| Abstract: | Thinking over all the advantages and disadvantages of Auto-Grid Method and Photogrammetry, the authors put forward a new method of non-contact measurement named close-range photogrammetry based on digital grids. In this paper, its principle and operation process are introduced and an example used to measure the displacement of an indoor landslide model is given. The experiment result improves that close-range photogrammetry based on digital grids could fleetly and accurately measure the displacement of test model and is a preferable displacement measurement method in landslide model test. |
