| 摘要 |
<p>The present invention relates to a measuring system suitable for strain analysis of three-dimensional patterned components (10). The system features a camera (8) with five degrees of freedom, mounted on a coordinate measurement machine (CMM) (1) which has a built-in computer (7), linked to an image processing system. The computer is responsible for all measuring and calculation processes, i.e.: preliminary measurement of the global shape of the component (3) using sensor technology; positioning and orienting of the camera; communication with the image processing system to determine the number of images; transmitting this number of images to the image processing system, so as to calculate the parameters of the pattern; actual calculation of the parameters; application of several calculation algorithms to these parameters in order to convert the image output to a connective mesh of three-dimensional world coordinates of the points of intersection; calculation of the field of displacement and strains as well as graphical and/or numerical presentation of the results.</p> |
