Abstract

The requirement for a non-transparent Lambertian like surface in optical 3D measurements with fringe pattern projection cannot be satisfied at translucent objects. The translucency causes artifacts and systematic errors in the pattern decoding, which could lead to measurement errors and a decrease of measurement stability. In this work, the influence of light wavelength on 3D measurements was investigated at a stereoscopic system consisting of two filter wheel cameras with narrowband bandpass filters and a projector with a wide-band light source. The experimental results show a significant wavelength dependency of the systematic measurement deviation and the measurement stability.
