Following figure is the image of the 3D object of interest.
Here we assume a metrically calibrated sequence of image. The camera is
calibrated by haveing the same planar calibration checkerboard pattern
in each image used.
In this experiment, seven images were taken (as shown in following
Fig). Among them, three were used for estimating the bottom of the object
and four were used for estimating the lower boundery of the hole in the
object.
In the figure above, the green polygon is the convex hull of the projected
cube boundary. The red courve is the apparent contour of the reconstructed
strface. (a) - (c) are used for reconstructing the surface patch in the
bottom cube. (d) - (g) are used for reconstructing the surface patch in
the cube near the hole.
The following figure (a) shows a 4th degree algebraic surface fit to
data point sampled from the two quardric surface patches.
In the following figure, the white pooint are samples from the
two estimated quadric patches and were used in estimateing the 4th degree
algebraic surface are seen.
Here are some new results - reconstructed model from 14 images.
