In this study, we develop the spatial filtering velocimetry (SFV) technique to measure the velocity distribution of small spherical and irregular particle flows using a linear CCD camera. In addition, energy barycentre correction algorithm is used to enhance the measurement accuracy. A constantly running conveyor belt is used to test the accuracy of this SFV system. Furthermore, the velocity distributions of the spherical and irregular particle flows in a rotating drum are measured to demonstrate the usability of this method in a granular system. We further discuss the effect of the key system parameters on the results of the measurement, and the optimal thresholds of the parameters are given in this paper.
