摘要： Disclosed herein is a method of producing a polyurethane foam block (137') using a foam production machine (100) for producing polyurethane foam as a slabstock (137) The method comprises: mixing (800) the precursor reagents in a mixing head (102) to provide a reactive mixture; dispensing (802) the reactive mixture; receiving (804) the reactive mixture by a conveyor (106); cutting (806) the polyurethane foam block from the slabstock to produce a cut surface (724) with a foam cell structure (906); acquiring (808) a digital image (742) of the cut surface; inputting (810) the digital image into a trained machine learning module (762, 1000, 1200), the trained machine learning module being trained to produce a two-dimensional segmentation (1012) of the foam cell structure for the prediction of a foam parameter (744); and signaling (812) the foam parameter in response to inputting the digital image into the trained machine learning module.
