Offshore wind power construction is an important part of China’ s low⁃carbon green strategy.As a mainstream form of offshore wind power infrastructure, the structural quality inspection of offshorewind power super⁃large diameter steel pipe piles plays a vital role in the safety of offshore wind powerinfrastructure. Taking the super⁃large diameter steel pipe piles of offshore wind power as the object, theresearch and application of intelligent detection of steel pipe pile structure quality are implemented. Thelaser scanner was used to obtain the point cloud data of the formed steel pipe pile. Through the steps ofpoint cloud data filtering and noise reduction, point cloud data feature extraction, point cloud dataregistration and fusion, etc., the point cloud data were fitted to generate a three⁃dimensional digitalmodel. Combined with the BIM design model of steel pipe pile, the calculation and analysis were carriedout, and the key structural quality parameters such as the straightness of the pipe pile, the flatness of thepipe end, and the verticality between pipe and pile top flange were obtained,which provides importantsupport for the production quality control of super⁃large diameter steel pipe pile.
