The average tuna cannery produces about 500,000 cans per day, but only a small fraction of these cans are inspected for defects, flake percentage and top appearance. Visual inspection is labour intensive and prone to human error and bias.
For that reason, we’ve been working on building new algorithms for TallyVision, our smart camera for automated inspection. First, TallyVision can now count cans (up to 4 cans per second!) coming from packing machines to provide you with data on uptime and downtime or OEE (Overall Equipment Effectiveness). A live viewer even enables you to watch the packing line from the comfort of your office.
We’re now working on computer vision algorithms to detect defects, classify the top appearance and even estimate the flake percentage of cans. The latter is especially important since it can have a big impact on the drained weights of cans.
