Description
The purpose of this study is development of an image analysis method to obtain particle size information by comparison with conventional sieve analysis and detailed particle size analysis by laser diffraction type particle size analyzer (LISST-100). Introduction of the discriminant analysis method demonstrated to determine the binarization threshold automatically for various color characteristics of sand samples and to obtain appropriate analysis results from various sand samples. It was made clear that the minimum number of detected particles was required around 3000 particles by the proposed method to guarantee the results equivalent to the sieve analysis results. Furthermore, the validity of information of particle size distribution obtained by the proposed method was performed by comparison with the results by LISST analysis. By comparison with the results of particle size distribution by LISST, the results by the proposed method indicated the relevant shape of the particle size distribution. These results showed us usefulness of the proposed method as the simple alternative method of sieve analysis.
