System and method of representing and tracking time-based information in two-dimensional building documentation

摘要

A system that includes computer executable instructions that, when executed by the processor, cause the processor to perform operations including receiving a first 2D map of a location. The first 2D map was generated at a first time based on first scan data from a coordinate measurement scanner and a portable computing device. The coordinate measurement scanner includes a light source, a first image sensor, and a controller. The portable computing device includes a second image sensor. A second 2D map of the location is received. The second 2D map was generated at a second time based on second scan data from the coordinate measurement scanner and the portable computing device. The first 2D map is aligned with the second 2D map, and their contents are compared. Any differences in the contents of the first 2D map and the second 2D map are output.
