Resolution Improving Method from a Sub-pixel Displaced Omnidirectional Image Sequence

The omnidirectional image sensor, called HyperOmniVision, can observe a 360 degree field of view and can transform an input image to a common camera image or a panoramic image easily. However, it has an intrinsical problem that the angular resolution of HyperOmniVision is lower than that of a conven...

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