Abstract
An approach is provided for automatically recommending ground control points or any other feature points for image correction (e.g., satellite image correction). The approach, for example, involves collecting a plurality of images depicting a geographic area of interest. The approach also involves processing the plurality of images to detect one or more candidate feature points (e.g., ground control points or other features detectable in the images). The approach further involves performing a feature correspondence of the one or more candidate feature points across the plurality of images. The approach also involves triangulating respective locations of the one or more candidate feature points based on the feature correspondence. The approach further involves filtering the one or more candidate feature points based on the respective locations. The approach further involves providing the filtered one or more candidate feature points as an output comprising one or more recommended feature points.
