Geometry and resolution in triangulation vision systems

The paper presents an overview of available camera and laser work geometries in vision systems used for 3D image acquisition. Parameters defining the vision system resolution are discussed, and analysis and limitations resulting from the adopted system geometry are presented. An imaging resolution analysis was presented for each of the presented geometries. Occlusion phenomenon and its impact on 3D image recording were also discussed. The summary of the work includes a comparison of resolutions for different geometries of the 3D vision system and a comparison of the impact of occlusion on the quality of the recorded image.
