Method and device for playing monitoring video

Abstract

Embodiments of the invention provide a method and a device for playing a monitoring video. The method comprises the following steps: receiving first input information of a user, wherein the first input information is used for selecting a target area from a video image of the monitoring video; determining whether a moving object exists in the target area; if no moving object exists in the target area, fast forwarding the monitoring video; and if the moving object exists in the target area, determining a play speed of the monitoring video according to the speed of the moving object in the target area, and playing the monitoring video at the play speed. In the method and the device provided by the embodiments of the invention, the target area is selected according to the input information of the user, the video image of the input information focused by the user can be located quickly, the play speed of the monitoring video is determined according to the speed of the object in the target area, the play speed of the monitoring video can be matched with the speed of the object, and the check effect of the monitoring video is improved.

Description

technical field [0001] The present invention relates to the field of video playback, and more specifically, to a method and device for playing surveillance video Background technique [0002] In the field of video surveillance, when the surveillance video is played back, the general focus is on valuable dynamic images, but in fact the surveillance video usually contains a large number of static images without motion information. Therefore, when the surveillance video is played back, it is often necessary to drag or Adjust the speed of playback to find dynamic pictures. However, these playback methods are relatively cumbersome to operate and have low efficiency, and it is easy to miss the dynamic picture of interest. [0003] In order to solve the above problems, the existing technology detects the speed of multiple objects in the surveillance video screen to obtain the average speed of the multiple objects, and then determines the playback speed of the surveillance video ac...

Problems solved by technology

However, this playback method only controls the playback speed of the video according to the average speed of the objects in the picture, and the control accuracy is not high, and it is impossible to control the playback speed of the video according to the speed of a single object. When the object is moving, the movement information of the object of interest cannot be well viewed
