ABSTRACT

Monocular pan–tilt–zoom (PTZ) cameras are widely used in intelligent surveillance, long-range observation, facility inspection, and target detail acquisition because they can actively adjust both viewing direction and imaging scale. Compared with fixed cameras, PTZ cameras provide greater flexibility for capturing useful target images in large-scale scenes. However, static target snapshot with PTZ cameras is not a simple target-centering problem. A useful snapshot should keep the target complete, provide sufficient image scale, and remain robust to real-device errors. This paper provides a brief review of static target snapshot tasks with monocular PTZ cameras. First, the main hardware and system challenges are summarized, including limited field of view, pan–tilt motion errors, zoom-related optical changes, control delay, video stream synchronization, and perception uncertainty. Then, static target snapshot tasks are discussed from single-target and multi-target perspectives. Static single-target snapshot focuses on acquiring a clear and complete view of one target, while static multi-target snapshot further involves target selection, view switching, capture order, zoom planning, and motion-cost reduction. Finally, several future directions are discussed, including full PTZ snapshot planning, real-device-aware modeling, snapshot-oriented evaluation, and open-source experimental platforms.
