Real-time video(image) stitching

2012-05-02T15:41:39

I'm thinking of stitching images from 2 or more(currently maybe 3 or 4) cameras in real-time using OpenCV 2.3.1 on Visual Studio 2008.

However, I'm curious about how it is done.

Recently I've studied some techniques of feature-based image stitching method.

Most of them requires at least the following step:

1.Feature detection 2.Feature matching 3.Finding Homography 4.Transformation of target images to reference images ...etc

Now most of the techniques I've read only deal with images "ONCE", while I would like it to deal with a series of images captured from a few cameras and I want it to be "REAL-TIME".

So far it may still sound confusing. I'm describing the detail:

Put 3 cameras at different angles and positions, while each of them must have overlapping areas with its adjacent one so as to build a REAL-TIME video stitching.

What I would like to do is similiar to the content in the following link, where ASIFT is used.

I tried to consult the owner of that video but I got no reply from him:(.

Can I use image-stitching methods to deal with video stitching? Video itself is composed of a series of images so I wonder if this is possible. However, detecting feature points seems to be very time-consuming whatever feature detector(SURF, SIFT, ASIFT...etc) you use. This makes me doubt the possibility of doing Real-time video stitching.
