Abstract
Systems and methods for aligning panoramic imagery of a geographic area captured from a perspective at or near ground level and aerial imagery captured from an oblique perspective are provided. More particularly, a facade plane can be detected in a panoramic image based at least in part on geometric data associated with the image. The panoramic image can also have an associated image pose. An aerial image depicting the same facade can then be identified. The aerial image can be associated with an image pose and geometric data of the depicted imagery. The panoramic image can be warped into an image having a perspective associated with the aerial image. One or more feature matches between the warped image and the aerial image can be identified using a feature matching technique. The matched features can be used to align the panoramic image with the aerial image.
