we can see details that cannot be seen by the human eye or any currently existing commercially available cameras.
