SYSTEM FOR EVALUATING AGRICULTURAL MATERIAL

摘要

Disclosed herein is a diagnostic module configured to determine an average image of a set or a sequence of collected images, to obtain a last image of the set or the sequence of collected images, and to determine a difference between the average image and the last image to yield a differenced image. Background image data or background pixels are eliminated from the differenced image to produce an initial image mask of unchanged content in the last image. A diagnostic module or data processor determines a mask area of the initial image mask or a revised image mask derived from the initial image mask. A diagnostic module or data processor generates an alert data message to inspect or clean the imaging system if the mask area exceeds a threshold area.

1. A method for evaluating performance of an imaging system, the method comprising:
collecting a set of images that relate to agricultural material in a passage; determining an average image of the set of collected images; identifying a last image in the set of collected images; determining a difference between the average image and the last image to yield a differenced image; eliminating background image data from the differenced image to produce an initial image mask of unchanged content in the last image; determining a mask area of the initial image mask; and generating an alert data message to inspect the imaging system if the mask area exceeds a threshold area.
