In order to characterize the mechanical behavior of a reinforced concrete beam–column joint, an experiment is designed whereby different histories of increasing cyclic loads are applied, and the structure deformation (as well as the morphology of apparent surface cracks) is studied using multi-view correlation. The complex three-dimensional geometry and the slender nature of the beam and column call for numerous digital cameras were positioned around the specimen. Assessing the feasibility of image acquisition and estimating a priori uncertainties on multi-view correlation became a true challenge. It is shown that the recourse to photo-realistic rendering software provides the needed tools to perform this experiment design optimization.

面向多视图系统监控的结构测试的虚拟设计和优化

为了表征钢筋混凝土梁柱节点的力学行为，设计了一个实验，其中施加了不同的循环荷载增加历史，并使用多重分析研究了结构变形（以及表观裂缝的形态）。查看相关性。复杂的 3D 几何形状和细长的梁柱要求在样品周围放置大量数码相机。评估图像采集的可行性和估计多视图相关性的先验不确定性成为一个真正的挑战。结果表明，对照片级逼真渲染软件的求助提供了执行此实验设计优化所需的工具。
