METHOD FOR OBTAINING LIGHT-FIELD DATA USING A NON-LIGHT-FIELD IMAGING DEVICE, CORRESPONDING DEVICE, COMPUTER PROGRAM PRODUCT AND NON-TRANSITORY COMPUTER-READABLE CARRIER MEDIUM

摘要

It is proposed a method for obtaining light field data of a scene from a sequence of images of the scene, each image being captured at a different viewpoint using a non-light-field image capture device. The method comprises:
- obtaining (110) a reference image of the scene at a reference viewpoint, an interest area of the scene being comprised in the reference image and a reference position (x 0 ,y 0 ) being associated with said interest area in a reference local coordinate system of said capture device;
- for a current image of the scene at a current viewpoint:
- identifying (120) said interest area of the scene in the current image;
- determining (130), in the reference local coordinate system, a current position (x c ,y c ) of said interest area identified in the current image;
- comparing (140) the current position with the reference position;
- providing (150) a capture guidance indicator adapted to guide in relative positioning of the capture device towards the interest area, as a function of results of the comparison between the current position and the reference position.
