Abstract

In order to improve the precision and enlarge the measuring range of Digital Photography Visiometer (DPV) in the daytime, a bi-blackbody algorithm is derived to eliminate the effects of dark current of CCD camera and stray light of background. Some experiments have been performed to compare DPV with one VAISALA FD12 visibility meter and one VIASALA MITRAS Runway Visual Range Assessment System at Luogang Airport, Hefei, in 2002. Plentiful results showed that these instruments work consistently within a reasonable precision when the visibility varies from 50m to 20km. The further experiments proved that DPV with the bi-blackbody algorithm is feasible and reliable at least in the range of 200 times of baseline length.
