Abstract
A system includes a processor and a memory in communication with the processor having one or more modules. The modules include instructions that cause the processor to receive first sensor information from a first sensor and second sensor information of a shared field of view. The instructions cause the processor to detect one or more objects within the shared field of view using the first sensor information and the second sensor information. When one or more discrepancies are identified between the one or more objects detected using the first sensor information and the one or more objects detected using the second sensor information are detected, the instructions that cause the processor to determine that the first sensor or the second sensor needs cleaning.
Claims20
A system comprising:
- a processor;
- a memory in communication with the processor, the memory including a receiver module, an object detection module, and a pollution detection module;
- wherein the receiver module includes instructions that, when executed by the processor, cause the processor to:
- receive first sensor information from a first sensor mounted to a vehicle having a first field of view, and
- receive second sensor information from a second sensor mounted to the vehicle having a second field of view, wherein at least a portion of the second field of view overlaps at least a portion of the first field of view to define a shared field of view;
- wherein the object detection module includes instructions that, when executed by the processor, cause the processor to:
- detect one or more objects within the shared field of view using the first sensor information, and
- detect one or more objects within the shared field of view using the second sensor information;
- and
- wherein the pollution detection module includes instructions that, when executed by the processor, cause the processor to:
- determine one or more discrepancies between the one or more objects detected using the first sensor information and the one or more objects detected using the second sensor information, and
- determine when one of the first sensor and the second sensor needs cleaning based on the one or more discrepancies.
A method comprising the steps of:
- receiving first sensor information from a first sensor mounted to a vehicle having a first field of view;
- receiving second sensor information from a second sensor mounted to the vehicle having a second field of view, wherein at least a portion of the second field of view overlaps at least a portion of the first field of view to define a shared field of view;
- detecting one or more objects within the shared field of view using the first sensor information;
- detecting one or more objects within the shared field of view using the second sensor information;
- determining one or more discrepancies between the one or more objects detected using the first sensor information and the one or more objects detected using the second sensor information;
- and
- determining when one of the first sensor and the second sensor needs cleaning based on the one or more discrepancies.
A non-transitory computer-readable medium storing instructions that, when executed by a processor, causes the processor to:
- receive first sensor information from a first sensor mounted to a vehicle having a first field of view;
- receive second sensor information from a second sensor mounted to the vehicle having a second field of view, wherein at least a portion of the second field of view overlaps at least a portion of the first field of view to define a shared field of view;
- detect one or more objects within the shared field of view using the first sensor information;
- detect one or more objects within the shared field of view using the second sensor information;
- determine one or more discrepancies between the one or more objects detected using the first sensor information and the one or more objects detected using the second sensor information;
- and
- determine when one of the first sensor and the second sensor needs cleaning based on the one or more discrepancies.
