Imaging module with aligned imaging systems

摘要

An imaging module including a plurality of imaging systems for capturing images of a receiver medium. An illumination system illuminates the receiver medium with an illumination pattern. First and second imaging systems are positioned to capture images of the receiver medium, each including at least a portion of the illumination pattern. The first and second images are analyzed to determine a relative position of the illumination pattern in the first and second images. Imaging system alignment parameters for use in aligning images captured with the first and second imaging systems are determined responsive to the determined relative position.

1. An imaging module including a plurality of imaging systems for capturing images of a receiver medium, comprising:
an illumination system for illuminating the receiver medium with light providing an illumination pattern; a first imaging system positioned to capture an image of at least a portion of the receiver medium, the first imaging system having a field-of-view that includes at least a portion of the illumination pattern; a second imaging system positioned to capture an image of at least a portion of the receiver medium, the second imaging system having a field-of-view that includes at least a portion of the illumination pattern; a data processing system; and a program memory communicatively connected to the data processing system and storing instructions configured to cause the data processing system to implement a method for aligning the first and second imaging systems, wherein the method includes:
using the first imaging system to capture a first image of the receiver medium, the first image including at least a portion of the illumination pattern;using the second imaging system to capture a second image of the receiver medium, the second image including at least a portion of the illumination pattern;analyzing the captured first and second images to determine a relative position of the illumination pattern in the first and second images;determining one or more imaging system alignment parameters responsive to the determined relative position; andstoring the determined imaging system alignment parameters in a processor-accessible memory for subsequent use in aligning images captured with the first imaging system with images captured with the second imaging system.
