摘要

A 3-D measuring method for particle movement was established by using a single-lens dual-camera system. The light through an object-space telecentric lens was split half-and-half by a beam splitter and then are received by two CCD industrial cameras, respectively. These two image sensors have different distances from the telecentric lens. As for the same imaging particle, two images with different degrees of defocus will be captured. These two images were used to solve the ambiguous problem of 3-D particle positions. Combining with the PTV technology and the single-frame and multiple-exposure imaging method, the system can determine the magnitude and direction of 3-D velocity. The feasibility was then proved by experiments.
