LaVision's DaVis software with the implemented uncertainty quantification tool, enables end users to calculate an uncertainty value for each processed vector in their PIV data (i.e. an uncertainty field).

Computing Stereo-PIV including PIV uncertainty on the GPU from a pair of camera images will be accelerated by a factor of about 10 depending on the camera type and spatial resolution.. The comparison is based on representative PIV processing settings using a state-of-the-art single GPU versus an Intel Xeon CPU multi-core high-performance PC.
