Abstract

The National Bureau of Standards is developing a vision system for use in an automated factory environment. The emphasis of the project is on the real-time acquisition of three-dimensional parts using visual feedback. The system employs multiple light sources in con-junction with object models to establish the position and orientation of an object in the camera's field of view. A flood flash enables shape information to be obtained from an image, while a plane of light can be used to find the three-dimensional positions of points on the object. Because there are only a small number of object types and the objects all have pre-defined nominal locations, a model can be used to predict how the scene should look from a given viewpoint using a particular light source. This prediction can be compared with the actual image, and the differences used to establish position information. Models are expected to be particularly useful in reducing the number of views of an object necessary to calculate its three-dimensional position.
