Actively modifying a field of view of an autonomous vehicle in view of constraints
Methods and devices for actively modifying a field of view of an autonomous vehicle in view of constraints are disclosed. In one embodiment, an example method is disclosed that includes causing a sensor in an autonomous vehicle to sense information about an environment in a first field of view, where a portion of the environment is obscured in the first field of view. The example method further includes determining a desired field of view in which the portion of the environment is not obscured and, based on the desired field of view and a set of constraints for the vehicle, determining a second field of view in which the portion of the environment is less obscured than in the first field of view. The example method further includes modifying a position of the vehicle, thereby causing the sensor to sense information in the second field of view.
1. A system for a vehicle, comprising:
a sensor configured to sense information about an environment of the vehicle in a field of view of the sensor;
an additional sensor; and
a processor in the vehicle configured to (i) analyze the sensed information from the sensor to detect a plurality of obstacles in the environment of the vehicle, (ii) determine that the field of view of the sensor is obscured by at least one detected obstacle, thereby inhibiting the sensor to sense information about a portion of the environment of the vehicle, and (iii) responsive to determining by the processor that the field of view of the sensor is obscured, obtain, by the processor, information from the additional sensor, wherein the additional sensor is able to sense information about the portion of the environment.
2. The system of claim 1 , wherein the sensor is a camera, and wherein the processor is configured to analyze images captured by the camera to detect obstacles.
3. The system of claim 1 , wherein the processor is further configured to determine a requested field of view and to send to the additional sensor a request to sense information in the requested field of view.
4. The system of claim 3 , wherein the requested field of view is less obscured by the at least one detected obstacle than the field of view of the sensor.
5. The system of claim 1 , wherein the processor is further configured to modify the field of view of the sensor.
6. The system of claim 1 , wherein the vehicle is an autonomous vehicle.
7. A method, comprising:
analyzing, by a processor in a vehicle, information sensed by a sensor to detect a plurality of obstacles in an environment of the vehicle, wherein the sensor is configured to sense information about the environment of the vehicle in a field of view of the sensor;
determining, by the processor, that the field of view of the sensor is obscured by at least one detected obstacle, thereby inhibiting the sensor to sense information about a portion of the environment of the vehicle; and
responsive to determining by the processor that the field of view of the sensor is obscured, obtaining, by the processor, information from an additional sensor, wherein the additional sensor is able to sense information about the portion of the environment.
8. The method of claim 7 , wherein the sensor is a camera, and wherein analyzing information by the sensor comprises analyzing images captured by the camera.
9. The method of claim 7 , further comprising:
determining, by the processor, a requested field of view; and
sending to the additional sensor a request to sense information in the requested field of view.
10. The method of claim 9 , wherein the requested field of view is less obscured by the at least one detected obstacle than the field of view of the sensor.
11. The method of claim 7 , further comprising:
modifying the field of view of the sensor.
12. The method of claim 7 , wherein the vehicle is an autonomous vehicle.
13. A non-transitory computer-readable medium having stored therein instructions executable by a computing device to cause the computing device to perform operations, wherein the operations comprise:
analyzing, by a processor in a vehicle, information sensed by a sensor to detect a plurality of obstacles in an environment of the vehicle, wherein the sensor is configured to sense information about the environment of the vehicle in a field of view of the sensor;
determining, by the processor, that the field of view of the sensor is obscured by at least one detected obstacle, thereby inhibiting the sensor to sense information about a portion of the environment of the vehicle; and
responsive to determining by the processor that the field of view of the sensor is obscured, obtaining, by the processor, information from an additional sensor, wherein the additional sensor is able to sense information about the portion of the environment.
14. The non-transitory computer-readable medium of claim 13 , wherein the sensor is a camera, and wherein analyzing information by the sensor comprises analyzing images captured by the camera.
15. The non-transitory computer-readable medium of claim 13 , wherein the operations further comprise:
determining a requested field of view; and
sending to the additional sensor a request to sense information in the requested field of view.
16. The non-transitory computer-readable medium of claim 15 , wherein the requested field of view is less obscured by the at least one detected obstacle than the field of view of the sensor.
17. The non-transitory computer-readable medium of claim 13 , wherein the operations further comprise:
modifying the field of view of the sensor.
