Patent attributes
Certain examples described herein relate to modelling a three-dimensional space. Image data from at least one capture device is used to generate a three-dimensional model of the three-dimensional space. In certain examples, the three-dimensional model is segmented into active and inactive portions based on at least one model property. The examples are configured to use the active portions to update the three-dimensional model over time. Registration is also performed to align active portions of the three-dimensional model with inactive portions of the three-dimensional model over time. The registration aligns active portions of the three-dimensional model generated following an observation of a region of the three-dimensional space with inactive portions of the model generated following at least one previous observation of said region.
