Real-time wide-scene monitoring synthesis method for cloud data center room

Abstract

The invention provides a real-time wide-scene monitoring synthesis method for a cloud data center room, which synthesizes a monitoring video into a wide-scene wide-angle video in real time by arranging two common cameras in a cloud data center room in the following steps: (1) carrying out a camera calibration and correction method; (2) matching key frames; and (3) carrying out a fusion method and a real-time wide-scene video synthesis method. The camera calibration and correction method (1) is characterized in that the inner parameter, the outer parameter and the distortion parameter of the camera are calibrated and corrected with a common checkerboard method in the computer visual domain to favorably correct the distortion of the camera; and a result is more scientific, objective and real; in the camera calibration and correction method which is the first step of the method, a calibration algorithm based on a plurality of free planes of Open computer vision (CV) is adopted, i.e. a 7*7 checkerboard image is held by hands, and the length and the width of each check are both 2cm; the checkerboard image is translated and rotated in front of a pickup camera to obtain images of different directions; and when enough images (at least 10 pieces) are collected, the inner parameter, the outer parameter and the distortion parameter of the pickup camera are obtained by a pickup camera calibration function of the Open CV so as to correct the frame image.

Description

technical field [0001] The invention relates to the field of computer applications, in particular to a real-time wide-scene monitoring and synthesis method for a computer room of a cloud data center. Background technique [0002] With the development of information technology, cloud computing has gradually become a hot spot in the industry, and cloud computing service platforms of major manufacturers at home and abroad have also begun to invest in science, education, culture, health, government, high-performance computing, e-commerce, and the Internet of Things. used in many fields. [0003] In order to ensure the safety of machinery and equipment, monitoring systems are installed in the computer rooms of most cloud computing data centers. However, due to limitations in hardware and other aspects, the viewing angle of each camera in the monitoring system is limited, and only a small part of the computer room can be captured, and video information of a larger area cannot be ...
