The dimensions of ring forgings can be analyzed by the point cloud data of ring forgings scanned by laser. The dimensions are the key to evaluating the parameters of ring forgings. Due to the limitation of the scanning angle of the laser scanner, the complete data of the radial section line for the ring forging cannot be obtained through one scan. So the point cloud data of multiple scans are stitched to get the complete data of radial section line. In response to the stitching question, a point cloud data stitching method for ring forgings is proposed in this study. Firstly, the coarse stitching is carried out by using the relationship between the center coordinates of the two data sets. Then, the repeated region is found by the improved Beetle Antennae Search Algorithm (BASA). The repeated region is divided into three parts to find corresponding points in the process of precise stitching. The complete radial section line data can be obtained. Finally, the stitched radial section line is transformed into a complete 3D ring forging model. The comparison experiment results show that the algorithm proposed in this study is simple and fast. The accuracy of this algorithm is verified by extracting the dimensions of the complete model for ring forging.
