摘要

Two different photogrammetric techniques for the determination of high-resolved simultaneous 3-D velocity fields in flows are outlined and compared: a technique based on the discrete visualization of a flow with tracer particles and recording of image sequences by multiple CCD cameras, and a technique based on scanning an observation volume of a flow marked with dye by a laser lightsheet and tracking of flow patterns by 3-D least-squares matching in sequences of voxel da-tasets. The article shows the principles of both methods, hardware configurations for data acquisition, application fields, and results achieved.
