These values are compared with radial movementsof the dam crest recorded by direct pendulums. The results show differences, only fewmillimeters, being the best result one millimeter discrepancy. The factors that have beenconsidered are the precision and accuracy of the equipment, distance and angle of incidenceof the laser beam, the density of the point cloud and the size of the triangles of the meshes.Considerations about density of point clouds and size of triangular meshes are made. In thisstudy, a 7 cm distance between points and a 20 cm mesh size have given good results. Finally,a methodology is proposed to compare by reference to one of the meshes. 2015 artículo científico 0120-6230 https://www.redalyc.org/articulo.oa?id=43042289012 en http://www.redalyc.org/revista.oa?id=430 Revista Facultad de Ingeniería Universidad de Antioquia application/pdf Universidad de Antioquia Revista Facultad de Ingeniería Universidad de Antioquia (Colombia) Num.76 |
