Abstract
Provided are methods for methods and systems for measuring sensor visibility, which can include obtaining sensor data associated with an autonomous vehicle and determining a blockage parameter indicative of a blockage of a sensor based on a comparison of the sensor data with secondary data. Some methods described also include controlling an operation of an autonomous vehicle based on the blockage parameter. Systems and computer program products are also provided.
Claims18
A method, comprising:
- obtaining, using at least one processor, first sensor data from a first sensor associated with a first autonomous vehicle, wherein the first sensor data is indicative of an environment in which the first autonomous vehicle is operating;
- obtaining, using the at least one processor, environment data indicative of the environment;
- determining, using the at least one processor, based on a comparison of the first sensor data and the environment data, a first blockage parameter indicative of a first blockage of the first sensor;
- obtaining, using the at least one processor, a second blockage parameter from a second autonomous vehicle operating in the environment, wherein the second blockage parameter indicates a second blockage of a second sensor associated with the second autonomous vehicle, wherein the second autonomous vehicle determines the second blockage parameter;
- determining, using the at least one processor, an adverse weather condition in the environment based on the first blockage parameter and the second blockage parameter;
- controlling, based on the determined adverse weather condition, an operation of the first autonomous vehicle;
- and
- communicating the determined adverse weather condition to a fleet management system, wherein the fleet management system is configured to updates driving parameters for a fleet of autonomous vehicles in the environment based on the determined adverse weather condition.

A non-transitory computer readable medium comprising instructions stored thereon that, when executed by at least one processor, cause the at least one processor to carry out operations comprising:
- obtaining first sensor data from a first sensor associated with a first autonomous vehicle, wherein the first sensor data is indicative of an environment in which the first autonomous vehicle is operating;
- obtaining environment data indicative of the environment;
- determining based on a comparison of the first sensor data and the environment data, a first blockage parameter indicative of a first blockage of the first sensor;
- obtaining, using the at least one processor, a second blockage parameter from a second autonomous vehicle operating in the environment, wherein the second blockage parameter indicates a second blockage of a second sensor associated with the second autonomous vehicle, wherein the second autonomous vehicle determines the second blockage parameter;
- determining an adverse weather condition in the environment based on the first blockage parameter and the second blockage parameter;
- controlling, based on the determined adverse weather condition, an operation of the first autonomous vehicle;
- and
- communicating the determined adverse weather condition to a fleet management system, wherein the fleet management system is configured to update driving parameters for a fleet of autonomous vehicles in the environment based on the determined adverse weather condition.

- obtain environment data indicative of the environment;
- determine, based on a comparison of the first sensor data and the environment data, a first blockage parameter indicative of a first blockage of the first sensor;
- obtain a second blockage parameter from a second autonomous vehicle operating in the environment, wherein the second blockage parameter indicates a second blockage of a second sensor associated with the second autonomous vehicle, wherein the second autonomous vehicle determines the second blockage parameter;
- determine an adverse weather condition in the environment based on the first blockage parameter and the second blockage parameter;
- control, based on the determined adverse weather condition, an operation of the first autonomous vehicle;
- and
- communicate the determined adverse weather condition to a fleet management system, wherein the fleet management system is configured to update driving parameters for a fleet of autonomous vehicles in the environment based on the determined adverse weather condition.
