Systems and methods for locating a retroreflective object in a digital image

A system comprising:

• a first image acquisition device to acquire at least a first image with light emitted from an illuminator;
• a second image acquisition device to acquire at least a second image without or with less of the light emitted from the illuminator;
• a memory to store at least the first image and the second image;
• a processor to:
• generate a compound image from the first image and the second image;
• align content of the first image and the second image prior to generating the compound image;
• and
• locate an object in the compound image.

A method comprising:

• activating an illuminator to emit light, and acquiring a first image from a first image acquisition device with light emitted from the illuminator;
• acquiring a second image from a second image acquisition device without or with less of the light emitted from the illuminator;
• generating a compound image from the first image and the second image;
• aligning content of the first image and the second image prior to generating the compound image;
• and
• locating an object in the compound image.
