Abstract
A method of measuring panel stiffness of an automobile part outer panel by pushing an indenter onto a surface of the panel in a pushing direction intersecting the surface under a load to deform the panel and measuring deformation of the panel includes arranging grids in a lattice form to a surface of a site of the panel; arranging markers previously knowing three-dimensional position information on a periphery of the site; pushing the indenter onto the surface of the site under the load and moving the indenter in a direction perpendicular to the pushing direction, during which the grids on the surface deformed by loading of the indenter are simultaneously and repeatedly shot from plural positions by plural cameras; and calculating position information of the grids corresponding to the markers based on the image data to measure change in deformation of the panel associated with movement of the indenter.
