Use of environmental information to aid image processing for autonomous vehicles
DCFirst Claim
1. A method comprising:
- receiving, using a processor, image data indicative of an environment from at least one sensor of a vehicle, wherein the vehicle is configured to operate in an autonomous mode in the environment, and wherein the vehicle is substantially in a lane of travel of the environment;
comparing the image data to a predetermined image map of a road in the environment indicative of the lane of travel, wherein the comparing comprises projecting the predetermined image map onto the image data;
based on the comparing and further based on predetermined features of the lane of travel indicated by the predetermined image map, determining, in the image data, a portion of the image data that includes features of the lane of travel that correspond to at least a portion of the predetermined features of the lane of travel;
determining whether an object is present in the lane of travel based on the determined portion of the image data and by disregarding a remaining portion of the image data, wherein the remaining portion of the image data comprises image data other than the portion of the image data; and
based on the determination of whether the object is present in the lane of travel, providing instructions to control the vehicle in the autonomous mode in the environment.

Abstract
An autonomous vehicle may be configured to use environmental information for image processing. The vehicle may be configured to operate in an autonomous mode in an environment and may be operating substantially in a lane of travel of the environment. The vehicle may include a sensor configured to receive image data indicative of the environment. The vehicle may also include a computer system configured to compare environmental information indicative of the lane of travel to the image data so as to determine a portion of the image data that corresponds to the lane of travel of the environment. Based on the portion of the image data that corresponds to the lane of travel of the environment and by disregarding a remaining portion of the image data, the vehicle may determine whether an object is present in the lane, and based on the determination, provide instructions to control the vehicle in the autonomous mode in the environment.

7. A vehicle comprising:
-
a sensor configured to receive image data indicative of an environment, wherein the vehicle is configured to operate in an autonomous mode in the environment, and wherein the vehicle is substantially in a lane of travel of the environment; a computer system, wherein the computer system is configured to; compare the image data to a predetermined image map of a road in the environment indicative of the lane of travel, wherein the comparing comprises projecting the predetermined image map onto the image data; based on the comparing and further based on predetermined features of the lane of travel indicated by the predetermined image map, determine, in the image data, a portion of the image data that includes features of the lane of travel that correspond to at least a portion of the predetermined features of the lane of travel; determine whether an object is present in the lane of travel based on the determined portion of the image data and by disregarding a remaining portion of the image data, wherein the remaining portion of the image data comprises image data other than the portion of the image data; and based on the determination of whether the object is present in the lane of travel, provide instructions to control the vehicle in the autonomous mode in the environment. - View Dependent Claims (8, 9, 10, 11)

12. A non-transitory computer readable medium having stored therein instructions that when executed by a computer system in a vehicle, cause the computer system to perform functions comprising:
-
receiving image data indicative of an environment from at least one sensor of the vehicle, wherein the vehicle is configured to operate in an autonomous mode in the environment, and wherein the vehicle is substantially in a lane of travel of the environment; comparing the image data to a predetermined image map of a road in the environment indicative of the lane of travel, wherein the comparing comprises projecting the predetermined image map onto the image data; based on the comparing and further based on predetermined features of the lane of travel indicated by the predetermined image map, determining, in the image data, a portion of the image data that includes features of the lane of travel that correspond to at least a portion of the predetermined features of the lane of travel; determining whether an object is present in the lane of travel based on the determined portion of the image data and by disregarding a remaining portion of the image data, wherein the remaining portion of the image data comprises image data other than the portion of the image data; and based on the determination of whether the object is present in the lane of travel, providing instructions to control the vehicle in the autonomous mode in the environment. - View Dependent Claims (13, 14, 15, 16, 17)
