Measurement of elasticity modulus using image processing

In this paper, we propose a scheme to measure the Elasticity Modulus of textile using image processing techniques, here the elasticity modulus is measured indirectly by measuring stiffness of the material. The material whose stiffness is to be measured is subjected to a known force, and the deformation caused in the material due to applied load is measured using image processing. The deformation caused depends on stiffness of the textile used, by making use of relation between stiffness and deformation we can calculate the stiffness. Using this stiffness, elasticity modulus is derived. Web camera is used for the purpose of capturing the image, which is then acquired on the LabVIEW platform for processing. The data is processed by image processing techniques to compute stiffness and elasticity. The system was subjected to test and results showed it had achieved desired objectives.
