An electronic apparatus and a method for incremental pose estimation and photographing are provided. In the method, at least two images of a 3D object are captured at different positions encircling the 3D object. Displacements and angular displacements are detected when capturing the images. Features of the 3D object in the images, the displacements and the angular displacements are used to estimate a central position of the 3D object and a distance between the electronic apparatus and the 3D object. A circumference suitable for capturing the images of the 3D object is estimated based on the distance and is divided into several segments, and a timing interval of a timer is adjusted based on a length of the segments. A camera of the electronic apparatus is triggered at intervals set by the timer to capture the images of the 3D object.

Electronic apparatus and method for incremental pose estimation and photographing thereof

A hole filling method for multi-view disparity maps is provided. At least one disparity map is respectively captured as a plurality of known views among a plurality of views for capturing an object. As for a plurality of virtual views among the views excluding the at least one known view, disparity maps of the virtual views are synthesized by sequentially using the disparity maps of the known views according to a distance of a virtual camera position or a transformed angle between each virtual view and each known view. Hole filling information of the disparity maps of other virtual views having the distances or the transformed angles smaller than that of the virtual view is used to fill holes in the synthesized disparity maps of the virtual views.

Hole filling method for multi-view disparity maps

An image processing apparatus includes a determination unit, a search unit, a weight assignment unit and a filling unit. The determination unit determines whether a hole is surrounded by the foreground in a disparity map or a depth map. The search unit searches for multiple relative backgrounds along multiple directions when the hole is surrounded by the foreground. The weight assignment unit respectively assigns weights to the relative backgrounds. The filling unit selects an extremum from the weights, and fills the hole according to the relative background corresponding to the extremum.
