| titleOfInvention | Oil particle detection method based on image processing |
| abstract | The invention provides an oil particle detection method based on image processing, which comprises the steps of S1, acquiring an oil image; s2, controlling the oil working pump to work, and cleaning an oil pipeline and detecting particles; s3, preprocessing the image; s4, every time the frame number of the oil liquid image reaches N b Carrying out background modeling for one time; s5, obtaining a candidate particle binary image of the current oil image according to the background and the background threshold value; s6, performing mathematical morphology operation on the binary image; s7, intercepting each candidate particle image, and performing primary screening; s8, calculating a gradient image of each candidate particle image in the current oil image in the S5; carrying out block statistics on the obtained data; calculating the average gray value of the edges of the particles; s9, acquiring a binary image of the candidate particle image in the current oil image in S5; s10, identifying the particle type of the particles; s11, calculating the relative diameter of the particles; and S12, generating an oil detection analysis report. The method can improve the accuracy of particle detection. |
