Foam-rubber sample volume measuring

For industrial quality control of foam-rubber material, it is required to measure volume of the sample. A new approach is proposed to measure sample volume by images of sample faces. Faces images are got via flatbed scanner. The faces images are processed and the sample is approximated by hexahedron. Then the sample volume is calculated analytically. Also we proposed an iterative approach based on splitting geometrical model of the sample into several smaller hexahedrons. The test results have shown that results of volume measurements obtained by proposed approach coincide well with ones obtained by the standard method. However, repeatability and reproducibility of measurements is better for proposed algorithm, and it is faster.
