With the progress of economy and science and technology in recent years, overhead lines in transmission lines have gradually been replaced by high-voltage cables. Because the cable tunnel is an underground closed equipment, the staff can not intuitively observe the situation in the cable tunnel in real time, and can only rely on the cable tunnel image transmitted by the monitoring system in real time for online monitoring, and the environment in the cable tunnel is complex, the air is not circulating, and it is very easy to produce fog, which is extremely unfavorable to the image transmitted by the monitoring system in real time. In this paper, the contrast is optimized by the method of image enhancement to achieve the purpose of dehazing the cable tunnel image and make the image clearer.
