3D Video Reconstruction Using Pose Transformation Matrices

The patent applies preliminary action by pre-calculating and storing pose transformation matrices for each camera perspective before the actual 3D reconstruction process. These matrices are computed in advance based on camera positions and orientations, allowing the registration module to quickly align depth video streams without performing complex real-time calculations during reconstruction, thus improving accuracy while managing system complexity

The patent introduces an intermediary registration module that acts as a mediator between the multiple camera input streams and the final 3D reconstruction process. This module uses pose transformation matrices to align and coordinate the depth video streams from different perspectives, simplifying the overall system architecture by centralizing the complex alignment operations in a dedicated intermediate processing stage

The patent applies segmentation by dividing the 3D video processing into distinct modular stages: an acquisition module that collects depth video streams from multiple cameras, a registration module that aligns streams using pose transformation matrices, and a reconstruction module that performs 3D reconstruction. This segmentation allows each module to be optimized independently and enables parallel processing where possible, reducing overall processing time while maintaining immersion quality

The patent uses preliminary action by pre-computing pose transformation matrices and preparing registration data before the actual reconstruction process. This advance preparation reduces the computational burden during real-time reconstruction, allowing faster processing while maintaining high user immersion quality in AR and VR applications
