Particles` grain shape describing method, involves recording image of particle and/or grain flow by digital camera, and determining resolution coefficients for evaluation of point-move curve using Fourier analysis

摘要

The method involves recording an image of a particle and/or grain flow by a digital camera, and storing as digitalized image data. A digitalized projection surface is produced from the data for the particle to be described by a data processing unit. The surface is separated into a surface pixel and an edge pixel by surface erosion. Resolution coefficients are determined for an evaluation of point-move curve using Fourier analysis.
