1. A method for performing inspections of product instances during a production process, the method comprising:
providing a product conveyor configured to move the product instances through the production process;
positioning a plurality of cameras at different locations along the product conveyor, wherein each camera of the plurality of cameras has an associated field of view;
for each camera of the plurality of cameras, determining a difference in location along an axis parallel to a direction of travel of the product conveyor of a field of view of the each camera relative to a field of view of view of another of the plurality of cameras;
for each camera of the plurality of cameras, capturing images of product instances as the product instances pass through the camera's field of view on the conveyor;
associating each of a plurality of images captured by different ones of the cameras as being images of a same product instance;
based on one or more of the plurality of images of the same product instance, making a determination to reject the same product instance;
determining that the same product instance has reached a rejection location along the product conveyor; and
taking action to reject the same product instance at the rejection location.
