Patent number: 10444759Abstract: Systems, methods, and apparatuses described herein are directed to performing segmentation on voxels representing three-dimensional data to identify static and dynamic objects. LIDAR data may be captured by a perception system for an autonomous vehicle and represented in a voxel space. Operations may include determining a drivable surface by parsing individual voxels to determine an orientation of a surface normal of a planar approximation of the voxelized data relative to a reference direction. Clustering techniques can be used to grow a ground plane including a plurality of locally flat voxels. Ground plane data can be set aside from the voxel space, and the remaining voxels can be clustered to determine objects. Voxel data can be analyzed over time to determine dynamic objects. Segmentation information associated with ground voxels, static object, and dynamic objects can be provided to a tracker and/or planner in conjunction with operating the autonomous vehicle.Type: GrantFiled: June 14, 2017Date of Patent: October 15, 2019Assignee: Zoox, Inc.Inventors: Bertrand Robert Douillard, Subhasis Das, Zeng Wang, Dragomir Dimitrov Anguelov, Jesse Sol Levinson

Publication number: 20190295315Abstract: Techniques for generating maps without shadows are discussed herein. A plurality of images can be captured by a vehicle traversing an environment representing various perspectives and/or lighting conditions in the environment. A shadow within an image can be identified by a machine learning algorithm trained to detect shadows in images and/or by projecting the image onto a three-dimensional (3D) map of the environment and identifying candidate shadow regions based on the geometry of the 3D map and the location of the light source. Shadows can be removed or minimized by utilizing blending or duplicating techniques. Color information and reflectance information can be added to the 3D map to generate a textured 3D map. A textured 3D map without shadows can be used to simulate the environment under different lighting conditions.Type: ApplicationFiled: March 21, 2018Publication date: September 26, 2019Inventors: Jesse Sol Levinson, Ashutosh Gajanan Rege, Brice Rebsamen, Elena Stumm, Nitesh Shroff, Derek Adams

Publication number: 20190278292Abstract: Techniques for decimating portions of a map of an environment are discussed herein. The environment can be represented by a three-dimensional (3D) map including a plurality of polygons and semantic information associated with the polygons. In some cases, decimation operations may be based on semantic information associated with the environment. Differing decimation operations and/or levels may be applied to polygons of different semantic classifications or differing contribution levels. Boundaries between regions having different semantic information can be preserved. Meshes can be decimated using different decimation operators or decimation levels and an accuracy of localizing can be compared using the various decimated meshes. An optimal mesh can be selected and sent to vehicles for localizing the vehicles in the environment.Type: ApplicationFiled: March 6, 2018Publication date: September 12, 2019Inventors: Jesse Sol Levinson, Ashutosh Gajanan Rege, Brice Rebsamen, Elena Stumm, Nitesh Shroff, Derek Adams

Patent number: 10401852Abstract: Various embodiments relate generally to autonomous vehicles and associated mechanical, electrical and electronic hardware, computer software and systems, and wired and wireless network communications to provide an autonomous vehicle fleet as a service. More specifically, systems, devices, and methods are configured to initiate modification of trajectories to influence navigation of autonomous vehicles. In particular, a method may include receiving a teleoperation message via a communication link from an autonomous vehicle, detecting data from the teleoperation message specifying an event associated with the autonomous vehicle, identifying one or more courses of action to perform responsive to detecting the data specifying the event, and generating visualization data to present information associated with the event to a display of a teleoperator computing device.Type: GrantFiled: October 21, 2016Date of Patent: September 3, 2019Assignee: Zoox, Inc.Inventors: Jesse Sol Levinson, Ashutosh Gajanan Rege, Rachad Youssef Gamara, Gabriel Thurston Sibley, Timothy David Kentley-Klay, Gary Linscott

Publication number: 20190258737Abstract: A system may receive a sensor dataset representing an environment and use the dataset to create or update a map. In creating or updating the map, the system may determine an object classification of one or more detected objects and only selectively incorporate data into the map based at least in part on the classification. The map may be associated with the classification (or semantic) information of the objects, as well as weights based on the classification. Similarly, datasets with selected classes of data removed may be used for system localization. Further, the system may determine an object track of the objects. When updating the map, voxels in a voxel space may indicate an occupied voxel based on a threshold number of observances. The object track and clean map can then be used for controlling an autonomous vehicle.Type: ApplicationFiled: February 20, 2018Publication date: August 22, 2019Inventors: Zeng Wang, Nitesh Shroff, Dragomir Dimitrov Anguelov, Subhasis Das, Jesse Sol Levinson, Brice Rebsamen

Publication number: 20190049566Abstract: Perception sensors of a vehicle can be used for various operating functions of the vehicle. A computing device may receive sensor data from the perception sensors, and may calibrate the perception sensors using the sensor data, to enable effective operation of the vehicle. To calibrate the sensors, the computing device may project the sensor data into a voxel space, and determine a voxel score comprising an occupancy score and a residual value for each voxel. The computing device may then adjust an estimated position and/or orientation of the sensors, and associated sensor data, from at least one perception sensor to minimize the voxel score. The computing device may calibrate the sensor using the adjustments corresponding to the minimized voxel score. Additionally, the computing device may be configured to calculate an error in a position associated with the vehicle by calibrating data corresponding to a same point captured at different times.Type: ApplicationFiled: August 11, 2017Publication date: February 14, 2019Inventors: Derek Adams, Ian Baldwin, Bertrand Robert Douillard, Jesse Sol Levinson

Publication number: 20180329411Abstract: A system, an apparatus or a process may be configured to implement an application that applies artificial intelligence and/or machine-learning techniques to predict an optimal course of action (or a subset of courses of action) for an autonomous vehicle system (e.g., one or more of a planner of an autonomous vehicle, a simulator, or a teleoperator) to undertake based on suboptimal autonomous vehicle performance and/or changes in detected sensor data (e.g., new buildings, landmarks, potholes, etc.).
