Artificial intelligence-based actual measurement method and device

The invention discloses an artificial intelligence-based actual measurement method and device. The artificial intelligence-based actual measurement method includes the following steps that: the 3D initial model of a target space is acquired through a laser radar; the parameters of at least one target sub-model in the 3D initial model are obtained; a building information model is generated according to the parameters; the building information model and the preset model of the target space are fitted; and the comparative data of the building information model and the preset model are acquired according to a fitting result. With the artificial intelligence-based actual measurement method and device of the invention adopted, semantic segmentation can be performed on an indoor scene, so that an object can be automatically recognized from the scanning scene of a tangible building; the core algorithm of 3D actual measurement can be solved based on artificial intelligence; planes obtained through semantic analysis on
