A method of measuring 3D velocity field in a large flow field with a single CCD camera is proposed. The method reconstructs the 3D velocity field by using the thickness feature of the light and the particle tracking algorithm. By measuring the flow field in the simulated desulfurization tower , This method can measure steady or low velocity flow field.
