TwoViewUnsynch

Tool for synchronizing two image sequences using epipolar geometry or homography Based on the paper: http://openaccess.thecvf.com/content_cvpr_2017/papers/Albl_On_the_Two-View_CVPR_2017_paper.pdf

Function

Synchronizes two image sequences based on tracks provided by the user or computed by OpenMVG (windows only binaries).

Input

  • Image tracks (image points corresponding to the same 3D point in both sequences)
  • Images or video sequences (optional if tracks provided)

Output

  • The time offset between the two sequences.

Track file format

n1 id11 x11 y11 id12 x12 y12 ... n2 id21 x21 y21 id22 x22 y22 ...

Each line is one track

  • n1 - number of image points in sequence 1 for this track
  • id11 - frame in which image point 1 appeared in sequence 1
  • x11, y11 - image coordinates
  • n2 number of image points in sequence 2 for this track
  • etc.

Notes

Images must contain movement. The movement should span more frames than the amount of desychnronization
