Abstract
A topological panorama camera has a track or other system upon which a linescan camera can move in one, two or three dimensions while recording the image of an object. The path, speed, acceleration, scan rate and direction of the linescan camera can be controlled, as can the path, speed, acceleration and direction of the object. A pattern is projected onto an object of arbitrary shape and is imaged by the topological panorama camera in one or more passes. The image of the pattern received by the camera is analyzed to determine the exterior shape of the object.

A method of determining the shape of an object, comprising the steps of:
- scanning the object through an optical slit moving using relative motion between the slit and the object while projecting light on said object in a predetermined sequence to form a pattern on the object and recording an image of a reflection of said pattern received through said optical slit as the object is scanned;
- and
- analyzing the geometric properties of the reflection of said pattern to determine the shape of said object.
Apparatus for determining the shape of an object, comprising:
- an image receiver for scanning the object through an optical slit moving using relative motion between the slit and the object;
