Abstract
3D shape measurements using structured illumination are rarely used for outdoor measurements, although they offer a big potential for accurate and dense shape acquisitions. Usually such setups are used indoor, avoiding the influence of extraneous light sources, e.g. sun. The crucial difficulty is to preserve the image pattern contrast of the illumination while covering larger areas to achieve appropriate measurement volumes. We have developed and will present an outdoor 3D shape measurement setup using stereo-photogrammetry that is capable of acquiring dense and accurate shape representations by narrow spectral filtering. Media that substantiates the suitability of this approach will be shown.
