Multiprojector Multicamera Structured Light Surface Scanner

Structured light surface scanners are usually limited to a single projector and cannot provide full profile in scan. Multiple projectors must be employed extend the imaging area over whole of imaged object. Using multiple is challenging problem due inter-projector interference which make pattern decoding hard. We describe practical approach multi-projector structured scanning based on sinusoidal fringe patterns temporal phase shifting allows simultaneous employment. In our different set shifts assigned each enable efficient robust separation observed combined into contributions projector. The proposed does not place any restrictions placement nor upper limit number used. demonstrate applicability scanner comprised three six cameras.
