Abstract
An important aspect of inspection planning involves determining
camera poses based on some criterion. We seek to find camera
poses where the effects of displacement and quantization errors are
minimal. The mean squared error is formulated, including all
dependencies, and minimized to determine an optimal camera pose that
satisfies the sensor constraints of resolution, focus, field-of-view,
and visibility. Dimensional tolerances for line entities are also
formulated and exploited to determine the acceptability of a given
camera pose for all entities observed.
