Body part imaging method
First Claim
1. A method of imaging an object, the method comprising the steps of,disposing the object in front of a surface having patterned areas and a reference area, the object providing an object image, the object being disposed in front of the patterned areas for obstructing patterned images of the pattern areas positioned relative to the reference area providing an unobstructed reference image, focusing a camera upon the object, upon the patterned areas, and upon the reference areas from differing perspectives at respective perspective positions for capturing respective composite images each comprising the object image, the patterned images and the reference image, generating a data stream of the composite image comprising X rows and Y columns of an array of pixels, the data stream providing a series of transitions indicating regularity of the patterned images, a duration between each of the transitions indicating a number of pixels along one of the X rows and Y columns of the array of pixels, area determining along one of the rows or columns of the array of pixels the number of pixels between each of the transitions for determining an interruption in regularity of number of pixels between each of the transitions for indicating where the object obstructs the patterned areas at an obstructed pattern area of one of the patterned areas for indirectly indicating the 2D edge point of the object, and determining a distance between the reference area and obstructed patterned area for determining the 2D edge point of the object relative to the reference area.

Abstract
An imaging method places an object upon a background pattern of regular repetitive marks and records a 2D image that is then processed for determining where in the image the repetitive marks are interrupted by the object, thereby indirectly determining the edge of the object. Multiple 2D images from different perspectives are used to create a 3D image of the object. When the object is a human food, individual bar codes and imaged foot dimensions can be cross-referenced to manufactured shoe sizes for accurate ordering of correctly sized footwear.

1. A method of imaging an object, the method comprising the steps of,
disposing the object in front of a surface having patterned areas and a reference area, the object providing an object image, the object being disposed in front of the patterned areas for obstructing patterned images of the pattern areas positioned relative to the reference area providing an unobstructed reference image, focusing a camera upon the object, upon the patterned areas, and upon the reference areas from differing perspectives at respective perspective positions for capturing respective composite images each comprising the object image, the patterned images and the reference image, generating a data stream of the composite image comprising X rows and Y columns of an array of pixels, the data stream providing a series of transitions indicating regularity of the patterned images, a duration between each of the transitions indicating a number of pixels along one of the X rows and Y columns of the array of pixels, area determining along one of the rows or columns of the array of pixels the number of pixels between each of the transitions for determining an interruption in regularity of number of pixels between each of the transitions for indicating where the object obstructs the patterned areas at an obstructed pattern area of one of the patterned areas for indirectly indicating the 2D edge point of the object, and determining a distance between the reference area and obstructed patterned area for determining the 2D edge point of the object relative to the reference area.
