Visible Light Positioning With Lam\'e Curve LEDs: A Generic Approach for Camera Pose Estimation
Researchers have developed a new method for camera pose estimation using visible light positioning (VLP) with Lamé curve-shaped LEDs. This approach, termed LC-VLP, aims to reduce the number of LEDs required by treating various LED shapes as unified Lamé curves. The system involves LEDs broadcasting their parameters, which a camera-equipped receiver captures to estimate its pose through a nonlinear least-squares problem. A novel correspondence-free PnP algorithm provides reliable initialization, and experiments show LC-VLP outperforms existing methods, achieving position errors reduced by over 30% and an average position accuracy of less than 4 cm.
