Cylindrical surfaces of three-dimensional Inspection
Accurate Inspection of Randomly , Oriented Cylindrical Surfaces , Cylindrical surfaces of three-dimensional products such as bottles, vials and cosmetic containers are difficult to inspect. Cameras often cannot be placed in the ideal locations, the part may have unknown orientation, or the surface to inspect may span multiple camera views. The OmniView Cylindrical Product Inspection System solves these problems. This system uses images acquired from one or more cameras, and combines those images to create a seamless and undistorted image of an object surface. As long as a feature of interest appears in one or more of the physical camera images, it can be inspected. OmniView completely eliminates the complex and expensive requirement to mechanically spin parts in order to inspect them. This reduces production line complexity, lowers costs, and increases production speed. OmniView even compensates for rotation, tilt, uneven lighting, and perspective distortion ... the factory floor problems that exist in the manufacturing process.
Applications
The OmniView system facilitates traceability and performs
extensive product quality checks on cylindrical food, beverage,
pharmaceutical, and many other products. Packaging flexibility,
food safety, productivity, and quality control all benefit from
the simplified 360-degree product inspection. Here are some
of the many OmniView applications and benefits:
• Confirming package/product match ... lowering the risk
of a recall
• Reducing scrap … by detecting wrong or mislabeled
products early in the production process
• Checking for torn or missing labels…critical to the
packaging process
• Reading 1D and 2D codes…enables products to be
tracked and traced through manufacturing
• Verifying label printing integrity … to ensure a positive
brand image on store shelves
• Detecting damaged products … that result from
operations such as cartoning
• Checking date code presence … ensuring that an inkjet
printer is functioning properly
• Performing date/lot code OCR and OCV … verifies that
product information is correctly printed and that labels are
placed onto the right products
• Checking for roundness … for enhanced brand image
• Gauging … without a telecentric lens
