Detection of Non-XR/MD Detectable Foreign Objects in Meat

A material processing system, comprising:

• a conveyor system having a conveyor belt configured to carry material, the conveyor belt including an outfeed conveyor belt being positioned so that the material will fall through an inspection zone and land on the outfeed conveyor belt;
• and
• an inspection system having:
• a background positioned adjacent the inspection zone;
• and an image capturing device configured to receive electromagnetic radiation (EMR) from the background and from the inspection zone, the inspection zone being configured and arranged to receive material for transport into the inspection zone;
• wherein:
• the background has a background property defined by a background emission, a background absorbance, and a background reflectance, the background property being matched in EMR to a material EMR of a material to be transported into the inspection zone, the material having a material property defined by a material emission, a material absorbance, and a material reflectance;
• the image capturing device is configured to detect a foreign object within material when transported into the inspection zone by deducting the background EMR from the material EMR.

A method for inspection, the method comprising:

• positioning a background adjacent an inspection zone, the background having a background property defined by a background emission, a background absorbance, and a background reflectance;
• directing material of a material flow into the inspection zone, the material having a material property defined by a material emission, a material absorbance, and a material reflectance;
• and
• detecting whether the material property differs from the background property by at least deducting electromagnetic radiation (EMR) of the background from EMR of the material.
