摘要

本文提出了一种补偿渐晕和光照效应的球坐标全向图像生成算法。该算法将平面图像转换为球面图像，生成全向图像。针对逼真、无缝的全向视频系统，提出了渐晕和照度补偿方法。我们可以在球坐标上合成拼接后的全向图像的任意角度。实验结果表明，该算法能够有效地生成具有真实视频序列的全向图像。此外，所提出的具有渐晕和照明补偿的全向系统比不考虑上述影响的全向系统约好1-4 dB。

Vignetting and Illumination Compensation for Omni-Directional Image Generation on Spherical Coordinate

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 omnidirectional 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.
