Abstract: Disclosed are various embodiments for determining a pose of a mobile device by analyzing a digital image captured by at least one imaging device to identify a plurality of regions in a fiducial marker indicative of a pose of the mobile device. A fiducial marker may comprise a circle-of-dots pattern, the circle-of-dots pattern comprising an arrangement of dots of varied sizes. The pose of the mobile device may be used to generate a three-dimensional reconstruction of an item subject to a scan via the mobile device.
