| Abstract: | Aiming at the requirement of oil real-time analysis system application, various factors affecting the performance of the whole sampling oil analysis system based on microscopical images are analyzed,and some important advanced methods are proposed.And then an analytical system of the oil contamination based on the separating flow sampling principle is developed.Based on the characteristics of the practical system,the method for identifying particles having image motion characteristics and auto threshold value selection is put forward and the velocity distribution is analyzed in the flow field.The problem of computing contamination classes is solved,and fine results are achieved in experiments as compared with conventional instruments. |
| Keywords: | oil contamination analysis photographic measurement separating flow sampling particle identification contamination class computation |
