Video quality diagnosing method

Abstract

The invention relates to the technical field of video analysis and discloses a video quality diagnosing method comprising the steps as follows: step 101,video data coming from a remote camera to be diagnosed are obtained by a transmission server; and step 102, indexes of the video data are detected in a preset time range, and a diagnosis result is provided, wherein the step 101 and the step 102 are conducted in an asynchronous way, the video data are detected after a certain quantity of video data is cached, and the video quality is diagnosed according to the detection result. The effective video quality diagnosing method is realized by the designed methods on detecting the indexes of image definition, video loss rate, picture partial chromaticity, picture gain imbalances degrees, contrast, picture upheaval, screen freezes degrees, screen wobble degrees, stable stripe interference degrees, horizontal grain superposition degrees and noise degrees of the video data.

Description

technical field

[0001] The invention relates to the technical field of video analysis, in particular to a video quality diagnosis method. Background technique

[0002] The most important feature of the security system is stability and reliability. The video surveillance system is the most important part of the security surveillance system. After an alarm occurs, the reliable availability of video information is the basic requirement of the video surveillance system. In view of the fact that manual detection is laborious and laborious, it is almost impossible in a large system. Therefore, it is an inevitable requirement for the security system to intelligently and automatically detect the quality of the system video on a regular basis, and it will even become a necessary module of the platform software in the future.

[0003] Using the video quality diagnosis system, users can effectively prevent image quality problems and losses caused by video acquisition equipment, video t...
