Abstract :
The authors describe an omnidirectional image sensor, called HyperOmniVision, that can observe a 360 degree field of view and can transformed an input image to a common camera image or a panoramic image easily. However, it has an intrinsic problem where the angular resolution of HyperOmniVision is lower than that of a conventional video camera. The authors propose a super-resolution method for HyperOmniVision, which fuses consecutive images obtained the by turning motion of HyperOmniVision. They discuss the optimization of both optics and processing by simulation results
