Image Systems Simulation for 360° Camera Rigs
  DOI :  10.2352/ISSN.2470-1173.2018.05.PMII-353  Published OnlineJanuary 2018

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.
