Three-dimensional model generation based on two-dimensional images

A system for generating a three-dimensional (3D) model of an object based on a two-dimensional (2D) image of the object, comprising:

• a database storing a plurality of 3D model templates associating with different types of objects, wherein each 3D model has a plurality of bisectional planes, wherein each bisectional plane comprises a group of 3D control points along the edge of the bisectional plane;
• and
• a 3D model generation engine comprising at least one processor and a memory, the memory storing software instructions that when executed by the at least one processor, causing the at least one processor to perform the following steps:
• selecting a 3D model template from the plurality of 3D model templates based on a type of object appeared in the 2D image;
• determining locations for a plurality of 2D control points on a representation of the object appearing in the 2D image, wherein each 2D control points in the plurality of 2D control points corresponds to a distinct 3D control point;
• and
• modifying the 3D model template by adjusting each bisectional plane based on the determined locations of the plurality of 2D control points on the 2D image;
• obtaining a 2D contour template having an outline of the 3D model and 2D control points located along the outline, wherein each of the 3D control points corresponds to a 3D control point;
• overlaying the 2D image over the 2D contour template;
• and
• adjusting the locations of the 2D control points on the 2D contour template by analyzing a difference between the outline of the object in the 2D contour template and the representation of the object in the 2D image.

A computer-implemented method of generating a three-dimensional (3D) model of an object, comprising:

• obtaining a 3D model having a plurality of bisectional planes, wherein each bisectional plane comprises a group of 3D control points along the edge of the bisectional plane;
• obtaining only one 2D image of the object;
• determining locations for a plurality of 2D control points on a representation of the object appearing in the only one 2D image, wherein each 2D control point in the plurality of 2D control points corresponds to a distinct 3D control point;
• modifying the 3D model by adjusting each bisectional plane only based on the determined locations of the plurality of 2D control points on the only one 2D image;
• obtaining a 2D contour template having an outline of the object and 2D control points located along the outline;
• overlaying the 2D image over the 2D contour template;
• and
• adjusting the locations of the 2D control points on the 2D contour template by analyzing a difference between the outline of the object in the 2D contour template and the representation of the object in the 2D image.
