Abstract
- In this paper, we present a novel technique for optical 3-D surface reconstruction by using line-scan cameras and structured light in combination. The approach generating structured light is customized to the special demands of line-scan image capturing. Owing to the distributed generation of light and the absence of shading elements, we obtain a light intensity that is comparable with conventional line lights. Thus, we achieve short integration times which is a necessary condition in most line-scan applications. Furthermore, with our approach we can generate different pattern sequences, which allows us to implement coded light methods such as time correlation or phase shifting. The light patterns can be switched synchronously with the captured lines of the camera. Thus, we are able to measure continuously whereby a single surface scan is sufficient to calculate a high-quality 3-D reconstruction. [ABSTRACT FROM PUBLISHER]
