Detection probe, detection equipment and detection method for defects of inner wall of pipeline

The invention relates to the technical field of pipeline inner wall defect detection, in particular to a detection probe, detection equipment and a detection method for pipeline inner wall defects. According to the scheme, the annular light spots emitted by the structured light unit are projected to the inner wall of the pipeline, when the inner wall of the pipeline with the defects exists, the annular light spots deform, and the specific positions and sizes of the defects can be obtained through calibration of the first camera and the second camera and processing of the upper computer. 本发明涉及用于管道内壁缺陷的检测技术领域，尤其涉及用于管道内壁缺陷的检测探头、检测设备及检测方法；该方案中利用结构光单元发出环形光斑投射到管道内壁，当遇到存在缺陷的管道内壁时环形光斑会发生形变，经过第一相机和第二相机的标定以及上位机的处理可以得到缺陷的具体位置与缺陷的大小。
