Abstract:
1. A process for measuring three-dimensional objects in a three-dimensional environment, comprising the steps of: taking at least one image of said environment by at least one camera; detecting discontinuities of appearance in the image; relating said discontinuities with geometric contours, said contours having positions and shapes in the image which are defined by parameters including numerals; matching said geometric contours with said discontinuities by adjusting said parameters; numerically relating said geometric contours with geometric objects in the three-dimensional environment, three-dimensional positions and volume shapes of said geometric objects in the three-dimensional environment being defined by three-dimensional parameters including numerals; estimating said three-dimensional positions and volume shapes of said geometric objects in the three-dimensional environment in computing geometric projections of said geometric objects onto said at least one image according to a match between said projection and said geometric contours; and, creating a representation of the three-dimensional environment, said representation comprising said geometric objects, according to the parameters defining the positions and shapes of said geometric objects.
