1. An inspecting and sorting apparatus comprising:
a product stream formed of a plurality of individual objects of interest each having a feature aspect which can be detected and the product stream is passed along a predetermined path;
a background positioned at a known position relative to the predetermined path;
a plurality of detection devices, each of the plurality of detection devices is positioned at a known position relative to the background and relative to the predetermined path, each of the detection devices are capable of being actuated and when actuated, each of the detection devices generate a device signal, and the known position of each of the plurality of detection devices, relative to the predetermined path and relative to the background, provides a known, and different, perspective field of view of the predetermined path; and wherein a portion of each known, perspective field of view of each of the plurality of detection devices, is common to at least one other of the plurality of detection devices;
multiple images of the individual objects of interest are generated by the plurality of detection devices, each of the generated multiple images have a different perspective of the individual objects of interest and a real-time time-stamp is assigned to each of the generated multiple images;
every detectable feature aspect of each of the individual objects of interest is classified as being either a parent feature, which is a single object of interest, or a child feature, which is a detectable feature aspect of the respective parent feature or single object of interest;
a complementary region of each of the generated multiple images of the respective individual objects of interest is identified by analyzing at least some of the previously classified parent features and/or child features identified in the generated multiple images;
some of the generated images are fused together using the identified complementary regions of the generated multiple images and using the assigned real-time time-stamps so as to form a resulting aggregated region representation of individual objects of interest; and
the respective individual objects of interest in the product stream are sorted based, at least in part, upon the aggregated region representation.
