Abstract: Techniques are described for using computing devices to perform automated operations to generate mapping information via analysis of visual data of photos of a defined area, and for using the generated mapping information in further automated manners, including to display the generated mapping information via various types of visualizations corresponding graphical user interfaces. In some situations, the defined area includes an interior of a multi-room building, and the generated information includes at least a partial floor plan and/or other modeled representation of the building—in addition, the generating may be further performed without having measured depth information about distances from the photos' acquisition locations to walls or other objects in the surrounding building. The generated floor plan and/or other mapping-related information may be further used in various manners, including for controlling navigation of devices (e.g., autonomous vehicles), etc.

Abstract: Techniques are described for computing devices to perform automated operations related to using images acquired in a building as part of an automated generation process of a floor plan or other mapping information for the building, in some cases without using depth information from depth-sensing equipment about distances from the images' acquisition locations to objects in the surrounding building, and for subsequent use in further automated manners, such as controlling navigation of mobile devices and/or for display to end users in a corresponding graphical user interface. The analysis and assessment of the building images may, for example, include performing an automated assessment of one or more characteristics of the mapping information generation process (e.g., a predicted amount of time for completion) and to provide automated instructions (e.g., to adjust image acquisition device settings) or other feedback to improve the generation process (e.g., reduce that predicted time).

Abstract: Techniques are described for automated operations to analyze visual data from images acquired in multiple rooms of a building to generate one or more types of building information (e.g., global inter-image pose data, a floor plan for the building, etc.), such as by simultaneously or otherwise concurrently analyzing groups of three or more images having at least pairwise visual overlap between pairs of those images to determine information that includes global inter-image pose and structural element locations, and for subsequently using the generated building information in one or more further automated manners, with the building information 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.

Abstract: Techniques are described for using multiple data capture devices at a building to automatically generate a building floor plan and to determine associated absolute location data for the generated floor plan. In some situations, a building floor plan is automatically generated by analyzing visual data of images captured at multiple image acquisition locations by a camera device to determine room shapes of surrounding rooms, and GPS absolute location data is associated with the generated floor plan using additional data captured at other data capture locations at the building by a separate mobile device that moves independently from the camera device, such as by automatically determining relative positions of the camera device and the mobile device to extend the absolute location data from the mobile device to the camera device's image acquisition location and its surrounding room shape.

Abstract: Techniques are described for using computing devices to perform automated operations for determining the acquisition location of an image using an analysis of the image's visual contents. In at least some situations, images to be analyzed include panorama images acquired at acquisition locations in an interior of a multi-room building, and the determined acquisition location information includes a location on a floor plan of the building and in some cases orientation direction information—in at least some such situations, the acquisition location determination is performed without having or using information from any distance-measuring devices about distances from an image's acquisition location to objects in the surrounding building. The acquisition location information may be used in various automated manners, including for controlling navigation of devices (e.g., autonomous vehicles), for display on one or more client devices in corresponding graphical user interfaces, etc.

Abstract: Techniques are described for computing devices to perform automated operations related to using images acquired in a building as part of an automated generation process of a floor plan or other mapping information for the building, in some cases without using depth information from depth-sensing equipment about distances from the images' acquisition locations to objects in the surrounding building, and for subsequent use in further automated manners, such as controlling navigation of mobile devices and/or for display to end users in a corresponding graphical user interface. The automated analysis and assessment of the building images may, for example, include incrementally generating partial versions of the mapping information, determining acquisition instructions related to further acquisition of additional images and/or other types of data (e.g., to reduce uncertainty associated with portions of the partial mapping information or otherwise obtain missing data), and providing corresponding guidance in or more manners.

Abstract: Techniques are described for using data capture devices at a building to automatically generate a building floor plan and associate absolute location data with it, such as by associating separately captured GPS data or other absolute location data with the floor plan, and for presenting a model of the generated floor plan using the associated absolute location data (e.g., at a map position corresponding to the associated absolute location data). In some situations, the presenting of such a building floor plan includes showing varying levels of detail about structural aspects of the building interior and other interior aspects, such as based on the map zoom level and/or other factors. In addition, such presenting of a building floor plan may include automatically determining and using data about surroundings of the building, such as to provide information about views from the building, about directions to nearby points of interest, etc.
