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

The embodiment of the invention provides an image processing method and device, equipment and a system. The method comprises the following steps: caching each path of video picture to be spliced to one sub-display picture respectively, and caching a video picture to be spliced in each sub-display picture to the same total display surface; and displaying the video picture in the total display surface in a display window. Through adoption of the image processing method, only one video picture in the display surface is displayed specific to the display window, namely, the display window only displays one path of video picture instead of displaying a plurality of paths of video pictures, so that the splicing gaps are avoided, and the display effect is 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...
