Abstract

The invention provides a prevailing visibility automatic observation method and relates to the field of atmosphere detection. A prevailing visibility automatic observation instrument comprises a support frame (5), a light blocking shield (2), a fish eye lens (1), a temperature control box (3), a digital camera (4) and a data processing and control module (6). The top part of the light blocking shield (2) is provided with a fish eye lens installation port which is arranged in the middle part of the top part. The method for utilizing the prevailing visibility automatic observation instrument to carry out automatic observation comprises the following steps of: obtaining a panorama image of an observed area; extracting brightness data of the observed area; extracting object characteristic data of the observed area; with 1 degree used as a unit, calculating an object visibility value in each sector range; and outputting a prevailing visibility value. The prevailing visibility automatic observation method has the advantages that the automatic observation of the prevailing visibility is firstly realized; the functions of a whole-sky nephometer are also available; the visibility values of the whole surface are obtained; and a function of observing effective horizontal visibility is also realized.

Description

technical field [0001] The invention relates to the field of atmospheric detection, in particular to an automatic observation method for dominant visibility. Background technique [0002] Predominant visibility is of great significance to civil aviation operations. The "visibility" usually referred to in civil aviation operations refers to the prevailing visibility. Dominant visibility is used in many aspects such as airport minimum operating standards, minimum flight planning standards, and operational classification standards for precision approach and landing. Accurate observation of prevailing visibility is of great significance for normal takeoff and landing of aircraft. In the current industry, the observation of this value is completely manual observation. Although manual observation dominates visibility, it is easy to achieve full-angle 360-degree observation, but this method is easily affected by many factors. Different observers have different understandings of...
