The invention discloses a multi-input-video fusion processing method and device. The method comprises the following steps of: A, obtaining video information, and carrying out format conversion of videos; B, rotating and translating the video images, so as to fuse a plurality of videos into a wide-field-of-view image; C, performing image filtering enhancement processing on the videos; and D, performing zooming and frame rate improvement processing on the image data, and outputting a video. The beneficial effects of the method and the device are that a video image fusion unit generates an address and writes the address into a fixed data packet, a post-processing subsystem scales the image information and is also used for improving the image frame frequency, and therefore, the problem that atraditional multi-video fusion technology generally adopts a multi-channel fusion mode and a multi-channel and independent storage mode, so that block scheduling and random read-write of memory resources are easily caused, and processor and memory resource waste is caused is solved.
Description
Technical field[0001]The invention relates to the field of video fusion processing, in particular to a method and device for multi-input video fusion processing, and belongs to the technical field of video fusion processing.Background technique[0002]Video fusion technology is a branch of virtual reality technology, which can also be said to be a development stage of virtual reality. Video fusion technology refers to the combination of one or more image sequences of a scene or model collected by video capture equipment with a Related virtual scenes are merged to generate a new virtual scene or model about this scene. In this model, because of the addition of video, a combination of information that cannot be completed by the virtual scene or the video itself is obtained. The purpose of video fusion It is to increase the interaction between the virtual scene and reality, reduce the information uncertainty in the computer model, increase the information carrying capacity of the virtual...
