Photometric calibration plays important role when building seamless appearance of multi-projector display. In this paper, we address photometric issues on chrominance variation and luminance nonuniformity in multi-display system constructed using LCD projectors. A three-phase approach is proposed to construct imaging models, which makes transformations among them when formulating the whole imaging procedure. These models are named as single-projector model, normalized-projector model and display-wall model. Single-projector model describes the imaging procedure from the projector's input color to its measured tristimulus values in CIEXYZ. Normalized-projector model denotes the common gamut of projectors, which normalizes each single-projector model, and makes every projector have the same ranges of chrominance and luminance. The display-wall model treats the whole display as one projector, which has similar photometric model to single LCD projector. Weighting light contributions from all projectors using the display wall model, our method can achieve visually plausible seamlessness.
