This paper describes a method to estimate the temporalalignment between N unsynchronized video sequences captured by cameras with non-overlapping fields of view. The sequences are recorded by stationary video cameras, with fixed intrinsic and extrinsic parameters. The proposedapproach reduces the problem of synchronizing N non-overlapping sequences to the robust estimation of a single line in R^{N+1}. This line captures all temporal relations between the sequences and a moving sensor in the scene, whose locations in the world coordinate system may beestimated at a constant sampling rate. Experimental results with real-world sequences show that our method can accurately align the videos.
