1. A method implemented on a computing device including a storage device and at least one processor for positioning an object positioned on a table, the method comprising:
obtaining a plan image, the plan image illustrating a virtual surface of the object and a virtual surface of the table;
determining a target position of the table based on the virtual surface of the table;
obtaining, by one or more capture devices, a 3-dimensional (3D) image, the 3D image including a first set of elements corresponding to the object and a second set of elements corresponding to the table;
generating an augmented reality image by projecting the virtual surface of the table onto the 3D image;
displaying the augmented reality image on a display device;
determining a current position of the table based on the 3D image; and
causing the table to move based on the current position and the target position of the table.
