Optical Measurement Of Mechanical Image Stress Analysis Software

In this dissertation, we use C++ language on the platform Visual C++6.0 to set up a set of optical measure image strain analysis software system framework. In this framework we successfully realized planar photo elastic image strain analysis function. This system provides photo elastic, moire, holographic, speckle technology contained in optical measure strain and displacement analysis software interface, and mainly realizes photo elastic image collection, interference image pretreatment, automatic skeleton extract method, automatic main strain trace protraction method and planar photo elastic image strain analysis function. All the work that the author has done has established a good foundation for more realization of an intact optical measure image strain analysis software system. Furthermore, engineer and lab assistant can quickly obtain concise, intuitionistic and quantificational information. The emphasis of this dissertation contains:(1)Set up a set of software management and development environment independent hardware.(2)In interference fringe image processing, propose a new method of skeleton extracting.(3)In main stress trace protraction, based on the character of main stress trace, propose an automatic method.(4)Under the new environment, realize planar photo elastic stress analysis. Based on this, it is easy to realize spatial photo elastic stress analysis.(5)Under the new environment, realize interference fringe image preprocessing.
