Abstract:Theexposed partof thelightsteelcorecolumninsulationsandwichcomposite masonry wallisprone towalldamage duetonaturalfactors,whichafectstheservicelifeof thewall.Therefore,aninfraredthermal imagingdetectionmethodfor damage ofcomposite masonrywalsisproposed.Thismethodusesultrasonicinfraredthermal imaging technologytoobtain infraredimagesof damagetocompositemasonrywals,filteringoutpixelsbelowtheoptimalthreshold.Basedonthebilateral filteringmethod,Basedonimageprocesing technologyandmorphologicaldetectiontechnology,accurateextractionofdamaged edges ncompositemasonrywalsiscarriedouttodeterminetheseverityof thedamageandachieve precise detection.The results showedthatwhenthenumberof images was 2Oto10O,the mAPvalue and recallratedetectedbyour method were both higher than 90.00% . The wall damage detection was relatively complete and the damage branches were obvious, which intuitively demonstrated the detection effect;The accuracy is higher than 95.00% ,which improves the completeness of the wall damage detection method; The average IoU is higher than 85.00% ,effectively improving the overlap rate between the damaged area and the calibration area. This method has good detection effect and high detection performance.
