SYSTEM FOR SIMULTANEOUS PROJECTIONS OF MULTIPLE PHASE-SHIFTED PATTERNS FOR THE THREE-DIMENSIONAL INSPECTION OF AN OBJECT |
摘要 |
A three-dimensional image grabber allowing for the simultaneous projection of multiple phase-shifted patterns onto an object, and the simultaneous acquisition of multiple images of these phase-shifted patterns is described herein. The grabber comprises a pattern projecting assembly and an image acquisition assembly. The pattern projecting assembly includes, for example, a spectral splitter or a plurality of light sources, grids and projectors for simultaneous projection of a plurality of patterns under different monochromatic lights. The image acquisition assembly includes, for example, a CCD camera sensitive to the different monochromatic lights, or a plurality of CCD cameras with filters to gather lights incoming for the object simultaneously illuminated by the plurality of phase-shifted patterns. A method and a system for measuring the relief of an object, using the above-mentioned process, is also disclosed. |
