研究目的
To propose a calibration method for deploying a large-scale projection-based floor display system that corrects both perspective and lens distortions without requiring a calibration board or significant overlapping among projections and cameras' fields of view.
研究成果
The proposed calibration method effectively corrects projective and lens distortions in a large-scale projection system without moving the devices or the projection plane. The quantitative experiment shows close estimation results to ground truth values, and the projection experiment demonstrates a more seamless projection result compared to only projective distortion correction.
研究不足
The method's optimization is based on projecting and capturing iterations, which is time-consuming, although this is mitigated by generating a projection camera pixel map in advance to perform projecting and capturing virtually.
