Abstract
One embodiment of a system and method for imaging items may include storing at least one lookup table that includes position data of multiple image regions, where the position data provides relative positions of the image regions. An item may be moved to pass through the image regions. Image data of the item may be imaged as the item passes through a plurality of the image regions. The position data may be applied to the captured respective image data from each of the image regions through which the item passed to form a set of stitching image data that is substantially aligned with one another. The set of stitching image data may be stitched to form a composite image of the item.
Claims20
A system for imaging items, said system comprising:
- a camera including a plurality of imaging pixels;
- at least one optical element configured and positioned to cause at least two subsets of the imaging pixels to capture respective image regions;
- a conveyer belt configured to move an item in front of said camera;
- a non-transitory memory configured to store at least one lookup table that includes position data of the image regions, the position data providing relative positions of the image regions;
- a processing unit in communication with said camera and said non-transitory memory, and configured to:
- capture image data of an item from each of the subsets of imaging pixels;
- apply the position data to the captured respective image data from each of the respective subsets of imaging pixels to form a set of stitching image data that is substantially aligned with one another;
- and
- stitch the set of stitching image data to form a composite image of the item.
A method for imaging items, said method comprising:
- storing at least one lookup table that includes position data of multiple image regions, the position data providing relative positions of the image regions;
- moving an item to pass through the image regions;
- capturing image data of the item as the item passes through a plurality of the image regions;
- applying the position data to the captured respective image data from each of the image regions through which the item passed to form a set of stitching image data that is substantially aligned with one another;
- and
- stitching the set of stitching image data to form a composite image of the item.
