Research on clarity technology for working face monitoring videos
Aiming at the problem of visual clarity of monitoring video in underground working face,we proposed a dust-proof automatic drainage method for monitoring camera.The hydrophobic coating was used to prepare the camera window,which can effectively reduce the adhesion of coal dust and water mist,and improve the visual monitoring effect of monitoring video screen.In view of the monitoring video image quality degradation caused by dust fog under working condition of working face,a real-time defogging algorithm for monitoring video image was proposed.After real-time defogging,the peak signal-to-noise ratio of the monitoring image was maintained at about 28.2,which makes the feature information of the monitoring image well maintained and enhances the visual effect of the working face monitoring.In the research process of visual distortion correction technology of surveillance video image,a correction method of surveillance video image in working face was proposed,which made full use of the internal feature information of video image and realized the edge distortion correction of surveillance video image without external calibration.Experiments show that the proposed technology can meet the actual production needs to a certain extent and improve the visualization effect of working face monitoring video.
