Abstract

The invention provides a switching method and device for a video. The method comprises the following steps of collecting video images of a plurality of regions; respectively carrying out face recognition on each video image to detect the current state of the region; determining the priority of playing the video images according to the regions and the current state; and switching the video image with the highest priority to a display picture. According to the method and the device, the priority ranking is carried out according to the different states in each video image and the display picture is switched according to the priority, so that a function of automatic conducting of multi-channel videos is realized.

Description

technical field [0001] The present invention relates to the field, in particular to a video switching method and device. Background technique [0002] In the prior art, in some shooting occasions, in order to achieve the characteristics of multi-angle and multi-view, it is necessary to perform multi-channel video shooting, that is, multiple cameras shoot video at the same time. The director in charge of video switching selects one video from multiple channels and plays it on the main screen. [0003] Multi-channel video directing often requires dedicated directing personnel to operate. On the one hand, this takes up manpower, and on the other hand, it also limits the use of multi-channel shooting. If there are fewer staff or no professionals who know how to direct, multi-channel shooting cannot be performed. [0004] There is no ideal solution in the industry at present for the problem that the video guidance operation in the prior art is relatively complicated. Contents...
