Abstract
A method for aligning a tape cartridge accessor with cartridges in cells of a tape cartridge magazine is provided. IR illumination is applied to an object expected to include a desired physical feature. Specular reflections are received from the illuminated object to create an image of the object. Dynamic image thresholding is applied to the image to select an optimum gray scale level of the image expected to include the desired physical feature. Bounding boxes are used to identify the location of the desired physical feature in the thresholded image.

A method for aligning a tape cartridge accessor with cartridges in cells of a tape cartridge magazine, comprising:
- applying IR illumination to an object expected to include a desired physical feature;
- receiving specular reflections from the illuminated object to create an image of the object;
- applying dynamic image thresholding to the image to select an optimum gray scale level of the image expected to include the desired physical feature;
- and
- using bounding boxes to identify the location of the desired physical feature in the thresholded image.
An article of manufacture comprising a program storage medium readable by a computer, the medium tangibly embodying one or more programs of instructions executable by the computer to perform a method for aligning a tape cartridge accessor with cartridges in cells of a tape cartridge magazine, the method comprising:
- applying IR illumination to an object expected to include a desired physical feature;
- receiving specular reflections from the illuminated object to create an image of the object;
- applying dynamic image thresholding to the image to select an optimum gray scale level of the image expected to include the desired physical feature;
- and
- using bounding boxes to identify the location of the desired physical feature in the thresholded image.
