Embodiment 1

[0030] figure 1 The implementation flow of the multi-channel video splicing method provided by the embodiment of the present invention is shown, and the details are as follows.

[0031] In step S101, the frame memory is divided into multiple storage spaces according to the multi-channel video mosaic method.

[0032] The embodiment of the present invention has multiple video splicing modes. figure 2 , 3 Shows two ways of video splicing, where figure 2 Arranged for left and right, image 3 Arranged up and down. Figure 4 A three-way video splicing method is shown. Figure 5 , 6 A four-way video splicing method is shown. In the embodiment of the present invention, each channel of video may be directly captured by a camera, or stored in various memories, or both.

[0033] Now with Figure 6 The four-way video splicing method shown is taken as an example to describe in detail. The four-way videos are directly captured by cameras a, b, c, and d, respectively, that is, fou...

Embodiment 2

[0041] Figure 7 The architecture of the multi-channel video splicing system provided by the embodiment of the present invention is shown, and the system includes a frame storage control module 1 , a frame memory writing module 2 and a frame memory reading module 3 . Wherein, the frame storage control module 1 is used to divide the frame memory 4 into multiple storage spaces according to the multi-channel video splicing method. The frame memory writing module 2 is used to sequentially write one row of data in each storage space, and so on until all the video data of each channel is written. The frame memory readout module 3 is used to sequentially read the data of each row of the frame memory 4, and display according to the read data. Wherein, each storage space has multiple rows of write addresses.

[0042] In the embodiment of the present invention, the frame storage control module 1 is also used to allocate line buffers to each channel of video, and the system also includ...

Abstract

The invention is applicable to the technical field of video stitching, and provides a method, a system and an electronic device for stitching multiple channels of videos. The method includes dividing a frame memory into a plurality of memory rooms according to a mode for stitching the multiple channels of videos; sequentially writing a row of data into each memory room, and repeating the procedure until all data of the various channels of videos are written into the memory rooms; and sequentially reading the various rows of data in the frame memory and displaying the read data so as to stitch the multiple channels of videos without synchronous trigger. The method, the system and electronic device have the advantages of easiness in control, good synchronization and high image quality.

Description

technical field [0001] The invention belongs to the technical field of video splicing, and in particular relates to a multi-channel video splicing method, system and electronic device. Background technique [0002] The so-called video splicing is to splice two or more videos into one video and output it to a display screen. This splicing technique is an important topic of research in the field of surveillance. In addition, with the development of science and technology, the development of automobile driving record, omni-directional camera, aerospace camera and other fields has also added new catalysts to the research of video stitching, which has promoted the development of video stitching technology and brought new opportunities to video stitching technology. challenge. [0003] In terms of video mosaic research, the traditional video mosaic method is to use a synchronous trigger to drive the video collector at the same time when collecting video, so as to realize the syn...
