The BiiM Lab occcupys about 620 SF floor space in Room 122 Nebraska Hall, City Campus. The lab's computational infrastructure includes Linux and Windows servers, and a small HPC cluster with 100+ core processors and GPUs for image procesing, data analysis/visualization, and computation intensive tasks. The cluser includes several high-performance workstations, and is connected to a 18'x6' CineMassive LED wall display. Major BIM software were installed on the lab computers. Major lab equipment also include high-performance infrared imaging camaras, pro-level UAVs with on-board 4K camera, and 3D photogrametry modeling software.
