Systems and methods to create a virtual object or avatar
View Patent ↗A system for generating virtual objects, including personalized avatars. The system comprises modules for acquiring a plurality of series of bi-dimensional images, deriving point clouds and point cloud three-dimensional models therefrom and generating a global point cloud three-dimensional model by computing a weighted average.
1. A system for creating a virtual object, the system comprising:
a) A database comprising at least two series of bi-dimensional images of an object;
b) Non-transitory program code stored in a machine readable medium for execution by a Central Processing Unit (CPU) for:
i) Deriving from the at least two series of bi-dimensional images at least two points clouds, each point cloud corresponding to a set of (x, y, z) points;
ii) Generating from the at least two point clouds at least two point cloud three-dimensional models, each point cloud three-dimensional model comprising a set of (x, y, z) points;
iii) Generating from the at least two point cloud three-dimensional models a global point cloud three-dimensional model, the global point cloud three-dimensional model comprising a set of (x, y, z) points; and
iv) optimizing the global point cloud three-dimensional model, wherein the optimizing comprises minimizing a residue for the property of each point of the global point cloud three-dimensional model, the minimizing of the residue including computing an absolute value of a difference between the property at each point in one of the at least two point clouds and the property at a corresponding point in one of the three-dimensional models.
2. The system of claim 1 , wherein the property is a coordinate.
3. The system of claim 1 , wherein the property is a color.
4. The system of claim 1 , wherein the property is a texture.
5. The system of claim 1 , wherein the property is a perspective.
6. The system of claim 1 , wherein the property is an illumination condition.
7. The system of claim 1 , wherein the at least two series of bi-dimensional images of the object are obtained using a photogrammetry method.
8. The system of claim 1 , wherein the object is a person.
9. The system of claim 8 , wherein the person is wearing close-fitted clothes with motifs to enhance volume deformation.
10. The system of claim 8 , wherein the person is wearing close-fitted clothes with motifs to serve as reference markers to stitch together the bi-dimensional images.
11. The system of claim 8 , wherein the virtual object is an avatar.
12. A method of using the system of claim 1 , comprising using the system for virtual dressing room applications.
