Research on Technologies for Camera Image Defogging in Marine Environment
Aiming at the problems of the low image contrast and poor visibility issues of camera devices in marine fog environments,a single-image fusion-enhanced dehazing technique based on image preprocessing is proposed.Firstly,correction of the atmospheric glow component is conducted.Secondly,combining the characteristics of high transmission rate in the R channel of image sensors,a detail improved image is obtained using wavelet transform and blending.Finally,the guided-filter is used to enhance the image dehazing.The effectiveness and feasibility of the proposed dehazing method are validated through comparative analysis of algorithm processing effects on images collected in actual dense fog environments.
