eResearch SA has stereoscopic imaging facilities available for researchers who want access to improved depth information and structural representation in their area of study.

We can help you produce stereoscopic images or view 3D images stereoscopically whether you are:

• adding depth information to artwork
• creating archival recordings of architecture or items of historical interest
• examining plant growth via time-lapse stereo photography
• improving realism in online museum displays
• enhancing motion study via stereoscopic acquisition of images.
  

Stereoscopic images are produced using two cameras placed slightly apart but focussed on the same scene. When the resulting images are viewed using stereoscopic hardware, differences between the two are perceived as depth information.

Services

Still images

• Normal and hyperstereo imaging
• Ambient lighting or with camera flash
• Alignment and conversion to appropriate output format.

Video

• normal and hyperstereo imaging
• ambient lighting only
• synchronising, alignment and conversion to appropriate output format.

Limited audio editing (eg over-dubbing) can be arranged.

Editing

• cropping, cleaning, alignment and ouput conversion of digital-format stereo pairs, eg scanned archival stereographic images
• synchronisation, alignment and output conversion of stereo video files (from a suitable digital video format)

Facilities

Cameras

• Still: two Sony DSC-V3 cameras
• Video: two Sony HC-21 mini-DV cameras (PAL, interlaced)
• Video: two Canon XH-G1 HD cameras on a mirror rig which allows arbitrary axial separation up to 110mm

Synchronising unit

Ledametrix LANC Shepherd Pro

Mounting  

Various in-house mounting bars, with Manfrotto tripod and 128RC video head.

Editing

Adobe Premiere Pro for editing video.

Viewing

There are two facilities dedicated to stereoscopic viewing: the VisLab and the South Australian Virtual Reality Centre (SAVRC). Viewing in the VisLab is via the Infitec colour-separation system, and by shutter-glasses in the SAVRC. For video files, we use Stereoscopic Player.

Delivery

Stereo stills and video files can be provided in a variety of formats (side-by-side, above-and-below, as separate files or anaglyphs). For use outside eResearch SA's facilities, the end-user must provide viewing hardware. We will endeavour to provide an output format suited to the user's hardware and software.
