Claim:
1. A system for mitigating glare while reading printed information tags located in an enclosed environment using multi-pose illumination, comprising: a shelf imager, the shelf imager for acquiring shelf images for printed information tag localization and recognition; a printed information tag locator and recognizer analyzing all or a portion of acquired images to localize and recognize printed information tags; an external illuminator, the external illuminator for providing at least one illumination condition for shelf image acquisition in addition to lighting associated with the enclosed environment, said external illuminator further comprises a multi-pose external illuminator, and wherein the multi-pose external illuminator provides different illumination conditions by varying positions of the multi-pose external illuminator around the shelf imager and onto the shelf, wherein the order of imaging of the poses of the multi-pose external illuminator for image capture is determined based on image analysis of previously acquired shelf images; and a glare region of interest (ROI) detector, said glare region of interest (ROI) detector for analyzing at least a portion of the acquired shelf images for glare to determine whether additional images of the shelf images need to be acquired for recognition using a different illumination condition provided by the external illuminator.
