Abstract
Image capture methods and systems with positioning and angling assistance are provided. A reference image having a first set of feature points is provided. A preview image is captured and analyzed using a feature detecting algorithm to obtain a second set of feature points. A variation is calculated according to the first set of the feature points corresponding to the reference image and the second set of the feature points corresponding to the preview image, and a present-marker is rendered on a display unit according to a preset position and the variation.
