The invention discloses a construction quality control method based on a BIM point cloud technology and three-dimensional scanning in the field of building construction measurement. The construction quality control method includes a three-dimensional laser scanner, wherein the three-dimensional laser scanner directly carries out laser scanning on an internal structure of a building or carries outlaser scanning on a high-rise structure of the building through a flight carrier or a bionic robot; and a receiver on the three-dimensional laser scanner receives the three-dimensional point cloud data to determine building structure information, comprehensively receives the three-dimensional point cloud data to establish a unified three-dimensional coordinate system, generates a unified point cloud model, and imports the unified point cloud model into three-dimensional software to compare and analyze the unified point cloud model with an ideal three-dimensional model of building design. The construction quality control method has the advantages of being easy to operate, high in automation degree and complete in coverage range.
