Project 6: Detection of multiple
light sources from a single image of object with known geometry
Description
·
Implement
V2R algorithm on a sphere of known radius (no opposite lights).
·
V2R
algorithm is described in "Multiple
Light Source Detection," Christos-Savvas Bouganis, Mike Brookes.
·
Extend
V2R algorithm to textured spherical objects of known radius.
·
Test
it on real objects with 2 and 3 light
sources.
Results
The recovered
sources should be compared to true sources.
Data sets
Take several images of
textured matte ball under different
configurations of two and three light sources. No opposite lights, no directly
frontal light and no lights behind the object . Construct 3D normals of the
ball and register the model with the images. Albedo of the ball can be acquired
by taking a picture of the ball under bright day light or with flash. Note that
albedo image should be precisely aligned with the test images. This can be
achieved by taking all the images without moving the camera and the object.
