STEREOSCOPIC FORM READER

摘要

A stereoscopic optical reader of a form example is provided where two images are captured of the same scene on a known form example taken from two different angles. The stereoscopic images are amenable to parallax calculations that may help determine that the form example is flat. If the two captured images are congruent with each other and/or with a stored digital model of the form, the entire form example may be read. If the images are not congruent, the form may be rejected as not being flat, and/or the image data may be further processed via parallax operations and/or other such projections to yield a virtual flat form.
