Abstract
Artificial neural networks (ANN) may be trained to output estimated floor plans from 3D spaces that would be challenging or impossible for existing techniques to estimate. In embodiments, an ANN may be trained using a supervised approach where top-down views of 3D meshes or point clouds are provided to the ANN as input, with ground truth floor plans provided as output for comparison. A suitably large training set may be used to fully train the ANN on challenging scenarios such as open loop scans and/or unusual geometries. The trained ANN may then be used to accurately estimate floor plans for such 3D spaces. Other embodiments are described.
