Appl. No.:

17/893376

Inventors:

- Mountain View CA, US
Changchang Wu - Bothell WA, US
Alper Ayvaci - San Jose CA, US
Tiffany Chen - Santa Clara CA, US
Lo Po Tsui - Mountain View CA, US

Sean Rafferty - Sunnyvale CA, US

International Classification:

G06K 19/067
G09F 3/00

Abstract:

Aspects of the disclosure provide for automatically generating labels for sensor data. For instance, first sensor data, for a vehicle may be identified. This first sensor data may have been captured by a first sensor of the vehicle at a first location during a first point in time and may be associated with a first label for an object. Second sensor data for the vehicle may be identified. The second sensor data may have been captured by a second sensor of the vehicle at a second location at a second point in time outside of the first point in time. The second location is different from the first location. A determination may be made as to whether the object is a static object. Based on the determination that the object is a static object, the first label may be used to automatically generate a second label for the second sensor data.

Appl. No.:

15/843366

Inventors:

- Mountain View CA, US
Robert Anderson - Seattle WA, US
Changchang Wu - Mountain View CA, US
Michael Krainin - Mountain View CA, US

International Classification:

G02B 27/01
G06T 15/20

Abstract:

Systems and methods are described include defining, at a computing device, a set of images based on captured images, projecting, at the computing device, a portion of the set of images from a planar perspective image plane onto a spherical image plane by recasting a plurality of viewing rays associated with the portion of the set of images from a plurality of viewpoints arranged around a curved path to a viewpoint, determining, at the computing device, a periphery boundary corresponding to the viewpoint and generating updated images by removing pixels that are outside of the periphery boundary, and providing, for display, the updated images within the bounds of the periphery boundary.
