摘　　要：在实际检测高层建筑外墙时,往往受场地条件限制易造成拍摄仰角过大,局部识别误判、漏判等。为进一步解决建筑外墙检测,特别是高层建筑外墙检测中遇到的困难,不断提升检测方法的适用性、准确性和可靠度,文章利用无人机搭载红外热像仪、数码相机进行了初步研究,并对在仰角过大时正常拍摄及采用无人机搭载红外热像仪拍摄下的结果进行对比分析,结果表明,利用无人机优势,可以解决场地限制造成的仰角问题,但无人机本身的稳定性等问题有待技术进步进一步解决。When it comes to real detection of exterior wall of high buildings,problems such as shooting at a higher angle,misleading partial judge and omitted partial judge are frequently occurred.In order to over the odds of exterior wall detection of building,especially the obstacles encountered in the exterior wall detection of higher buildings,and to increasingly improve the application,accuracy and reliability of the detection methods,this paper carries out an elementary research on thermal infrared imagery and digital cameras installed on unmanned aerial vehicle.It also proceeds with a comparative analysis on how to shoot at a right angle when the angle is too high,and on the results delivered by thermal infrared imager installed on the unmanned aerial vehicle.The results show that the problem of tilt angle caused by venue restrictions can be overcome by employing the advantages of unmanned aerial vehicle.Nevertheless,it is to be solved by technology advancement for the stability of the unmanned aerial vehicle.
