Other AbstractIn the field of electro-optical imaging,polarization filtering is one of the significant technologies to reject airlight to improve imaging quality,with a prerequisite of analyzing and computing the polarization degree of airlight under condition of near-horizontal observation.In this case,utilizing the classical Rayleigh scattering theory and Wilkie skylight polarization model to compute the polarization degree of airlight resulted in larger error.Therefore,by modifying Wilkie skylight polarization model,a computational model for the polarization degree of airlight under condition of near-horizontal observation was developed in this paper.The inputs of this model contained the latitude and longitude of an observation site,date and time of observation,direction of observation and atmospheric visibility.Experiments indicate that this model can provide more accurate results than both the Rayleigh scattering theory and the Wilkie skylight polarization model under condition of near-horizontal observation.Moreover the influence of extinction ratio on measurement error for the polarization degree of airlight was analyzed. 更多
