Thus, it is critical to carry out precise measurements on the key component surface to evaluate the stress concentration. Based on white-light interferometry (WLI), we studied the measurement distortion caused by the reflected light from the steep side of the grinding groove being unable to return to the optical system for imaging. A threshold value was set to eliminate the distorted measurement points, and the cubic spline algorithm was used to interpolate the eliminated points for compensation. The compensation result agrees well with the atomic force microscope (AFM) measurement result. However, for residues on the surface, a practical method was established to obtain a microscopic 3D micro-topography point cloud and a super-depth-of-field fusion image simultaneously. Afterward, the semantic segmentation network U-net was adopted to identify the residues in the super-depth-of-field fusion image and achieved a recognition accuracy of 91.06% for residual identification. Residual feature information, including height, position, and size, was obtained by integrating the information from point clouds and super-depth-of-field fusion images. This work can provide foundational data to study surface stress concentration.<\/jats:p>","DOI":"10.3390\/s23198307","type":"journal-article","created":{"date-parts":[[2023,10,9]],"date-time":"2023-10-09T06:16:48Z","timestamp":1696832208000},"page":"8307","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["A Micro-Topography Measurement and Compensation Method for the Key Component Surface Based on White-Light Interferometry"],"prefix":"10.3390","volume":"23","author":[{"given":"Junying","family":"Chen","sequence":"first","affiliation":[{"name":"College of Marine Equipment and Mechanical Engineering, Jimei University, Xiamen 361000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Boxuan","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Marine Equipment and Mechanical Engineering, Jimei University, Xiamen 361000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3296-1642","authenticated-orcid":false,"given":"Xiuyu","family":"Chen","sequence":"additional","affiliation":[{"name":"College of Marine Equipment and Mechanical Engineering, Jimei University, Xiamen 361000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6775-5171","authenticated-orcid":false,"given":"Qingshan","family":"Jiang","sequence":"additional","affiliation":[{"name":"College of Marine Equipment and Mechanical Engineering, Jimei University, Xiamen 361000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Feng","sequence":"additional","affiliation":[{"name":"College of Marine Equipment and Mechanical Engineering, Jimei University, Xiamen 361000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhilong","family":"Xu","sequence":"additional","affiliation":[{"name":"College of Marine Equipment and Mechanical Engineering, Jimei University, Xiamen 361000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenye","family":"Zhao","sequence":"additional","affiliation":[{"name":"College of Marine Equipment and Mechanical Engineering, Jimei University, Xiamen 361000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"109605","DOI":"10.1016\/j.ymssp.2022.109605","article-title":"A review of vibration-based gear wear monitoring and prediction techniques","volume":"182","author":"Feng","year":"2023","journal-title":"Mech.
