The invention provides an aircraft appearance defect screening method, and relates to the field of aircraft appearance detection. The aircraft appearance defect screening method comprises the following steps of S1, moving a small carrier to the vicinity of an aircraft through a preset route, S2, scanning the vicinity through a laser radar to obtain the relative position and the position of the aircraft, S3, generating an inspection route, performing inspection camera shooting, and automatically adjusting the camera shooting angle, the light intensity, the automatic distance measurement and the focal length of a camera during the inspection, s4, loading X-rays and infrared rays, penetrating metal flaw detection cracks and analyzing temperature abnormity, and S5, analyzing and processing a shot picture, transmitting and displaying a changed part to a worker to check and analyze whether a defect exists or not. The carrier is matched with the high-definition camera on the mechanical arm to realize automatic inspection and screening of airplane appearance problems, time and labor are saved, inspection is more careful and accurate, the error rate is lower, and meanwhile, acquired images are optimized and compared, so that the influence of objective factors is smaller.

    本发明提供了一种飞机外观缺陷筛查方法,涉及飞机外观检测领域。该飞机外观缺陷筛查方法,包括以下步骤,S1:小型载具通过预设路线移动至飞机附近,S2:通过激光雷达对附近进行扫描,得到飞机相对位置和自身位置,S3:生成巡检路线,进行巡检摄像,其间自行调节摄像角度、灯光强度、自动测距及相机焦距,S4:加载X光和红外线,透过金属探伤裂纹和分析温度异常,S5:对摄像后的照片进行分析处理,将变化部位传输显示给工作人员查看,分析是否存在缺陷。通过载具配合机械手臂上的高清相机实现飞机外观问题的自动巡检筛查,省时省力的同时检查更加仔细精准,错误率更低,同时对采集图像进行优化对比,受客观因素的影响更小。
