Laser-based structured light technique for 3D reconstruction using Extreme Laser stripes extraction method with global information extraction

Abstract

A laser based structured-light technique is proposed for use in three-dimensional reconstruction. This technique is produced from an extensive experimental evaluation for the fundamental laser stripe extraction methods used with the structured-laser-light technique. Based on this evaluation, the proposed technique uses the extreme with centroid for calculating the probable laser stripe’s locations. It then extracts the global visual information from the scanned scene and uses this information to filter out all the unreliable locations. This makes the new technique has superior extraction capability for the structures-laser-light and robust to the scanning conditions that disturb the reconstruction process. The performance of the proposed technique was evaluated through a series of experiments. The evaluation results show high 3D reconstruction performance for the proposed technique in comparison to the traditional technique when extracting laser-stripes. They also show how the global visual information is efficient for locating these stripes from the other illumination sources.
