Therefore, it is a top priority to accurately and quickly detect the cylinder liner surface defects. In order to effectively achieve the classification and localization of surface defects on the cylinder liner, this paper establishes a dataset for surface defects on cylinder liner and proposes a based on improved YOLOv5 algorithm for detecting surface defects on cylinder liner. Firstly, a machine vision system is established to acquire on-site images and perform manual annotation to build the dataset of surface defects on cylinder liner. Secondly, the GSConv SlimNeck mechanism is introduced to reduce the model complexity; the Bi-directional Feature Pyramid Network (BiFPN) is used to fuse the feature information at different scales to enhance the detection accuracy of small surface defects on cylinder liner; and embedding the SimAM attention mechanism to focus on the object region of interest and improve the accuracy and robustness of the model. The final improved YOLOv5 model reduces the number of model parameters by 15.8% compared to the non-improved YOLOv5. And the experimental results on our self-built dataset for cylinder liner defects show that the mAP0.5 is improved by 0.4%. This means that the accuracy of model detection was not compromised. This method can be applied to actual production processes.<\/jats:p>","DOI":"10.3233\/jifs-237793","type":"journal-article","created":{"date-parts":[[2024,3,26]],"date-time":"2024-03-26T12:05:55Z","timestamp":1711454755000},"page":"582-595","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Surface defect detection of cylinder liner based on improved YOLOv5"],"prefix":"10.1177","volume":"49","author":[{"given":"Dai","family":"Jun","sequence":"first","affiliation":[{"name":"School of Mechanical and Power Engineering, Henan Polytechnic University, Jiaozuo, China"},{"name":"Henan International Joint Laboratory of Advanced Electronic Packaging Materials Precision Forming, Henan Polytechnic University, Jiaozuo, China"}]},{"given":"Shi","family":"Huijie","sequence":"additional","affiliation":[{"name":"School of Mechanical and Power Engineering, Henan Polytechnic University, Jiaozuo, China"}]},{"given":"Li","family":"Yanqin","sequence":"additional","affiliation":[{"name":"School of Mechanical and Power Engineering, Henan Polytechnic University, Jiaozuo, China"}]},{"given":"Zhao","family":"Junwei","sequence":"additional","affiliation":[{"name":"School of Mechanical and Power Engineering, Henan Polytechnic University, Jiaozuo, China"}]},{"given":"Hanajima","family":"Naohiko","sequence":"additional","affiliation":[{"name":"College of Information and Systems, Muroran Institute of Technology, Muroran, Japan"}]}],"member":"179","published-online":{"date-parts":[[2024,3,23]]},"reference":[{"key":"e_1_3_2_2_1","first-page":"1","article-title":"Surface defect detection of nonburr cylinder liner based on improved YOLOv4","volume":"2021","author":"Chen Y.","year":"2021","unstructured":"ChenY.FuQ.WangG., Surface defect detection of nonburr cylinder liner based on improved YOLOv4, Mobile Information Systems2021 (2021), 1\u201313.","journal-title":"Mobile Information Systems"},{"key":"e_1_3_2_3_1","doi-asserted-by":"publisher","DOI":"10.14569\/IJACSA.2022.0130818"},{"key":"e_1_3_2_4_1","doi-asserted-by":"crossref","unstructured":"GuoJ.
