Abstract
Systems and methods are provided for analyzing vehicle signal lights in order to operate an autonomous vehicle. A method includes receiving an image from a camera regarding a vehicle proximate to the autonomous vehicle. Data from a lidar sensor regarding the proximate vehicle is used to determine object information for identifying a subsection within the camera image. The identified subsection corresponds to an area of the proximate vehicle containing one or more vehicle signals. One or more vehicle signal lights of the proximate vehicle is located by using the identified camera image subsection as an area of focus.
Claims20
A method for analyzing vehicle signal lights in order to operate an autonomous vehicle, comprising:
- receiving, by one or more processors, an image from a camera regarding a vehicle proximate to the autonomous vehicle;
- using, by the one or more processors, data from a lidar sensor regarding the proximate vehicle to determine object geometry and position information for identifying a subsection within the camera image, wherein the identified subsection corresponds to an area of the proximate vehicle containing one or more vehicle signals;
- and
- locating, by the one or more processors, one or more vehicle signal lights of the proximate vehicle by using the identified camera image subsection as an area of focus;
- wherein tracking of the proximate vehicle is based upon the located one or more vehicle signal lights of the proximate vehicle.
A system for analyzing vehicle signal lights in order to operate an autonomous vehicle, the system comprising:
- a storage device for storing instructions for performing safety analysis of autonomous vehicle operation;
- and
- one or more data processors configured to execute the instructions to:
- receive an image from a camera regarding a vehicle proximate to the autonomous vehicle;
- use data from a lidar sensor regarding the proximate vehicle to determine object geometry and position information for identifying a subsection within the camera image, wherein the identified subsection corresponds to an area of the proximate vehicle containing one or more vehicle signals;
- and
- locate one or more vehicle signal lights of the proximate vehicle by using the identified camera image subsection as an area of focus;
- wherein tracking of the proximate vehicle is based upon the located one or more vehicle signal lights of the proximate vehicle.
An autonomous vehicle comprising:
- at least a camera and lidar sensor that provides sensor data;
- and
- a controller that, by a processor and based on the sensor data:
- receives an image from the camera regarding a vehicle proximate to the autonomous vehicle;
- uses data from the lidar sensor regarding the proximate vehicle to determine object geometry and position information for identifying a subsection within the camera image, wherein the identified subsection corresponds to an area of the proximate vehicle containing one or more vehicle signals;
- and
- locates one or more vehicle signal lights of the proximate vehicle by using the identified camera image subsection as an area of focus;
- wherein tracking of the proximate vehicle is based upon the located one or more vehicle signal lights of the proximate vehicle.
