Abstract
This paper describes the calibration of a camera-and-plane-of-light ranging system. Equations are derived which relate the image coordinates in the camera to the external coordinate system. These equations contain coefficients which are functions of the geometrical parameters of the camera/light-source system (focal length, pixel spacing, camera-to-plane-of-light distance, etc.) Several pictures are taken of a test block at different distances, and the geometrical parameters in the equations are varied to achieve a best (least squares) fit to the data. The resulting equations have a remaining error of less than one pixel, and have been used successfully on a parts-acquisition robotCitation
