ABSTRACT
When probing an object we would like to choose point probes that allow the minimum variation of the ob ject pose. Our point probes inherently contain some known error so it is not enough to take k indepen dent measurements to constrain k degrees of freedom. The placement of the probes effects the worst case ob ject displacement. Therefore, we are interested in the relationship between the object displacements and the corresponding probe displacements. Our goal is to find a set of probe placements that minimizes the potential worst case object displacement.
