一种建筑外立面缺陷视觉检测方法及系统
By acquiring the video stream of the building facade, selecting key frame images, estimating the camera pose and fitting the facade plane, establishing a bidirectional mapping between pixels and surface coordinate grids, and performing intrinsic image decomposition and evidence adjudication, the problem of false alarms and missed alarms in the detection of defects in building facades is solved, and verifiable defect detection and coordinate localization are realized.

Abstract
本发明涉及计算机视觉与智能检测技术领域，具体涉及一种建筑外立面缺陷视觉检测方法及系统，其方法包括：获取外立面视频流并筛选关键帧；基于关键帧估计相机位姿并拟合外立面平面，建立外立面表面坐标栅格及像素与栅格的双向映射；对关键帧执行内禀图像分解得到反射率图像与光照图像，基于反射率图像提取缺陷候选区域，基于光照图像生成阴影反证信息与高光反证信息并构建表面证据场；基于表面证据场进行证据累计与反证裁决得到确认候选，并选取反事实验证帧对确认候选复核，输出缺陷类型与外立面表面坐标定位信息。本发明在复杂光照与视角变化下实现可验证的缺陷检测并降低误报。
