Abstract
The application of fast 3D measuring methods is a fundamental venture in industrial measuring technology. This paper introduces the digital fringe projection technology based on the Digital Light Projection technology (DLP) from Texas Instruments as a measuring method for inline 3D measurement and inspection for industrial use. In this paper in the first part will be described the fundamental principles of the used 3D measuring method and the calibration of the measuring devices. In the second part will be described and/or represented the special needs of the hard and software components enabling the application of the digital fringe projection technology as a 3D inline measuring method for manufacturing systems. In a third part of the paper is described an inline system for 3D measurement and/or inspection of electronic components.
