3D Facial Feature Reconstruction Based on Dual-View Analysis

The recon system performs 3D facial feature reconstruction based on dual-view analysis, utilizing one frontal projection view and another horizontally rotated view. This methodology assumes an orthographic projection model where camera positions and orientations are predetermined. In implementation, the algorithm first processes the frontal projection view to reconstruct facial planar contours and establish the fundamental facial geometry through coordinate mapping. Subsequently, the horizontally rotated view provides supplementary depth information and finer facial details using stereoscopic disparity calculations. The getfeature function plays a crucial role in this pipeline by automatically detecting and annotating key facial landmarks - including eye corners, nose tip, and mouth contours - through feature extraction algorithms. This dual-view approach enables more comprehensive and accurate 3D reconstruction while preserving critical spatial relationships throughout the reconstruction workflow.
