ATCS (Automatic Tracking and Close-up System) is an automatic video camera control technology that can replace a human camera operator in many video-based applications, such as surveillance and remote learning systems. Units based on this technology have a relatively low cost and will therefore make it possible to have controllable cameras in many new areas, where human operators are too expensive. The ATCS technology is superior to other products for use in applications such as video conferencing due to the following features: ATCS can keep track of the true 3D position and motion parameters of multiple objects, all of which may be moving simultaneously. ATCS can detect and track almost any type of dynamic objects without using tags or transmitters. ATCS does not require on-site calibration. ATCS is based on two main components: a detector system and a pan-tilt camera unit. This combination makes it possible for a videocamera using this technology to detect moving objects in a large area, to measure the physical properties of the objects for classification and to select interesting objects on which to focus and track. Object selection strategies can be easily changed for various applications, and thus the same system can be used for many different applications. Until ATCS, systems using only one detector camera were unable to measure the physical properties of moving objects without complicated on-site calibration.
