Paper Abstract:
|
This paper proposes a method of rock fall simulation using physics engine and 3D models reconstructed by Image-Based Modeling technique. The shape of rocks is important to estimate the accurate way of leap and route of falling motion in 3D simulation. However, in most current researches, although the 3D model of slope is well accurately scanned using a laser scanner, it is not sufficient to estimate the complex behavior of falling rocks due to modeling the shape of rocks is too simple such as sphere or cube. Our proposed method generates 3D models in more accurate shape using Image-Based Modeling technique. The estimated scales are precisely reconstructed as compared with the real measured ones. We evaluate our method in some different places and conduct on rock fall simulation. As the result, by applying physics engine to simulation of falling motion, we confirm that the shape of falling rocks improves the estimation of falling route. |
