Los Alamitos: IEEE Computer Soc, p. 46-53, 1998.http://hdl.handle.net/11449/38731Geometric accuracy of a close-range photogrammetric system is assessed in this paper considering surface reconstruction with structured light as its main purpose. The system is based on an off-the-shelf digital camera and a pattern projector. The mathematical model for reconstruction is based on the parametric equation of the projected straight line combined with collinearity equations. A sequential approach for system calibration was developed and is presented. Results obtained from real data are also presented and discussed. Experiments with real data using a prototype have indicated 0.5mm of accuracy in height determination and 0.2mm in the XY plane considering an application where the object was 1630mm distant from the camera.46-53engreconstructioncalibrationclose-range photogrammetryTrabalho apresentado em evento10.1109/SIBGRA.1998.722732WOS:000076805000008Acesso aberto
