问题
I've asked a lot of image-stitching-related questions here due to the fact that I'm SOO dumb to understand certain things :(
I'm currently working on a homography-based multicamera image stitching and having some problems that I can't solve by myself. I use Visual Studio 2008/2010 and OpenCV 2.3.1 to work on my project.
I'm gonna describe them below:
First of all, I've put some stuff(code, video...etc) that'll be mentioned later in the following link as I'm limited to post 2 links at most currently...

Plz take a look at the video "Stitching_HomographyBased.avi", which exists in the link mentioned above.
The 12-second video shows how my code is currently working. I use 2 webcams, put them as close as possible and in different orientations with rougly 30%~50% overlapping region. Image 1 and Image 2 show the images taken by the 2 cameras separately. The wider window, of course, shows the aligned(stitched) panorama.
However, the video shows a problem that the warped image is not correctly aligned(see 0:04, where my lab mate stands at the border of the 2 images)
After having some survey on related studies, I guessed that one of the main reasons that lead to this result may be due to the fact that I didn't do camera calibration on both cameras and the radial and tangential distortions cause the error. Is what I guess correct or there may be some other factors that also make this mismatch happen?
I then tried to do camera calibration with an existing code for camera calibration and a chessboard, but I just kept getting weird results. Plz see another video named "BadCalibration.avi" in the link. What's wrong with the way I calibrate the camera?
My code is also uploaded in the link above and it's named Stitching1024.cpp
Thanks for all the helps.
