Systems and methods for detecting tape on a document according to a predetermined sequence using line images

摘要

Systems and methods for detecting tape on a document are provided. In one embodiment, a method includes capturing a first image of a document. The first image is captured while at least a portion of the document is subjected to a first electromagnetic radiation. The method includes capturing a second image of the document. The second image is captured while at least a portion of the document is subjected to a second electromagnetic radiation. The method also includes comparing the first image to the second image to determine whether tape is adhered to the document.

主权项

1. A system for detecting tape on a document, the system comprising:
a document guide for moving the document in a set path; an imaging device for capturing images; a plurality of electromagnetic radiation sources directed toward the document; a controller communicatively coupled to the plurality of electromagnetic radiation sources and the imagining device; wherein the controller includes tape detection application, and wherein the controller running the tape detection application is operable to: capture a first image of a document, the first image captured while at least a portion of the document is subjected to a first of the plurality of electromagnetic radiation sources, capture a second image of the document, the second image captured while at least a portion of the document is subjected to a second of the plurality of electromagnetic radiation sources, comparing the first image to the second image to determine whether tape is adhered to the document; and wherein controller is configured to capture the first image of the document with a first plurality of line images that form the first image, wherein controller is configured to capture the second image of the document with a second plurality of line images that form the second image, and wherein each line image is an image of a vertically spread line of sight of a segment of the document that is less than a whole of the document.
