Abstract

The invention discloses a shot type determining method and device. The method comprises the following steps: two adjacent frames of pictures in a shot are respectively subjected to characteristic point detection operation, characteristic points are extracted, the characteristics are purified according to effective dense zones in the two adjacent frames of pictures, region density of the effective dense zones and a matching degree of the characteristic points in the zones meet preset conditions, the purified characteristic points are used to determine a transformation relation between the two adjacent frames of pictures, a latter one of the two frames of pictures is subjected to picture transformation operation according to the transformation relation, and the type of the shot is determined according to a former frame of picture and the transformed latter frame of picture. According to the shot type determining method and device, the two adjacent pictures in the same shot are subjected to matching operation so as to determine the type of the shot, and therefore automatic shot type identification can be realized; the effective dense zones are subjected to matching operation, and characteristic point matching accuracy can be improved while picture matching speed can be ensured.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a method and device for determining a lens type. Background technique [0002] With the rapid development of network and multimedia technologies, a large number of digital videos have emerged, such as news, advertisements, surveillance videos, and home videos. The emergence of a large number of digital videos has led to many new technologies, including video archiving, cataloging, indexing and effective access, etc., and these all need to convert unstructured video data into structured video data. [0003] Video data can be divided into frames, shots, scenes, story units, etc. according to the level. The shot is the basic unit of video structure, so the detection of video shots becomes the basic work of video retrieval and browsing technology. [0004] The automatic recognition of the shooting method of the camera in the video belongs to the description category of ...
