Abstract

The invention relates to a real-time detecting method of horizontal visibility level. A device is composed of a fixing target object, an image collecting unit, a background processing equipment, a storage unit, a foreground processing unit, a wireless communication module and an information receiving terminal, the image collecting unit and the storage unit are connected with the background processing equipment, the image collecting unit, the storage unit and the wireless communication module are connected with the foreground processing unit, and the wireless communication module and the information receiving terminal are in wireless signal connection. The processing method comprises a background processing equipment processing method and a foreground processing unit real-time processing method. By means of the method, accurate horizontal visibility measuring can be achieved, and the method can be applied to the fields of airports, harbors, bridges, roads, railways, environmental protection, meteorological station and the like.

Description

technical field [0001] The invention relates to the field of digital image processing, in particular to a real-time horizontal visibility level detection method. Background technique [0002] The level of horizontal visibility is inseparable from people's production and life. Visibility is a physical quantity affected by many components. Its definition also varies in different application fields. There is no formal measurement of it in various countries. Calibration standards and testing rules. At present, the performance and measurement results of many visibility measurement devices are obtained from the analysis of a large number of previous scholars' test statistics. Therefore, it is one of the difficulties to be solved urgently to have a complete and unified set of visibility measurement criteria. Visibility measurement methods now mainly include visual inspection methods, instrument measurement methods, and visibility detection methods based on image features. With th...

Problems solved by technology

Visibility measurement methods now mainly include visual inspection methods, instrument measurement methods, and visibility detection methods based on image features. With the evolution of intelligent life, in view of the current high cost of visibility measurement instruments and difficulties in equipment maintenance, consider from the existing environmental intelligence. It is feasible to obtain the corresponding pictures in the device to measure the visibility, so the visibility detection based on the image has become a main direction, but due to the complexity of the environment, such as terrain, buildings, moving objects and other factors, the visibility detection It is still in the stage of theory and experiment

At present, most of the detection algorithms are based on the research of simple environments such as highways. The scope of application of this algorithm is relatively small, and at the same time, the complexity is high, and the operation is relatively complicated.
