Identifying the left and right camera from 2 images captured at different time intervals

I have been give with 2 camera images which sees the same scene but captured with different time. I will have to find out which image is being captured by which camera (Which camera is left and which camera is right). Image can be given in either order.

I tried 2 approaches

1) Finding the keypoints and match (Used sift) homography and draw the epipolar lines and then find the intersection of the lines to find the epipoles.

2) Create a mosaic and find out which is left and which is right.

Both these methods are not working in all the cases.

Case 1: when the fixation point is at infinity Case 2: when the fixation point is closer (in foreground)

I looked in to other options like Bundle Adjustment but I am not clear how to do it and where to start.

Any help would be appreciated.

Thank you.
