This paper describes continuing work with both 2-D and 3-D line-scan vision systems using rotation of both the camera and of an object to produce 2-D images. A rotating line-scan camera arrangement has been used to produce images of an area surrounding the camera stage. Due to the nature of the movement parameter these images can be arranged to cover a variable field of view in the movement axis, i.e.: from as small as 5 degree(s) up to 360 degree(s). This same arrangement has been used to produce images of a rotating object allowing a single 2-D image to contain information from the front, back and both sides of the object of interest. This 2-D system is to be extended into a full stereoscopic line-scan vision system. This will enable an investigation into extracting 3-D coordinate information from both the rotating camera and the rotating object.
