Autoexposure for three-dimensional shape measurement using a digital-light-processing projector

摘要: Automatically adapting the camera exposure time is crucial for industrial applications where minimum human intervention usually desirable. However, it very challenging to realize such a capability conventional fringe projection system only finite increment of allowed due its digital generation nature. We study sinusoidal patterns by properly defocusing binary ones, which permits use an arbitrary time. This provides potential adapt automatically. present principle automatic technique and show some experimental results.
