OpenCV non-rotational image stitching

Question

I am doing image stitching in OpenCV, where I am taking pictures of a planar scene from different locations and try to compose a panorama. I have modified the stitching example

Answer 1

The opencv stitching code works by assuming translation to be zero. So if the translation is within a range, it will work fine. Else it will reject faraway images. If you want to use translated image set, you need to use decomposehomgraphymat which will give nonzero translation adn rotation. But for warping and blending opencv uses rotation of camera parameter only. So you need to devise a complete new method for non-rotational stitching, maybe you look into microsoft photosynth work. I am not sure, but it does work for only translated images.
