Multi-projector commissioning turns an installed projector array into a calibrated and operational projection system. This multi-projector commissioning guide covers projector identification, physical alignment, focus, lens adjustment, geometry correction, overlap registration, brightness matching, white balance, gamma, color matching, edge blending, baseline documentation and final acceptance testing. A structured commissioning workflow helps project teams verify image continuity, system consistency, signal operation and control functions before immersive, mapping, museum, dome or other professional multi-projector installations are handed over for normal operation.
