摘要: A system for inspecting cylinders according to various aspects of the present invention generally includes a roller assembly comprising a plurality of rollers configured to hold the cylinder. A light source illuminates the cylinder and a camera produces an image of at least a portion of the cylinder as the roller assembly rotates the cylinder about its longitudinal axis. A computer system is configured to control the roller assembly, light source, and camera and analyze the image to identify a defect associated with the cylinder.

摘要: A system and method for inspecting stents can involve an inspection camera to take an image of the stent and a computer system for analyzing the image to determine the presence of any coating defects. The determination can be made by masking out a portion of the stent, identifying deviations from a strut edge, and/or highlighting features protruding from a stent external boundary defining an outer diameter. The image can be taken after a focus feedback camera determines the position of the stent.
