Research on Light Field Distribution and Imaging Effect of Underwater Video Surveillance System
The underwater production system works and operates underwater for a long time,and there will be phenomena such as falling objects anchoring and seabed corrosion,which will lead to the failure of the system,so the deep-sea video monitoring system is researched in order to carry out real-time monitoring of the operation status of the underwater production system.Based on the analysis of the working environment of the deep-sea video monitoring system,combined with the technical indicators of the deep-sea video monitoring system program research.The underwa-ter illumination light field distribution function is established according to the underwater optical characteristics,and the factors affecting the output luminous flux of the illuminator are derived.Considering the luminous flux output of the illuminator required for camera imaging under the effect of visible light scattering underwater,the position distribution of the camera and illumina-tor was determined.By calculating the image contrast and signal-to-noise ratio,the effective ob-servation range of the deep-sea video surveillance system was obtained.Finally,it is confirmed that the best imaging effect is obtained when the angle between the camera and the illuminator is 60°.The results of the study can provide a reference for the design of fixed underwater video long-range panoramic imaging system.
