This paper presents an omni-directional image generation algorithm on spherical coordinates by compensating vignetting and illumination effects. The algorithm generates an omni-directional image by transforming each planar image to the spherical image. In this paper, vignetting and illumination compensation methods are proposed for realistic and seamless omni-directional video systems. We can synthesize any point of view from the stitched omni-directional image on the spherical coordinates. Experimental results show that the proposed algorithm can effectively generate the omni-directional image and with real video sequences. Furthermore, the proposed omni-directional system with vignetting and illumination compensation is shown to be approximately 1~4 dB better than that which does not consider the said effects.
