Patent Applications by Waymo LLC
20250110218. LIDAR PULSE ELONGATION_simplified_abstract_(waymo llc)
Inventor(s): Luke Wachter of San Francisco CA US for waymo llc, Pierre-Yves Droz of Los Altos CA US for waymo llc, Clayton Kunz of Mill Valley CA US for waymo llc
IPC Code(s): G01S7/4861, G01S7/497, G01S17/04, G01S17/931
CPC Code(s): G01S7/4861
Abstract: systems and methods are disclosed to identify a presence of a volumetric medium in an environment associated with a lidar system. in some implementations, the lidar system may emit a light pulse into the environment, receive a return light pulse corresponding to reflection of the emitted light pulse by a surface in the environment, and determine a pulse width of the received light pulse. the lidar system may compare the determined pulse width with a reference pulse width, and determine an amount of pulse elongation of the received light pulse. the lidar system may classify the surface as either an object to be avoided by a vehicle or as air particulates associated with the volumetric medium based, at least in part, on the determined amount of pulse elongation.

IPC Code(s): G01S13/58, G01S7/41, G01S13/89, G01S13/931
CPC Code(s): G01S13/581
Abstract: example embodiments relate techniques and systems for generating multi-axis radar velocity images using stereo radar. a vehicle radar system receives radar first radar data from a first radar and second radar data from a second radar, which are coupled at different locations on a vehicle traveling in an environment. the system determines a first radial speed and a second radial speed for an object based on the first and second radar data, respectively, and then estimates a velocity vector for the object relative to the vehicle based on the first and second radial speeds. the system can provide the estimated velocity vector as an input into a neural network and enable vehicle systems to control the vehicle based on the output from the neural network.

IPC Code(s): G06V20/58, B60Q5/00, G06V20/56
CPC Code(s): G06V20/58
Abstract: example embodiments relate to pedestrian countdown signal classification to increase pedestrian behavior legibility. an example embodiment includes a method that includes obtaining, by a computing system of a vehicle, a camera image patch. the method further includes determining, by the computing system, using the camera image patch and a pedestrian countdown signal classifier model, a state of a pedestrian countdown signal. the method also includes determining, by the computing system based on the state of the pedestrian countdown signal, a prediction of whether a pedestrian will enter a crosswalk governed by the pedestrian countdown signal. and the method includes, based on the prediction, causing, by the computing system, the vehicle to perform an invitation action that invites a pedestrian to enter the crosswalk.
