摘　　要：为了有效监控航空发动机磨损故障,经过大量的仿真研究,选择并确定了某航空发动机铁谱磨粒图像的滤波方法;对铁谱彩图的灰度化时的灰度算法进行了合理选择;对基于最大类间方差法Otsu的图像分割算法作了进一步改进,使铁谱磨粒图像中的磨粒与背景能有效分开,同时具有很强的抗干扰性。According to a lot of image filter experiments, median filter was chosen for ferrographic image preprocessing. An algorithm for color image gray processing was reasonably chosen. The ferrographic image segmentation method based on maximum variance between clusters was improved, which makes wear particles of the some engine separated completely from background, and interference immunity is effectively improved.
