Embodiment Construction

[0019] In order to describe the technical solutions of the present invention in detail, the following describes in detail in conjunction with specific implementation methods and accompanying drawings.

[0020] The overall system structure of the panoramic video monitoring scheme facing the large scene proposed by the present invention can be found in figure 1 . The monitoring solution includes large-scale monitoring devices and large-scale monitoring systems.

[0021] The large scene monitoring device includes a front-end video acquisition module, a video encoding module and a data sending module.

[0022] The front-end video acquisition module is a video acquisition device encapsulated in a transparent spherical glass cover, consisting of a horizontal scale and four specific cameras. It is used to obtain the original video sequence of the front-end monitoring area, and transmit it to the video encoding module for video encoding respectively. The horizontal scale marks the ...

Abstract

The invention provides a panoramic video monitoring method and device orienting large-scale scenes. The device comprises front end video capture coding equipment and data transmission equipment. A large-scale scene monitoring system comprises software and hardware of data acceptance, video decoding, video processing, output coding and the like. The method finishes the steps of video data acceptation, video decoding, video registering, GPU real-time splicing and color fusing. Panoramic monitoring image sequences obtained through splicing fusion are continuously output to display equipment through an HDMI/DVI for displaying; meanwhile, real-time coding of a panoramic monitoring image is supported, and transmission and storage are carried out through a network. According to the method and the device, the splicing effect and the splicing quality of panoramic videos can be ensured, the efficiency of video splicing is improved, the real-time demand is met, and the obtained panoramic videos are natural and real. In actual application, the requirement of follow-up panoramic video splicing can be well ensured, installation arrangement of site equipment can be simplified, and the implementation is high.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a method and device for panoramic video monitoring of large scenes. Background technique [0002] In recent years, with the development of the social situation, the significance of video surveillance is self-evident, and its application has become more and more extensive, and various monitoring devices and systems with special functions and for different application scenarios have emerged. However, real-time video surveillance suitable for large scenes with urgent monitoring needs is relatively rare. Such as large squares, large event sites, crossroads, etc., security personnel not only need to clearly see the details of a certain corner, but also need to grasp the overall situation of the large scene and the main track of the main body of the activity at a glance. For the application scenarios of large scenes, if the traditional multi-camera monitoring system is used, ...
