Abstract
This thesis investigates the technical design of a semi-automated system that repositions a 360° camera to capture images for stereoscopic (3D) 360° panoramas in virtual reality (VR). The system partially automates moving the camera to precise locations and is an improvement over an earlier model. For image synthesis, the thesis proposes using a larger off-center distance—the separation between the left and right viewpoints that creates the 3D effect—and compares this approach with three other display methods. In a study with 24 participants that collected ordinal ratings of comfort, perceived depth, and realism, the larger off-center method was rated significantly better than nearly all alternatives.
Dette speciale undersøger den tekniske udformning af et delvist automatiseret system, der flytter et 360°-kamera for at optage billeder til stereoskopiske (3D) 360°-panoramaer i virtuel virkelighed (VR). Systemet automatiserer delvist at flytte kameraet til præcise positioner og er en forbedring i forhold til en tidligere model. Specialet foreslår at bruge en større off-center-afstand—altså en større adskillelse mellem venstre og højre synspunkt, som skaber 3D-effekten—til billedsyntese og sammenligner denne tilgang med tre andre visningsmetoder. I en test med 24 personer, der indsamlede ordinale vurderinger af komfort, oplevet dybde og realisme, blev metoden med større off-center-afstand vurderet signifikant bedre end næsten alle alternativer.
