MoiréBoard: A Stable, Accurate and Low-cost Camera Tracking Method
summary
A camera tracking method that recovers 3-DOF position from moiré patterns produced by two overlaid grids claims commercial-VR accuracy while using cheap materials (LED or printed grid + 3D‑printed mesh) and runs at high frame rate. It computes position from measured grid spacing, moiré period and peak displacement, requires no camera calibration, needs no powered markers, and a prototype integrated into a phone VR headset reproduces headset motion closely compared to laser‑station systems.
