摘   要 ：輕鋼芯柱－保溫夾層組合砌體墻的裸露部分受自然因素影響易出現墻體損傷，影響墻體的使用壽命，為此提出組合砌體墻損傷紅外熱像檢測方法。該方法通過超聲紅外熱成像技術，獲取組合砌體墻損傷的紅外圖像，基于雙邊濾波方法，提升了組合砌體墻損傷圖像的低照度；基于圖像處理技術和形態學檢測技術，對組合砌體墻損傷邊緣進行精準提取，確定損傷程度 ，實現精確檢測。結果表明： 當圖像數量為 20 ~ 100 張時，該方法檢測的 mAP 值與召回率均高于 90. 00% ,  墻體損傷檢測較為完整且損傷支線明顯，直觀表現了檢測效果； 準確度均高于 95. 00% ,  提升了墻體損傷檢測方法的檢測完整度；平均 IoU 均高于 85. 00% ,  有效提高了損傷區域與標定區域之間的重疊率。該方法的檢測效果好、性能高。

Abstract: The exposed part of the light steel core column insulation sandwich composite masonry wall is prone to wall damage due to natural factors, which affects the service life of the wall. Therefore, an infrared thermal imaging detection method for damage of composite masonry walls is proposed. This method uses ultrasonic infrared thermal imaging technology to obtain infrared images of damage to composite masonry walls, filtering out pixels below the optimal threshold. Based on the bilateral filtering method, Based on image processing technology and morphological detection technology, accurate extraction of damaged edges in composite masonry walls is carried out to determine the severity of the damage and achieve precise detection. The results showed that when the number of images was between 20 and 100, the mAP value and recall rate detected by our 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.
