1. A computer-implemented method comprising:
tracking by photogrammetry, a food-product unit during a food-processing operation to identify one or more first borders of the food-product unit, the one or more first borders including two or more points, and identify, based on a changed distance between the two or more points of the one or more first borders that exceeds a threshold distance, separation of a food-product subunit from the food-product unit;
determining by the photogrammetry, a first volume of the food-product unit and a second volume of the food-product subunit;
generating a code for the food-product subunit, the code comprising a first identifier for the food-product unit and a second identifier for the food-product subunit,
wherein the first identifier is based, at least in part, on the first volume,
wherein the second identifier is based, at least in part, on the second volume; and
assigning the code to the food-product subunit.
