Hello, I've been trying to use Hugin to stitch together image mosaics of a planar object (a painting) for some months now. My images are heavily overlapped, but because each image is taken from a different location, I am dealing both with the problem of a shift in the camera viewpoint and using Hugin's current projection model which isn't designed for mosaics. Over the past two months, I have been looking into Hugin's source code and finding my way around. I have made some minor tweaks for my own use such as allowing the use of optimized values of shear_x and shear_y, (a.k.a. g and t.) I have compiled and built Hugin both on Windows and on Linux under Ubuntu.
I'd like to solve the problems I'm encountering as part of Summer of Code. Specifically, I'd like to introduce a mosaic mode to Hugin. This will require the development of the geometric framework to project from the mosaic image viewpoints to that of an orthographic view of the entire painting. I propose calculating the warp using a homography, applying the calculated mapping, and projecting the result to the orthographic viewpoint. A homography estimation algorithm developed in C by Lourakis will provide the required homography matrix calculations. I'm a PhD candidate in Electrical Engineering and Computer Science at Northwestern University, Evanston, Illinois working to develop software that can be used by art historians to study paintings photographed under a wide range of lighting conditions. I hope Hugin will become a vital tool for pre-processing, warping, and stitching images for my project. I plan to upload my full proposal to the wiki soon and look forward to your feedback. I would especially be interested in hearing from potential mentors. From the earlier messages, it's clear that there is great demand for such a feature and I would enjoy working with the Hugin community to make it better for all of us.
