Abstract
Aerial cinematography relying on camera-equipped umanned aerial vehicles (UAVs), or drones, has revolutionized media production during the past years. Autonomous UAV function-alities are already being employed to a degree, in a manner structured mainly around visual target tracking. From a cinematographic point of view, the desired shot type (i.e., Close-Up, Long Shot, etc.) is the most important factor affecting the artistic result. Achieving a specific shot type depends on the target-to-camera distance and the camera focal length. However, the interaction between UAV/camera motion trajectory (e.g., Orbit, Chase, etc.) and the visual tracker requirements constrains the range of feasible shot types at each time instance. In this paper, which extends previous work, these constraints are explored for a number of standard UAV/camera motion types, UAV shot types are classified and rules regarding shot feasibility over time are analytically derived. The proposed rules are evaluated in a realistic UAV simulation environment and achieve high performance, indicating possible benefits from their integration into an intelligent shooting system.
