Abstract
This invention proposes a new method and software to generate a path with good quality for aerial video shooting in large scale scenes. Using a coarse 2.5D model of a scene, this path generation method consists of several steps: first the user is expected to specify a set of landmarks and designate a superset of key-views for each landmark; our system then automatically generates and evaluates a variety of local camera moves for observing each landmark, which are smooth and collision-free; then automatically determines the optimal order in which the landmarks should be visited, chaining the local camera moves into a single continuous trajectory. Thus, users are able to focus on specifying the visual content that should be captured by the aerial video, rather than on the difficult lower level aspects of designing and specifying the precise drone and camera motions.
