The axial section line of the ring forging is the key parameter to measure whether the ring forging process meets the technical requirements. To ensure the quality of the ring forgings, an online measuring method of the axial section line in ring forging process is proposed in this study. First, the axial section line data of the ring forging is obtained online by laser scanning device. Then, the axial section line data is locally sorted and is screened to eliminate the edge noise. Second, the axial section line data is converted to line grey image data by merger and derivation theory. Finally, the line grey image data is smoothed by bilateral filtering based on information entropy selection factor. Then, the shape of the axial section line is constructed to complete the measurement of the axial section line. The experimental results show that the measurement speed of axial section line meets the requirements and the measurement accuracy of the axial section line meets the requirements.
