The invention provides an automobile
oil pump flat
gasket appearance detection method and
system, and belongs to the technical field of automobile part detection. The method comprises the following steps: illuminating through a
light source, acquiring a front multi-angle
image sequence of the flat
gasket, generating a front feature image which highlights defects through fusion
processing, identifying front scratches and notches based on the front feature image, and determining scratch directions and positioning notch geometric parameters; then the flat
gasket is turned over, a reverse side positioning image is obtained, and the gap position offset is calculated; dynamically adjusting
light source parameters according to the offset, and performing enhanced illumination on the gap area on the back side; a reverse multi-angle
image sequence is obtained, a reverse feature image is generated through fusion
processing, and then defect recognition is carried out; and finally generating an appearance detection result by integrating the front and back detection results. Through multi-angle imaging fusion, dynamic
light control based on position offset and direction
perception defect identification, high-precision and full-automatic detection of the appearance defects of the flat gasket is realized, and the detection efficiency and reliability are remarkably improved.
