• To accurately characterize reflected light fields from 3D objects illuminated by specific light fields.
• To establish a unified radiometric representation for light field intensity and BRDF.

Main Methods:

• Developed a light field reflection matrix (LFRM) model.
• Integrated a bidirectional reflectance distribution function (BRDF) model for isotropic materials.
• Established a radiometric characterization model for plane-sphere light fields.
• Constructed a matrix computation model for light-field rendering.

Main Results:

• The LFRM model effectively characterizes reflected light fields.
• A unified radiometric representation for light intensity and BRDF was achieved.
• The matrix computation model enabled efficient light-field rendering.
• Simulation experiments validated the model's effectiveness.

Conclusions:

• The proposed LFRM model provides a comprehensive framework for light field reflection.
• This model supports advanced applications in light-field reconstruction, BRDF identification, and 3D reconstruction.
• The study advances the understanding of light-object interactions in 3D environments.
