获得单纯等倾线的彩色图像颜色分割法

提出彩色图像颜色分割法，即采用彩色图像卡和摄像机，在显示器上显示出彩色等色线与黑色等倾线的耦合条纹图案，应用颜色分割，将等色互消色，保留的等倾线，获得单纯的等倾线，本方法简单易行，可促进光弹性数据采集数据采自动化，获得应力分析的完全解答，进一步提高其应力分析的严谨 。

Color image separation method for obtaining pure isoclinic pattern

It has been a very difficult problem that the pure isolinics are separated from the coupled photoelastic isochromatic isolinic pattern. A new method called the color image separation method was presented here to solve this problem. The coupled color isochromatic isoclinic pattern was shown on screen by means of a color adapter and a color CCD camera. The black isoclinics were preserved and the all color isochromatics were achromatized by the color separation method in order to obtain pure isoclinics. This method was simple and was of great academic and practical value to the automated processing of photoelastic results, and to the complete solution of stress analysis and precision raising.
