Problems solved by technology
However, there is a problem of discontinuous trajectories between different cameras of the panoramic camera in the panoramic video shot by the panoramic camera. If the existing video enrichment technology is used directly, there is a problem of tracking the motion trajectory of the same moving object into multiple motion trajectories of multiple moving objects. problem, so that the condensed video does not match the original video, which affects the accuracy of panoramic video condensing

Embodiments of the present application provide a panoramic video concentration method, device, device, and storage medium. The method includes: acquiring the preselected motion trajectories of each preselected moving object in the first video, where the preselected motion trajectories of each preselected moving object pass through the position corresponding to the dividing line, and the first video is obtained after the panoramic video is divided by the dividing line According to the pre-selected motion trajectories of each pre-selected moving object, the motion characteristics of each pre-selected moving object passing through the position are obtained, and according to the motion characteristics, the pre-selected motion trajectories corresponding to the same moving object are combined to obtain the combined motion trajectory; according to the motion characteristics The combined motion trajectory is used to obtain the condensed video of the panoramic video. The technical solution provided by the embodiments of the present application avoids the problem of tracking the motion trajectory of the same moving object as multiple motion trajectories of multiple moving objects during the process of panoramic video concentration, and improves the accuracy of panoramic video concentration.
Description
technical field [0001] The present application relates to the technical field of video surveillance, and in particular to a method, device, equipment and storage medium for panoramic video concentration. Background technique [0002] With the rapid development of computer network and digital video technology, video surveillance based on digital network is widely used in security applications of public places and important facilities, such as banking, electric power, transportation, security inspection and military and other fields. With the increasing scope of security monitoring, the number of monitoring equipment is also increasing at an alarming rate, which in turn produces a large amount of surveillance video, which mainly has the characteristics of large amount of video storage data, long storage period, and large storage space. The traditional method of searching for clues by manually checking videos requires a lot of manpower, material resources and time, and the effi...
