Abstract

A circuit breaker circular opening and closing indicating lamp image noise filtering method relates to the technical field of power systems, and comprises the following steps: setting a rectangular opening and closing identification area in a circuit breaker circular opening and closing indicating lamp image, and carrying out gray processing on the image in the opening and closing identification area to obtain a gray-scale map; and performing layer-by-layer filtering on the gray scale from the center point of the grey-scale map by adopting an iteration method in combination with the adjacent gray scale average value and the annular gray scale average value so as to remove relatively large noise pollution in the grey-scale map, and taking the grey-scale map obtained after filtering as an opening and closing state recognition image of the circular opening and closing indicator lamp of the circuit breaker. The method provided by the invention is used for identifying the opening and closing state of the circular opening and closing indicator lamp of the circuit breaker in an auxiliary monitoring system of a substation.

Description

technical field [0001] The invention relates to the technology of electric power system, in particular to the technology of a method for filtering the image noise of the circuit breaker circular opening and closing indicator light. Background technique [0002] In the substation auxiliary monitoring system, it is often necessary to identify the circular opening and closing indicator lights of the circuit breaker in the video image to assist in judging whether the opening and closing of the circuit breaker is in place, from a single comprehensive automatic signal monitoring mode to a variety of signal Mutual verification mode, this kind of recognition of the image indicator light can improve the monitoring reliability and accident analysis level. [0003] In the daily operating environment, the image of the circular opening and closing indicator light of the circuit breaker will cause image noise due to the influence of ambient light, which leads to low recognition accuracy o...
