Directionally Decomposing Structured Light for Projector Calibration [PDF]

open access: yesIEEE Transactions on Visualization and Computer Graphics, 2021
Intrinsic projector calibration is essential in projection mapping (PM) applications, especially in dynamic PM. However, due to the shallow depth-of-field (DOF) of a projector, more work is needed to ensure accurate calibration. We aim to estimate the intrinsic parameters of a projector while avoiding the limitation of shallow DOF.
