Patent ID: 10165254

Abstract:
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 is described. The method includes obtaining a reference image of the scene at a reference viewpoint, an interest area of the scene being included in the reference image and a reference position (x0,y0) being associated with the interest area in a reference local coordinate system of the capture device. For a current image of the scene at a current viewpoint, the method identifies the interest area of the scene in the current image, determines, in the reference local coordinate system, a current position (xc,yc) of the interest area identified in the current image, compares the current position with the reference position and provides 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.
