THE STUDY OF IMAGE PROCESSING OF RUBBER
LARGE DEFORMATION BASED ON MATLAB
ABSTRACT
Use troupes face as a CCD image sensor non-contact measurement of rubber in the process
of stretching deformation, not only better than the extension of the conventional measurement
of the objective approach, but also can measure the tensile deformation of material to fracture
the whole process. In addition, the advantages of this method have no wear and tear, and do not
introduce additional error of measurement. High-precision measurements show the deformation
rate and automatically generate the report, in particular the ability to automatically map -
deformation curves, which can be measured under the test rubber sample in a variety of
parameters limit. Based on the CCD (Charge Coupled Device) technology and image
recognition applications theory of large deformation and rubber non-contact test methods study
to be large deformation Rubber mechanical properties of testing theory and technical methods
related to the development of virtual machines, and put into practical application, In which
digital image processing techniques based on MATLAB to achieve this article is the key to
virtual machines. Strain through electrical measurement principles and sensor technology, can
pull in digital; through the intake across the CCD array of rubber deformation in real-time
graphics data processing, access to the rubber elongation. This test system is a software
platform National Instruments (National Instruments) to develop the virtual instrument
graphical programming language LabVIEW. The author of this paper, application of
non-contact measurement method for the mechanical properties of rubber, the results achieved
the desired objectives and requirements. In this paper, the application of CCD technology and
image processing technology used in non-contact measurement of new ideas to solve the
traditional method of measurement which is difficult to achieve.
