Paper Abstract

Based on digital speckle temporal sequence correlation and speckle projection, an experimental platform was developed to measure the dynamic 3D shape measurement in this paper. Speckle patterns generated by computer were projected onto the quartz clock surface by a white-light projector, and the deformed speckle patterns were acquired by a camera. Programming was written to implement the algorithm to reconstruct every motion of the running clock's pointers. Beyond that, a simple Newton's cradle was established, and the collision course between three steel balls was reconstructed. These experimental results show that the method can be used for dynamic 3D shape measurement, which has an effect on the reconstruction of objects with characteristics of steep variation, isolation and small details.
