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.
