Paper Abstract

For improving the measurement accuracy of aviation part’s profile, a high-accuracy profile measurement method based on step boundary model is proposed in this paper. Firstly, the cases of light stripe imaging in the target boundary are analysed, and the corresponding ideal boundary models are built to determine the ideal boundary locations. Then, a subpixel boundary extraction method based on feature moment is presented, which can obtain sub-pixel boundary locations on the basis of the crude boundary detection. Next, based on the reconstruction algorithms, the profile of aviation part is measured. At last, experiments using a standard part are conducted to verify the accuracy of this method and a measurement experiment is carried to verify the effectiveness of the boundary extraction. Experiment results show that the presented method can achieve the object boundary extraction in complex background interference and light environment. The extraction method can reach an accuracy of 0.056% and satisfy the requirements of field measurement.
