First Claim
1. An electronic system, comprisingcircuitry configured toobtain a sequence of frames of an object under different viewing angles,process the sequence of frames, wherein the circuitry for processing the sequence of frames is further configured toreceive preconditioned frames,for each preconditioned frame, extract salient image points, wherein the salient image points identify small image areas of high contrast,reduce a total number of salient image points by selecting only a predetermined number of stable salient image points, andgenerate, for a first time instance, a point cloud descriptive for an external surface of the object based on (i) a point cloud obtained for a second time instance preceding the first time instance and (ii) disparity information concerning a frame captured at the first time instance,display a 3D representation of the point cloud generated for the first time instance, andupdate the displayed 3D representation while obtaining the sequence of frames.

Abstract
An electronic system includes a circuitry configured to obtain a sequence of frames of an object under different viewing angles at consecutive time instances. For a first time instance, the circuitry generates a point cloud descriptive for an external surface of the object on basis of (i) a point cloud obtained for a second time instance preceding the first time instance and (ii) disparity information concerning a frame captured at the first time instance.

10. A 3D reconstruction method, comprising
capturing a sequence of frames of an object under different viewing angles at consecutive time instances; -
processing the sequence of frames, wherein processing the sequence of frames includes receiving preconditioned frames; for each preconditioned frame, extracting salient image points, wherein the salient image points identify small image areas of high contrast; reducing a total number of salient image points by selecting only a predetermined number of stable salient image points; and generating, for a first time instance, a point cloud descriptive for an external surface of the object based on (i) a point cloud obtained for second time instance preceding the first time instance and (ii) disparity information concerning a frame captured at the first time instance; displaying a 3D representation of the point cloud generated for the first time instance; and updating the displayed 3D representation while capturing the sequence of frames. - View Dependent Claims (11, 12)
