摘要： Aspects of the invention relate generally to autonomous vehicles. The features described improve the safety, use, driver experience, and performance of these vehicles by performing a behavior analysis on mobile objects in the vicinity of an autonomous vehicle. Specifically, the autonomous vehicle is capable of detecting nearby objects, such as vehicles and pedestrians, and is able to determine how the detected vehicles and pedestrians perceive their surroundings. The autonomous vehicle may then use this information to safely maneuver around all nearby objects.

摘要： 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.

摘要： 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.

摘要： Methods and systems for estimating vehicle speed are disclosed. A light detecting and ranging (LIDAR) device obtains a set of spatial points indicative of locations of reflective surfaces in an environment of the LIDAR device. A plurality of target points that correspond to a target surface of a target vehicle is identified in the set of spatial points. The plurality of target points includes a first point indicative of a first location on the target surface obtained by the LIDAR device at a first time and a second point indicative of a second location on the target surface obtained by the LIDAR device at a second time. A speed of the target vehicle is estimated based on the first location, the first time, the second location, and the second time.
