Electronic apparatus and method for controlling electronic apparatus thereof
An electronic apparatus for acquiring a panorama image using a plurality of cameras and a method for controlling the electronic apparatus thereof are provided. The electronic apparatus includes a plurality of cameras for capturing an image, a sensor for acquiring movement information, and a processor for determining individual movement information of the plurality of cameras with reference to a predefined location using movement information acquired through the sensor, acquiring a plurality of images through the plurality of cameras based on the individual movement information and generating a panorama image using the plurality of photographed images.
1. An electronic apparatus configured to acquire a panorama image, the apparatus comprising:
a plurality of cameras, each configured to capture an image; and
a processor configured to:
acquire a pre-corrected two-dimensional (2D) panorama image using a plurality of images captured by the plurality of cameras;
project the pre-corrected 2D panorama image to a three-dimensional (3D) virtual sphere, determine correction movements of the virtual sphere by analyzing correction movements of a plurality of feature points in the 3D panorama image projected to the virtual sphere;
correct the 3D panorama image based on the correction movements of the virtual sphere; and
acquire a shake-corrected panorama image by re-projecting the corrected 3D panorama image to a corrected 2D panorama image.
2. The apparatus as claimed in claim 1 , wherein the processor is further configured to determine correction movements of the virtual sphere to minimize movement of the plurality of feature points.
3. The apparatus as claimed in claim 1 , wherein the processor is further configured to determine correction movements of the virtual sphere by excluding a feature point that has movement that is greater than or equal to a preset value from among the plurality of feature points.
4. A controlling method of an electronic apparatus to acquire a panorama image, the method comprising:
acquiring a pre-corrected two-dimensional (2D) panorama image using a plurality of images captured by the plurality of cameras;
projecting the pre-corrected 2D panorama image to a three-dimensional (3D) virtual sphere, determine correction movements of the virtual sphere by analyzing correction movements of a plurality of feature points in the 3D panorama image projected to the virtual sphere;
correcting the 3D panorama image based on the correction movements of the virtual sphere; and
acquiring a shake-corrected panorama image by re-projecting the corrected 3D panorama image to a corrected 2D panorama image.
5. The method as claimed in claim 4 , wherein the correcting comprises determining correction movements of the virtual sphere to minimize movement of the plurality of feature points.
6. The method as claimed in claim 4 , wherein the correcting comprises determining correction movements of the virtual sphere by excluding a feature point that has movement that is greater than or equal to a preset value from among the plurality of feature points.
