| Abstract: | This paper proposed a laser collimating automatic method for monitoring the deformation of dams.A series of Frensnel Plates were connected with the dam.The principle and application of the Frensnel Plates were discribed.A CCD camera was used to capture the images of Frensnel Plates and the computer calculated the central point of the images automaticalliy and precisely.We developed a set of measuring system which showed the reliability and precision of the method. |
