To decode an optical pattern in a real scene, an optical pattern is detected in one or more images acquired by a camera, a distance from the optical pattern to the camera is estimated, the distance from the optical pattern to the camera is compared to a threshold value, acquiring an image of the optical pattern, down sampling the image, based on the distance from the optical pattern to the camera being less than the threshold value, to generate a down-sampled image, and the optical pattern is decoded in the down-sampled image.

Image analysis for scanning optical patterns in a real scene at dynamic ranges

An angled optical pattern is decoded. To decode an optical pattern imaged at an angle, an area of interest of an image is received. A start line and an end line of the optical pattern are estimated. Corners of the optical pattern are localized. A homography is calculated based on the corners. And a scanline of the optical pattern is rectified based on the homography.
