โฆ Synopsis
A problem that arises is getting computers to perceive 3-D scenes is relating informa;tionfrom โข everal different viewpoints. In particular, if the computer moves its sensor~ it has to be able to predict changes in images of objects it has seen without having to completely re-recognize them. A solution to this problem has been implemented at Stanford using a calibrated camera model which expresses the relation between object space and image space as a function of the computer's control variables. The modelling problem is relatively well understood. Calibration techniques, however, are not. This article d~.ais with these.
