| Abstract: | The principle and instrument structure of an opto-electric detection system is presented.The matrix CCD is taken as detection appliance to measure the edge image of contaminated debris.To realize the precise detection,the following technologies are adapted: computer image processing,laser alignment and data processing with combination of optimum threshold partition and outline extraction.The actual hydraulic oil is tested with the system,and the result shows that the system is practical and economical. |
