Abstract
A computer-implemented method for surface modeling includes: receiving one or more polarization raw frames of a surface of a physical object, the polarization raw frames being captured with a polarizing filter at different linear polarization angles; extracting one or more first tensors in one or more polarization representation spaces from the polarization raw frames; and detecting a surface characteristic of the surface of the physical object based on the one or more first tensors in the one or more polarization representation spaces.
Claims26
A computer-implemented method for surface modeling, the method comprising:
- receiving one or more polarization raw frames of a surface of a physical object, the polarization raw frames being captured at different polarizations by a polarization camera comprising a polarizing filter;
- extracting one or more first tensors in one or more polarization representation spaces from the polarization raw frames;
- and
- detecting a surface characteristic of the surface of the physical object based on the one or more first tensors in the one or more polarization representation spaces.
A system for surface modeling, the system comprising:
- a polarization camera comprising a polarizing filter, the polarization camera being configured to capture polarization raw frames at different polarizations;
- and
- a processing system comprising a processor and memory storing instructions that, when executed by the processor, cause the processor to:
- receive one or more polarization raw frames of a surface of a physical object, the polarization raw frames corresponding to different polarizations of light;
- extract one or more first tensors in one or more polarization representation spaces from the polarization raw frames;
- and
- detect a surface characteristic of the surface of the physical object based on the one or more first tensors in the one or more polarization representation spaces.
