Hrabovska N. Information technologies of three-dimensional reconstruction from images of surfaceses defects are for the lambertian reflection model of the light

Dissertation is sanctified to development and improvement of methods, algorithms and information technologies of a three-dimensional reconstruction that is based on the lambertian reflection model of light. The improvement of reconstruction it takes place by the increase of automation and reduction to influence of errors and artefacts on the process of reconstruction. Properties of lambertian reflection model of light are analysed under act of direction of illumination and diffuse coefficient, that gave an opportunity to get a method and algorithm of three-dimensional reconstruction on the basis of triad of images that guarantees absence of influence of еру barrage pels and changeability of diffuse coefficient on the process of three-dimensional reconstruction, and to define his errors. For the increase of automation in composition the method it is suggested to apply the method of the optical monitoring of direction of illumination from information of image of test standard that has the known normal vectors Information technologies of three-dimensional reconstruction are analysed at reduction of video information to two and one image.
