SYSTEM FOR EVALUATING AGRICULTURAL MATERIAL
First Claim
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.

Abstract
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.

10. A system for evaluating performance of an imaging system, the system comprising:
-
an imaging device for collecting a set of images that relate to agricultural material in a passage; a controller coupled to the imaging device, the controller comprising; a data port for receiving the set of images from the imaging device, a diagnostic module comprising instructions stored on a data storage device, an electronic data processor arranged to execute the instructions associated with the diagnostic module, wherein execution of the diagnostic module causes the controller to perform a method comprising; determining an average image of the set of images; obtaining a last image of the set of images; determining a difference between the average image and the last image to create a differenced image; eliminating background image data from the differenced image to produce an initial image mask of unchanged content identified 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. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
