Correspondence in road image sequence
Correspondence problem in road image sequence is discussed and a method to establish road correspondence from its perspective image sequence is suggested. The proposed method is mainly based on the features of turn angles of road edge points, while the turn angle for each edge point at one time can be computed from the Frame based on the determination of matching points whin that frame. The turn angles will change from frame to frame according to the Fanning rotation of the camera and, for each stationary edge point, the difference of turn angles between two frames equals the Fanning angle of the camera. Thus we develop an algorithm to estimate the value of Fanning angle of the camera by which correspondence in road image sequence can be established.
