Embodiment Construction

[0007] The implementation of the present invention will be specifically described below with reference to the accompanying drawings.

[0008] Such as figure 1 Shown is the flow chart of the flame image recognition method of the present invention, including the following steps: collecting the original image, establishing a flame chromaticity model, removing background information, and detecting suspicious flame areas; according to flame motion characteristics, eliminating static interference, determining the preliminary flame area, Establish a discrete fractal Brownian random field model to eliminate false flames and determine real flame combustion.

[0009] 1. Flame color model and suspicious flame area detection

[0010] The relative positions of pixels of different colors in the flame do have a relatively fixed feature, that is, in the color image of the flame, the bright white area constitutes the core of the flame, which is yellow, orange, and red in sequence from the ins...

Abstract

The invention discloses a method applied to recognition of a flame image generated by gas combustion associated in oil drilling, relating to the field of image processing technologies. According to the color characteristic and the motion characteristic of the flame image, and by combination with discrete fractal Brownian random field, the flame of gas combustion associated in oil drilling is recognized. The method disclosed by the invention can be applied to monitoring the flame of gas combustion gas combustion associated in onshore oil drilling platforms and offshore oil drilling platforms, and also can be used for monitoring the whole safety of the oil drilling platform by combination with an oil-well monitoring system.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for recognizing flame images generated by gas combustion. Background technique [0002] At present, the flame identification methods of associated gas combustion in oil drilling mostly use temperature sensing and photosensitive technologies to identify flames. Due to the variability and uncertainty of flames, these flame identification technologies are subject to the area, humidity, dust particles and These effects are more obvious in the identification of combustion flames of associated gas in oil drilling in harsh environments. In a Chinese patent with a publication number of CN1410709, a method and device for flame monitoring, diagnosis and measurement, only the blackness and chromaticity characteristics of the flame are used as the criterion, and it is not easy to rule out highlighting and moving interference, and it is not suitable for large spaces and bad ...
