Images of Port-au-Prince

This DVD contains three 12-bit gray and quadriband images, each of size around 1GB. We have worked on a crop of size 4096x4096 around the presidential palace.

View from the ground

This is a view from the "fort national" (the elevation at the top-right corner of the images below). The image was copied from an online newspaper.

Reconstructed views

This is a sequence of views of the computed point cloud from three pleiades images. You can download the .ply file [62MB] (with co-ordinates re-mapped to the input image domain, and a 2x vertical exageration).

Zoomed-out input images

These are colorized visualizations of the input images (only the panchromatic versions were used for the stereo reconstruction). The color of the vegetation is enhanced because the infrared channel was combined with the green channel (and the trees are very bright in this band of infra-red).

Full-resolution crops

Notice that the computed heights are essentially correct. There are artifacts due to the following reasons: moving cars, reflections, lack of information on the shaded areas, and thin structures.

Affinely registered images

These registered images help to identify visually the disparities. Notice in particular the destroyed church near the top of the whole image, or the pyramidal tower near the palace (which is visible in the photography below). Notice that fine structures like the walls of the falllen church or the wall of the palace are correctly recovered.
