摘要: 本文论述了光弹性应力等倾线和等差线数字图象处理的原理和方法,解决了等差线稀少和等倾线模糊不清问题。给出了典型试件的应力分析,并与理论解进行了比较,精度令人满意。

Abstract: This paper proposes digital image processing methods of multiplying and sharping isochromatic and isoclinic fringes. Two difficult technical problems in engineering application(indistinct isoclinic fringe and rare isochromatic fringe)have been well solved. Typical stress analysis examples are illustrated. The accuracy is satisfactory.
