Three dimensional geometry characterization using structured light

摘要

In this paper I review sev eral studies related with the development of the doctoral thesis of Paulo J. Tavares. The thesis was directed at implementing different three - dimensional surface acquisition methods with structured light fields and essentially describes these implement ations, and the difficulties experienced thereof. Several innovative works have been done in the areas of 3D imaging with active image processing, Fourier transform phase analysis, coherent light fringe projection, phase - to - height calibration in phase meas urement profilometry, feature detection in planar calibration targets for camera calibration and; fringe distortion correction resourcing to the Optical Transfer Function. This paper presents the main results obtained in those studies which were all perfor med at LOME – the Optics and Experimental Mechanics Laboratory of the Mechanical Engineering department of Porto University.
