Embodiments of the present disclosure provide a 360-degree panoramic video playing method, an apparatus, and a system. The method includes: receiving, by a video player, a search instruction, and displaying, according to the search instruction, locating information of a 360-degree panoramic video, where the locating information includes descriptive information of playing content in multiple angle ranges of the 360-degree panoramic video, and the descriptive information is used for determining the playing content in the multiple angle ranges; and receiving a switching instruction, and switching a playing angle range of the 360-degree panoramic video from an angle range of current playing content to a first angle range according to the switching instruction, where the first angle range is an angle range selected by a user from the multiple angle ranges.

360-degree panoramic video playing method, apparatus, and system

An optical flow tracking method includes generating a random structure according to an object to be tracked in an image, where the random structure includes at least two structure blocks with fixed relative positions; tracking all structure blocks in the random structure using an optical flow tracking algorithm to obtain a position offset of the random structure; and estimating a target position of the object according to the position offset of the random structure. According to the optical flow tracking method and apparatus provided in embodiments of the present invention, characteristic points of an object in an image are obtained, and a random structure is generated according to the characteristic points, and each random structure is tracked to obtain a position offset of the random structure, so as to estimate a position of the object, thereby reducing tracking errors and effectively improving tracking precision.
