APPENDIX B
STAGING AND PRESENTATION
To measure or inspect a part or object, it must be positioned so the camera can see it. Positioning,
sometimes called staging, presentation, or fixturing, puts the part in the camera’s field of view
(FOV), signals the Vision Appliance that a part is available, and helps hold the part steady while
an image is being taken.
The camera is responsible for generating an electronic image of the part for processing by the
Vision Appliance. The camera and lighting help with the part positioning because they are used
to “freeze” or “stop” the motion of a moving part.
An Example
Figure 17 illustrates a bottle inspection line, seen from above. The bottles move along a conveyer
belt, past the camera. The conveyer belt positions the bottle in front of the camera, so that the
camera can capture an image of the threading on top of the bottle’s neck.
