Methods and Apparatuses of Detecting Foreign Particles or Faults in a Plurality of Filled Containers |
摘要 |
A method of detecting unwanted objects or faults in containers containing a fluid or liquid includes: (a) moving the containers along a path of travel; (b) providing; a light source emitting light of a specific spectral distribution, wherein the containers and their contents are at least partly transparent or translucent at the specific spectral distribution; (c) providing a camera for detecting light at the specific spectral distribution, wherein (1) the path of travel intersects a field of view defined by the camera, and (2) the camera registers a sequence of digital images as the containers pass between the light source and the camera; (d) selecting a part of each of the digital images that corresponds to the outline of a specific container; and (e) processing a sequence of the parts of the digital images so as to detect the unwanted objects or faults in the specific container.
