Abstract

Line scan cameras offer very high spatial resolution, allowing even multispectral color acquisition and are therefore often used for quality control at the conveyor belt. A logical extension is to complement the broad spectrum of the missing channel depth data. For industrial use, the technology combines the advantages of customized cameras with proven 3D evaluation methods which are known from 3D-matrix camera systems. The present system allows the rapid and simultaneous detection of color and 3D depth with small random errors, preferably relatively flat (not fissured) surfaces. Standard deviation of 10 microns could already be realized in practice. Color and 3D data are from the same measurement system and are in exactly the same coordinate system. This can be a significant advantage in quality assurance, such as testing manufactured goods to a good match of form and texture. The use of massively parallel hardware (GPUs) currently allow performance of approximately 100 million disparity values per second.
