Abstract
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.
