Implementation of a Highly Parameterized Digital PIV System On Reconfigurable Hardware

Table 1: Parameters of PIV Circuit Particle image velocimetry (PIV) is used in experimental fluid dynamics to obtain a detailed localized view of velocity vectors in an unsteady fluid flow. In a nutshell, the estimated velocity field is computed from local correlations of snapshot-pairs of the particle-seeded flow, obtained by high-speed cameras [1-2]. PIV is used in a wide range of fields including aerodynamics, automotive design and biomedical engineering. Despite many improvements to PIV methods over the last twenty years, PIV postprocessing remains a computationally intensive task. It becomes a serious bottleneck as snapshot acquisition rates exceed 10,000 frames per second. In this research, we aim to substantially speed up PIV post-processing by implementing it in reconfigurable hardware. Furthermore, this implementation is highly parameterized, supporting adaptation to varying setups and application domains. Laser
