Abstract: Aspects of the present disclosure relate generally to safe and effective use of autonomous vehicles. More specifically, an autonomous vehicle is able to detect objects in its surroundings which are within the sensor fields. In response to detecting objects, the computer may adjust the autonomous vehicle's speed or change direction. In some examples, however, the sensor fields may be changed or become less reliable based on objects or other features in the vehicle's surroundings. As a result, the vehicle's computer may calculate the size and shape of the area of sensor diminution and a new sensor field based on this area of diminution. In response to identifying the area of sensor diminution or the new sensor field, the vehicle's computer may change the control strategies of the vehicle.

Abstract: The present invention relates to using image content to facilitate navigation in panoramic image data. In an embodiment, a computer-implemented method for navigating in panoramic image data includes: (1) determining an intersection of a ray and a virtual model, wherein the ray extends from a camera viewport of an image and the virtual model comprises a plurality of facade planes; (2) retrieving a panoramic image; (3) orienting the panoramic image to the intersection; and (4) displaying the oriented panoramic image.

Abstract: Aspects of the invention pertain to enhanced zooming capability of user devices. A user device such as a mobile phone with a camera may capture images of different objects of interest. The capture and zooming limitations of the user device are overcome by replacing, supplementing or otherwise enhancing the image taken with one or more geo-coded images stored in a database. For instance, if the user attempts to zoom in on a feature of an object of interest and exceeds the zooming capability of the user device, a request is sent to a remote server to provide an image showing the feature of the object of interest at a desired resolution. The server determines which, if any, stored images correlate to the captured image of the object of interest. The resulting imagery is provided to the user device and is presented on a display.

Abstract: A system and method of displaying transitions between street level images is provided. In one aspect, the system and method creates a plurality of polygons that are both textured with images from a 2D street level image and associated with 3D positions, where the 3D positions correspond with the 3D positions of the objects contained in the image. These polygons, in turn, are rendered from different perspectives to convey the appearance of moving among the objects contained in the original image.

Abstract: Aspects of the disclosure relate generally to notifying a pedestrian of the intent of a self-driving vehicle. For example, the vehicle may include sensors which detect an object such as a pedestrian attempting or about to cross the roadway in front of the vehicle. The vehicle's computer may then determine the correct way to respond to the pedestrian. For example, the computer may determine that the vehicle should stop or slow down, yield, or stop if it is safe to do so. The vehicle may then provide a notification to the pedestrian of what the vehicle is going to or is currently doing. For example, the vehicle may include a physical signaling device, an electronic sign or lights, a speaker for providing audible notifications, etc.
