The emergent light formed by the light source of the laser scanning component 40 is linear, and the projection surface of the emergent light is perpendicular to the axis of the pipeline 60 to be detected. The laser scanning assembly 40 is a commercially available line laser tester and thus its structure will not be explained further.
Through turning into point light source into the line source, detect traditional sampling formula and detect and change for continuous type and detect, reduced the error that whole pipeline detected. The distance from the outer surface of the pipeline 60 to be detected to the laser detector is obtained, after continuous sampling, the outer surface profile model of the whole pipeline 60 to be detected is obtained, and whether the out-of-roundness and the surface defects of the pipeline 60 to be detected meet the regulations or not is judged, so that the pipeline detection efficiency can be greatly improved, and the detection error is reduced.
