myimagelib.pivLib.read_piv

myimagelib.pivLib.read_piv(pivDir)

Read piv data from pivDir as X, Y, U, V. pivDir contains *.csv files, which store PIV data of each image pair in a separated file. The data are organized in 4-column tables, (x, y, u, v). This function reconstructs the 2D data, by inferring the dimensions from data.

Parameters:

pivDir – directory of the folder hosting PIV data.

Returns:

x, y, u, v – 2D PIV data.

Return type:

4-tuple of 2D numpy.array

>>> from myimagelib.pivLib import read_piv
>>> x, y, u, v = read_piv(pivDir)
