Food glorious food
This webcast will cover three case studies of vision technology used in food production. These include two instances of hyperspectral inspection, one for determining the quality of fish as they pass down a conveyor fresh from the boat, while the other considers how hyperspectral imaging can be used to inspect strawberries for bruising. A third case study looks at a machine for removing apple cores using 3D vision to guide the knife.

Hyperspectral imaging in the fish industry Hyperspectral imaging is emerging as an important tool in the fish industry. Several applications that have been explored by researchers for years are finally finding their way to the production line. In this presentation we will give an overview of the challenges in the fish industry where hyperspectral imaging has been investigated as a solution. Te focus will be on detection of blood content and parasite detection. We will also go through the technical requirements for the different applications when it comes to spectral and spatial resolution, depth of measurement, and measurement speed.

Apple coring system using 3D vision Te solution was developed to automate the removal of apple cores and thus increase productivity and reduce the rejection rate in production. Te system is based on 3D vision by Photoneo - the PhoXi 3D scanner - that is able to recognise and localise the position and orientation of apple cores, and guide the cutting machine to remove them. Te scanner provides high resolution and accuracy of 3D reconstruction, and also a large scanning range that means eight apples can be processed at a time, with a cycle time of less than one second.

Inspecting strawberries for bruising with hyperspectral imaging Mechanical handling can bruise fruit during harvest, transport, and storage. Te bruises lower the quality and cause significant economic losses because such produce easily ferments, rots, or gets mildew and infects other produce during storage. By using hyperspectral imaging and Perception Park software it is possible to make the invisible visible with a non-destructive technique for quality control. Perception Park software is designed to analyse data from any hyperspectral camera and prepare it for machine vision applications. Perception Park software and a Specim FX17 hyperspectral camera were used to detect and colour-code bruises on strawberries.
