Abstract
Provided is a method for adjusting lubrication optimization of a marine main engine cylinder based on computer vision, and belongs to the technical field of marine power systems. The method includes: establishing a marine main engine lubrication database for cylinder lubrication analysis and quality evaluation; collecting cylinder lubrication data of each current cylinder, and preprocessing cylinder lubrication image set data; performing image segmentation and cluster analysis on the preprocessed cylinder lubrication image set, and comparing the preprocessed cylinder lubrication image set with the marine main engine lubrication database to obtain feature recognition results of carbon deposition, dirts, scratches and a wear degree; and according to the feature recognition results, evaluating a cylinder lubrication quality to obtain evaluation grades, and adjusting cylinder lubrication optimization according to the evaluation grades.
