Method for 3d scanning of a real object

A non-transitory computer-readable data-storage medium containing computer-executable instructions that when executed by a computer system causes the computer system interfaced to a screen and a camera to carry out a method for 3D scanning of a real object with a camera having a 3D position comprising:

• a) receiving, from the camera, an image of the real object;
• b) displaying on a screen, in an augmented reality view, the image of the real object enclosed within a virtual 3D box and, superimposed to the real object, a virtual structure made of a set of planar tiles, and being anchored to the virtual 3D box, each tile corresponding to a predetermined pose of the camera;
• c) detecting that a tile is pointed at with the camera;
• d) acquiring, from the camera, a frame of the virtual 3D box, thereby validating said tile, said frame being a projection of the virtual 3D box on the image;
• iterating steps a) to d) for different 3D positions of the camera, until a sufficient number of tiles is validated for scanning the real object;
• and
• e) implementing a 3D reconstruction algorithm with all captured frames.

A computer system comprising:

• a processor coupled to a memory, a screen and a camera, the memory storing computer-executable instructions for 3D scanning of a real object with a camera having a 3D position that when executed by the processor cause the processor to be configured to:
• a) receive, from the camera, an image of the real object,
• b) display on a screen, in an augmented reality view, the image of the real object enclosed within a virtual 3D box and, superimposed to the real object, a virtual structure made of a set of planar tiles, and being anchored to the virtual 3D box, each tile corresponding to a predetermined pose of the camera,
• c) detect that a tile is pointed at with the camera,
• d) acquire, from the camera, a frame of the virtual 3D box, thereby validating said tile, said frame being a projection of the virtual 3D box on the image,
• iterate a) to d) for different 3D positions of the camera, until a sufficient number of tiles is validated for scanning the real object, and
• e) implement a 3D reconstruction algorithm with all captured frames.
