In an aspect, a computer implemented method receives, for a volume within a building, a set of images captured from corresponding locations within the volume, each image taken at a corresponding location, and each image having data specifying the corresponding location from which the image was captured; receiving a three-dimensional point cloud of the volume; detects, using one or more computer vision processing techniques, items of interest within the images; for each item of interest in each image, determines, based on the point cloud and the data specifying the corresponding locations from which the images were captured, a coordinate for the item of interest, the coordinate specifying a location within the volume that corresponds to the item of interest in the image; and stores the data specifying each item of interest and, for each item of interest, its determined coordinate, in a data storage.
