Systems, Methods, and Graphical User Interfaces for Annotating, Measuring, and Modeling Environments

A system displays a representation of a camera field of view including a first portion of a physical environment, captures depth information indicative of a first subset of the first portion, and displays, overlaid on a portion of the representation of the field of view corresponding to the first subset, an indication of an extent of the first portion for which depth information has been captured. In response to detecting movement of the field of view, the system: updates the representation of the field of view to include a representation of a second portion of the physical environment; captures depth information indicative of a second subset of the second portion; and updates the indication to indicate an extent of the second portion for which depth information has been captured, including displaying the indication overlaid on a portion of the representation of the field of view corresponding to the second subset.
