| Abstract: | Considering that the cost of traditional hazemeters are expensive, a new method of detection of visibility is researched based on dark channel prior. Transmission can be estimated by the dark channel prior and refined by Guided Fil- ter. Extinction coefficient can be obtained by the transmission, so visibility can be calculated. Experimental results show that this method is credible and can be applied in practice. |
