Paper Abstract

A tracking measurement method is introduced using pan-tilt-zoom cameras based on machine vision theory. The modeling of a pan-tilt-zoom camera system is described. The model formula given represents the relationship between the coordinates of a spatial point and its corresponding image coordinates when the system focus, zoom, aperture and illumination are adjusted to track the measured object. The modeling technique has excellent applicability and facilitates the assembly and alignment of the camera. The only requirement for alignment is to align the image sensor plane parallel to the tilt rotation axis.
