High-speed monitoring video quality detection method

Abstract

The invention discloses a high-speed monitoring video quality detection method. The method comprises: stripe detection, blank screen detection, shielding detection, fuzzy detection, brightness detection and chromaticity detection. According to the method, the abnormal phenomena of the image, such as image blurring, image color cast, brightness abnormity, picture shielding and the like, can be detected aiming at the condition of video image quality distortion or degradation. According to the method, the overall quality of the image is improved, the video definition is improved, and technical support is provided for determining a defective video camera, so that relevant maintenance personnel are notified to adjust relevant parameters of abnormal video equipment, and the clearness and integrity of the video image in the expressway are ensured.

Description

technical field

[0001] The invention relates to a high-speed surveillance video quality detection method, which belongs to the technical field of high-speed surveillance video image processing. Background technique

[0002] With the continuous advancement of the road traffic safety prevention and control system, a relatively complete traffic safety prevention and control system has been basically established on the national highway backbone network and national and provincial trunk roads, and the coverage of traffic video surveillance equipment has increased significantly. However, due to system equipment failure and external interference, the video image quality is distorted or degraded, which affects the effective monitoring of road section information by the monitoring system. Therefore, it is necessary to check the image of the desired video to prevent image quality problems caused by unnecessary losses and security risks. The detection of video quality is mainly to det...
