Our Objective is to develop the Digital Engineering SW for Manufacturing Industry (for example Automobile, Electronics et all) with advanced image processing technologies owned by Riken. We especially focus on X-ray CT measurement and modeling Objects with Voxel, and integrate these Voxel data with Polygon and CAD-data, and develop the simulation, inspection functionalities with supporting product design and manufacturing.
