Patent Applications by Waymo LLC
Inventor(s): David I. Ferguson of San Francisco CA (US) for waymo llc, Nathaniel Fairfield of Rockingham VA (US) for waymo llc, Anthony Levandowski of Palo Alto CA (US) for waymo llc
IPC Code(s): B60W30/18, G06V20/56, G06V20/58
CPC Code(s): B60W30/18154
Abstract: methods and devices for detecting traffic signals and their associated states are disclosed. in one embodiment, an example method includes a scanning a target area using one or more sensors of a vehicle to obtain target area information. the vehicle may be configured to operate in an autonomous mode, and the target area may be a type of area where traffic signals are typically located. the method may also include detecting a traffic signal in the target area information, determining a location of the traffic signal, and determining a state of the traffic signal. also, a confidence in the traffic signal may be determined. for example, the location of the traffic signal may be compared to known locations of traffic signals. based on the state of the traffic signal and the confidence in the traffic signal, the vehicle may be controlled in the autonomous mode.

IPC Code(s): G05D1/00, B60R11/00, B60R11/04, B60W10/04, B60W10/20, B60W30/18, H04Q9/00
CPC Code(s): G05D1/0248
Abstract: the technology relates to developing a highly accurate understanding of a vehicle's sensor fields of view in relation to the vehicle itself. a training phase is employed to gather sensor data in various situations and scenarios, and a modeling phase takes such information and identifies self-returns and other signals that should either be excluded from analysis during real-time driving or accounted for to avoid false positives. the result is a sensor field of view model for a particular vehicle, which can be extended to other similar makes and models of that vehicle. this approach enables a vehicle to determine when sensor data is of the vehicle or something else. as a result, the detailed modeling allowing the on-board computing system to make driving decisions and take other actions based on accurate sensor information.

IPC Code(s): G06V20/58, B60W60/00, G06F18/2431
CPC Code(s): G06V20/582
Abstract: the described aspects and implementations enable efficient identification of real and image signs in autonomous vehicle (av) applications. in one implementation, disclosed is a method and a system to perform the method that includes obtaining, using a sensing system of the av, a combined image that includes a camera image and a depth information for a region of an environment of the av, classifying a first sign in the combined image as an image-true sign, performing a spatial validation of the first sign, which includes evaluation of a spatial relationship of the first sign and one or more objects in the region of the environment of the av, and identifying, based on the performed spatial validation, the first sign as a real sign.
