  • Patent number: 11480433
    Abstract: Techniques are described for using computing devices to perform automated operations to generate mapping information using inter-connected images of a defined area, and for using the generated mapping information in further automated manners. In at least some situations, the defined area includes an interior of a multi-room building, and the generated information includes a floor map of the building, such as from an automated analysis of multiple panorama images or other images acquired at various viewing locations within the building—in at least some such situations, the generating is further performed without having detailed information about distances from the images' viewing locations to walls or other objects in the surrounding building. The generated floor map and other mapping-related information may be used in various 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.

  • Patent number: 11405558
    Abstract: Techniques are described for using computing devices to perform automated operations to control acquisition of images in a defined area, including obtaining and using data from one or more hardware sensors on a mobile device that is acquiring the images, analyzing the sensor data (e.g., in a real-time manner) to determine the geometric orientation of the mobile device in three-dimensional (3D) space, and using that determined orientation to control the acquisition of further images by the mobile device. In some situations, the determined orientation information may be used in part to automatically generate and display a corresponding GUI (graphical user interface) that is overlaid on and augments displayed images of the environment surrounding the mobile device during the image acquisition process, so as to control the mobile device's geometric orientation in 3D space.

  • Patent number: 11217019
    Abstract: Techniques are described for, given two images taken at two viewing locations, generating and presenting an image transition sequence that simulates viewer movement between the viewing locations, such as without using information about relative distance between the viewing locations and other depth information to objects in an environment around the viewing locations. The start and end images for an image transition sequence may be part of panorama images acquired at the viewing locations, and generating of the image transition sequence may include selecting and using one of multiple types of transition sequences to perform rotating (e.g., from a start image's viewing direction to face toward the viewing location for the end image), zooming (e.g., to simulate moving forward), and/or blending of the end image with a modified version of the start image, with the resulting image transition sequence played as a video or other animation.
