In this paper, we give a state review of modeling methodologies for four-dimensional computer-aided design (4D CAD) and three-dimensional (3D) animation of operations simulation. We then present our efforts of integrating 4D CAD and 3D animation of operations simulation to facilitate the construction planning of the main stadium for the Beijing 2008 Olympic Games (nicknamed the ‘‘Bird’s Nest’’)...

A significant generalization to the language-measuretheoretic path planning algorithm ν is presented that accounts for average dynamic uncertainties in plan execution. The planning problem thus can be solved with parametric input from the dynamics of the robotic platform under consideration. Applicability of the algorithm is demonstrated in a simulated maze solution and by experimental validati...

The lack of indoor floor plans is one the major obstacles to ubiquitous location-based services. Dedicated mobile robots with high-precision sensors can measure and produce accurate maps, but deployment remains low for public. Computer vision techniques are adopted by some existing smartphone-based methods build 3D point cloud, which have cost a quantity efforts image collection risk privacy is...
