Abstract

The invention discloses a wear particle surface reconstruction method based on a multi-focus image and a related device. The method comprises the following steps: acquiring a multi-focus image sequence of wear particles to be reconstructed; determining a division parameter corresponding to the multi-focus image sequence by adopting a differential evolution algorithm, and performing region division on each focus image in the multi-focus image sequence based on the division parameter to obtain a plurality of image blocks corresponding to each focus image; calculating the focus degree value of each image block obtained by division, and fusing the multi-focus image sequence based on the focus degree value of each image block to obtain a fused image; and determining a depth value of each pixel point in the fused image to obtain a reconstructed image corresponding to the wear particles to be reconstructed. According to the embodiment, the division parameters corresponding to the multi-focus image sequence are determined through the differential evolution algorithm, and the fused image block is selected based on the focus degree value of each image block obtained through division, so that the focus degree of the fused image block can be improved, and the definition of the reconstructed image can be improved.

Description

technical field [0001] The present application relates to the technical field of biological friction and wear, in particular to a multi-focus image-based method for reconstructing the surface of wear particles and related devices. Background technique [0002] Wear particles include ferromagnetic abrasive grains, non-ferrous metal abrasive grains, and ceramic shavings, which are commonly found in the fields of mechanical friction and biological tribology. The research on wear particles is very common in these fields. For example, in the field of mechanical friction, online sensors are usually installed on the equipment to monitor the oil state in the continuous circulation lubrication system in real time. The detection of wear particles in the oil is very important for judging mechanical failures and Abnormal wear states are of great significance. In the field of biotribology, the research on wear particles is also often reported. For example, in the application research of...
