The invention relates to the field of image
data processing, and provides a steam boiler gas leakage detection method based on
image processing, which comprises the following steps: setting an
image acquisition unit, covering a predetermined leakage
risk area together, acquiring corresponding reference images under different production working conditions, and establishing an
image reference library covering a target area; the method comprises the following steps: dividing a boiler
operation time axis into a plurality of production states, calling corresponding reference images according to different states, and carrying out difference, partition comparison and
motion detection on the real-time acquired images to obtain suspected leakage cloud cluster areas in the corresponding states; arranging a condensate water indication patch, collecting a patch image, extracting through color, brightness and texture features to form a patch
humidity change curve, carrying out multi-source
information fusion on the patch
humidity change curve,
time sequence features and production time states, and outputting a corresponding steam leakage
risk level; and generating alarm information according to the steam leakage
risk level, and recording and archiving the alarm information in a monitoring and
management system for
energy consumption analysis and risk tracing.
