Abstract
The Scheimpflug principle is commonly used in single-camera-based and multi-camera-based MFPP systems to extend the mutual overlap range of different views in the object space. We set up a dual-camera-based MFPP system and performed 3D measurements of plates, standard balls, and some specifically designed samples using the phase map stereo matching method. We conclude that the dual-camera-based system wins in measurement accuracy, while the single-camera-based system has better integrity, which may provide a reference for the system design in implementing industrial applications.
