1. A method comprising, by a computing system:
monitoring one or more regions of a first 3D model of an environment to determine a frequency a respective region changes;
determining a first region of the one or more regions is static based on the frequency the respective region changes;
delaying a first time period to a second time period to update the first 3D model based on comparisons between a second 3D model and first depth measurements of the first region;
detecting whether the first region changed after the second time period based on the comparisons between the second 3D model and the first depth measurements of the first region; and
in response to detecting a change in the first region, updating the first 3D model of the first region.
