Three-dimensional object reconstruction

A computation unit for creating a three-dimensional reconstruction from a single two-dimensional image, the computation unit comprising:

• a memory;
• and
• at least one processor, wherein at least one processor is configured to perform operations comprising:
• receiving a two-dimensional image;
• identifying an object in the image to be reconstructed and identifying a type of said object;
• spatially anchoring a pre-determined set of object landmarks within the image;
• extracting a two-dimensional image representation from each object landmark;
• estimating a respective three-dimensional representation for the respective two-dimensional image representations;
• and
• combining the respective three-dimensional representations resulting in a fused three-dimensional representation of the object.

A computer readable medium that stores a set of instructions that is executable by at least one processor of a computation unit for creating a three-dimensional reconstruction from a single two-dimensional image to cause the computation unit to perform operations comprising:

• receiving a two-dimensional image;
• identifying an object in the image to be reconstructed and identifying a type of said object;
• spatially anchoring a pre-determined set of object landmarks within the image;
• extracting a two-dimensional image representation from each object landmark;
• estimating a respective three-dimensional representation for the respective two-dimensional image representations;
• and
• combining the respective three-dimensional representations resulting in a fused three-dimensional representation of the object.

A method for updating a fused three-dimensional representation of an object comprised in a two-dimensional image, the method comprising:

• projecting the fused three-dimensional representation on to a two-dimensional image plane resulting in a projected representation;
• comparing respective positions of the projected representation with the object in the two-dimensional image;
• determining an error value based on the comparing;
• and
• adjusting parameters of the fused three-dimensional representation based on the error value, wherein the comparing, measuring and adjusting are iterated until the measured error value is below a predetermined threshold value or a threshold number of iterations is surpassed.
