Abstract: Techniques are described for automated operations to analyze visual data from panorama images captured in multiple rooms of a building and having little-to-no visual overlap in order to generate a floor plan for the building, and subsequently using the generated floor plan in one or more further automated manners, with the floor plan generation further performed in some cases without having or using information from any distance-measuring devices about distances from an image's acquisition location to walls or other objects in the surrounding room. The automated operations may include identifying and aligning pairs of target images acquired at acquisition locations proximate to each other, refining the alignment of inter-image directions and acquisition locations into a global alignment using a common coordinate system, and then using information identified from the images' visual data that includes structural room layouts to generate the floor plan of the building.
