Abstract(in English)	In this paper, we report a system to track an object moving parallel and vertical to the lines of sight of observing camera. Dilational and rotational motion in the cartesian image coordinates are mapped to translations in the log-polar coordinates, and thus easily estimated by using a general method. Although, translations in the cartesian coordinates are much complicated ion the log-polar coordinates, they have a remarkable characteristic with periodicity in the mapped domain. Thus the translational motion can be efficiently estimated in the log-polar cooridnates. A tracking system is constructed with a CCD camera of which pan, tilt and zoom are externally controlled. This system can track a moving object with processing speed of 12frames/second without extra hardwares.
