Abstract

This paper presents a mathematical basis for judging the quality of camera and projector placement in 3D for structured light systems. Two important quality metrics are considered: visibility, which measures how much of the target object is visible; and scale, which measures the error in detecting the visible portions. A novel method for computing each of these metrics is presented. An example is discussed which demonstrates use of these two metrics. The proposed techniques have direct applicability to the task of monitoring patient safety for radiation therapy applications
