Methods are described for computer analysis of image-data from a coded
-stripe rangefinder. The main objective is to find vertex coordinates
and connectivity information for a polyhedral object, enabling it to b
e represented by a wire-frame model. For each of several rangefinder v
iewpoints, the data is processed to extract three-dimensional edge and
vertex positions. The emphasis is on estimation techniques that make
good use of fairly sparse data-points. Results from different viewpoin
ts are merged to produce a 3D model of the object.
