360° VIDEO STITCHING FOR DUAL FISHEYE CAMERAS

Back-to-back dual fisheye camera configuration offers a cost-effective 360 degrees video solution. However, the inherent parallax of this camera configuration and the unmatched scene along the seam between the two camera views present a great challenge to video stitching. To address the jittering and fragmented visual appearance issues, we present in this paper a robust method that preserves the geometric structure of the scene and enhances the stableness of the video along the temporal dimension. The proposed video stitching method entails a mesh deforming operation prior for the minimization of the geometric distortion and an adaptive seam carving operation that generates optimal spatial and temporal alignment. Experimental results show that our method can produce 360 degrees videos without jitter and ghost artifact.
