Planar mapped trajectories (curves composed of time-stamped points) matching differs to other planar curves correspondence in stereo vision. Most methods proposed for general planar curves matching are not much suitable for it. In this paper, a new coarse-to-fine method for planar trajectories is proposed; some physical constraints such as time, height, speed limitation and continuousness of aerocraft trajectories are used to make matching process more reasonable. Similarity Measures between left and right images planar trajectories are calculated for matching, flight trajectories are reconstructed at last, and reconstruction error is also discussed at last.
