    Abstract: The present disclosure provides an optical flow tracking device. The device includes an image pyramid establishing circuit configured to establish a first image pyramid of a first image and a second image pyramid of a second image. The first image pyramid includes one or more image layers, and the second image pyramid includes one or more image layers. The device further includes an optical flow tracking circuit configured to perform an optical flow tracking processing on a kth image layer in the first image pyramid and a kth image layer in the second image pyramid to acquire an optical flow estimator of the second image in the kth image layer. K is an integer. The optical flow tracking circuit is configured to calculate an optical flow of the second image by using the optical flow estimator of the second image in the kth image layer.

    Abstract: A system of virtual sightseeing using unmanned aerial vehicles (UAV) and methods of making and using same. The virtual sightseeing system can include a plurality of UAVs arranged over a geographical area of interest in one or more ground configurations. In response to a sightseeing request, one or more UAVs are activated and deployed to a sightseeing region of interest. The UAVs travel to the region of interest and, upon arriving, acquire data for presentation in real-time. The data can include both visual and non-visual data from the region of interest and can be presented in integrated fashion in a virtual reality terminal. The virtual sightseeing is supervised by an operational subsystem that is responsible for efficient allocation of UAVs in response to multiple sightseeing requests. Even if physically separate, the subsystems of the virtual sightseeing system can communicate via a data communication subsystem, such as a wireless network.
