Week 6

From my initial idea of using photogrammetry to recreate a scene, like Oxford street over a series of years. I have discovered that i need many more photos than what is available. This led to investigating film, tv and other media as a source for images. This idea could be used to inform design decisions in architecture, recreate scenes from an earlier point in time to be used and manipulated for film, or to document historical changes over time for council records or educational purposes.

At this point i am in the process of reconstructing high definition models a scene from a movie. This process raises a few issues like if you are extracting still images from film, how much of that content is actually real? Are you reconstructing a scene that is already a 3d model? I have reconstructed some test scenes to point clouds, ready to be taken to the next stage as 3d models. From here, these models could be used in applications such as google maps or a series of animations that could show changes over time, possibly combining real video footage and the recreated scene, this way it would be possible to blend past and the future elements.

Church Reconstruction (Point cloud)

Finally a breakthrough! Here we have a model in MeshLab.

When it came to the dense reconstruction, with HD images, it stayed at the above point for 24 hours and didnt move. Im assuming it ran out of memory.
