Display of Composite Images in a 3-D Virtual Environment - Steve Fleischer
Project Description
I plan to incorporate a video mosaic
(i.e. a composite image made up of individual images properly aligned)
as the texture-mapped ocean floor in the NASA
Ames Virtual Environment Vehicle Interface (VEVI). This requires
the design and implementation of an algorithm which transforms the
mosaic as it is read to coincide with the proper viewpoint as seen by
the VEVI user. Changes in the user viewpoint should result in a
re-transformation of the composite image.
If time permits, I will also design and implement an algorithm to
remove the effects of non-uniform lighting when images are matched
together to form a mosaic, as the images are read into the VEVI.
Deliverables
The final output for this project will be a fully functional virtual
environment, which filters the input mosaic (if time permits) and
transforms it to the virtual ocean floor, based on the current
viewpoint within the virtual world. All coding will be done in C,
using the WorldToolKit (WTK) world modelling library.
