Embodiment approach

[0139] 1. Preset the position information of the cropping area corresponding to each acquisition device, so that each acquisition device can crop the image it collects to obtain the image to be spliced.

[0140] by figure 2 For example, it is possible to set the position information of the clipping area corresponding to the capture device 1 as the position information of the overlapping area 1, set the position information of the clipping area corresponding to the capture device 2 as the position information of the overlapping area 2, and set the capture device The location information of the clipping area corresponding to 3 is the location information of the overlapping area 3.

[0141] Alternatively, it is also possible to set the position information of the clipping area corresponding to the acquisition device 2 as the position information of the overlapped area 1, set the position information of the cropping area corresponding to the acquisition device 3 as the position i...

Abstract

An embodiment of the present invention provides an image processing method, device, device, and system. The method includes: first buffering each video image to be spliced ​​in a sub-display surface, and then buffering the video images to be spliced ​​in each sub-display surface to the same total display surface; the video image in the total display surface is displayed in the display window; in this way, for the display window, what is displayed is a video image in the display surface, which is equivalent to the display window for one channel of video The image is displayed, and the display processing will not be performed in the manner of displaying multiple video images, so there will be no splicing gaps, and the display effect will be improved.

Description

technical field [0001] The present invention relates to the technical field of video monitoring, in particular to an image processing method, device, equipment and system. Background technique [0002] In the process of video surveillance, it is usually necessary to display multiple videos on the same screen, so that multiple scenes can be monitored at the same time. In the existing solutions, the various videos are usually spliced ​​and displayed according to the positional relationship of the scenes displayed by the various videos. [0003] Specifically, a display area may be defined for each camera in the display device according to the positional relationship of each camera, and these display areas form a complete display window. For each camera, the video it collects is played in its corresponding display area, so that what is displayed in the display window is the spliced ​​picture of each channel of video. [0004] However, for the display window, if multiple channe...
