Problems solved by technology
However, this method of configuration limits the combination of the main picture channel and the sub-picture channel, making the picture-in-picture channel combination limited to the combination of static settings, so it is difficult to achieve dynamic superimposition of multi-channel pictures
[0004] At present, no effective solution has been proposed for the problem that it is difficult to realize the dynamic superimposition of multi-channel images in related technologies

The invention relates to a picture superposition processing method, device and system, an electronic device and a storage medium, and the processing method comprises the steps: obtaining a monitoring equipment queue in the same monitoring scene; receiving an event triggering instruction, and obtaining at least one triggering event matched with the event triggering instruction; when it is detected that at least one target monitoring device containing the trigger event exists in the monitoring device queue, obtaining a target main picture based on the target monitoring device and the trigger event, and obtaining at least one target sub-picture based on the trigger event; and performing synthesis processing on the target main picture and the at least one target sub-picture so as to obtain a picture superposition result. According to the invention, the problem that it is difficult to achieve mutual dynamic superposition of multi-channel pictures is solved, and flexible picture superposition combined display is achieved.
Description
technical field [0001] The present application relates to the technical field of picture-in-picture, and in particular to a processing method, device, system, electronic device and storage medium for superimposing pictures. Background technique [0002] At present, the picture-in-picture technology in the monitoring field is to use the audio and video codec technology to superimpose the streams of multiple channels into a new stream output and display it on the screen. When displaying half screen, you need to check other multiple screens. [0003] In related technologies, the main picture channel and sub-picture channel are usually specified through page configuration. This channel can be an analog camera channel or a digital camera channel, and all channels can be superimposed on each other. If they are all digital camera channels, they need to be decoded at the same time. Audio and video are synthesized, if there is an analog channel, just specify the channel. However, t...
