Camera arrays are used to acquire the 360° surround video data presented on 3D immersive displays. The design of these arrays involves a large number of decisions ranging from the placement and orientation of the cameras to the choice of lenses and sensors. We implemented an open-source
software environment (iset360) to support engineers designing and evaluating camera arrays for virtual and augmented reality applications. The software uses physically based ray tracing to simulate a 3D virtual spectral scene and traces these rays through multi-element spherical lenses to
calculate the irradiance at the imaging sensor. The software then simulates imaging sensors to predict the captured images. The sensor data can be processed to produce the stereo and monoscopic 360° panoramas commonly used in virtual reality applications. By simulating the entire capture
pipeline, we can visualize how changes in the system components influence the system performance. We demonstrate the use of the software by simulating a variety of different camera rigs, including the Facebook Surround360, the GoPro Odyssey, the GoPro Omni, and the Samsung Gear 360.

More about this publication?
For more than 30 years, the Electronic Imaging Symposium has been serving those in the broad community - from academia and industry - who work on imaging science and digital technologies. The breadth of the Symposium covers the entire imaging science ecosystem, from capture (sensors, camera) through image processing (image quality, color and appearance) to how we and our surrogate machines see and interpret images. Applications covered include augmented reality, autonomous vehicles, machine vision, data analysis, digital and mobile photography, security, virtual reality, and human vision. IS&T began sole sponsorship of the meeting in 2016. All papers presented at EIs 20+ conferences are open access.
Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
