The quality problem of prefabricated laminated slab (PLS) is one of the important factors that lead to the failure of prefabricated components in construction. The intelligent detection method of PLS can quickly detect the size of PLS, the reserved holes and the location of embedded parts. Basing on machine vision and BIM technology, three PLSs are taken to feature recognition and analysis by intelligent detection method. The results prove that intelligent detection method can be used for image acquisition and image preprocessing of PLS, and the characteristics of the statistics, the size of PLS, the number of holes and size and location information of embedded parts. Intelligent detection method can quickly detect and judge whether the PLS is qualified. Intelligent detection method can improve the pass rate of factory components and reduce the return rate of components, and hence reduce the construction cost and the risk of project delay.
