Paper Abstract

An increasingly common technique for extracting three-dimensional (3-D) information for robotics and automation involves a camera and laser spot projector. This paper presents an analysis of the accuracy of the 3-D measurement using this approach. The sources of error are assumed to arise from limited precision of the camera and imperfect system calibration. The resultant error function relates the system accuracy to both internal camera and external system geometry. For a typical system configuration, utilizing solid state cameras, data show that internal camera parameters have negligible effect on the system accuracy. The greatest determinant of system performance is the system alignment. This is followed closely by the camera orientation angle.
