Zusammenfassung:The invention relates to the technical field of non-contact three-dimensional scanning, in particular to a point cloud data splicing method and system based on structured light, and can solve the problem that errors exist between three-dimensional point cloud data obtained based on a precision module carrying line laser sensor and real point cloud data to a certain extent. The point cloud data splicing method based on the structured light comprises the following steps: projecting the structured light to a local area of a measured object for multiple times; a plurality of local structured light images of a first view field and a second view field are obtained, the view field where the measured object is located is divided into the first view field and the second view field, and an overlapping part exists between the first view field and the second view field; and when the local structured light images acquired from the first field of view and the second field of view can form a complete structured light image
