Abstract: The data representing the floor plan is processed to classify the different elements in the floor plan. This step may be carried out by processing, using at least one image classification model, different images representing different layers of the floor plan data to identify the type of elements belonging to each layer. A group of elements belonging to a subset of the classifications are then selected and used to segment the floor plan into different spaces. For example, certain boundary elements (e.g. the walls and doors) between different spaces (i.e. rooms) in the floor plan may be identified and selected. Once identified, the boundary elements may be used to segment the floor plan into different spaces, which can then be analysed to determine the characteristics of those spaces, in particular the classification of the space into a type (e.g. an intended use for the space or a type of space, such as an, office, meeting room, kitchen, etc).
