Abstract

Claims (29)

1. A method comprising:

identifying one or more features for one or more operational actions that are to be performed at an edge node of an edge computing system, the one or more features including information usable by the edge node to execute the one or more operational actions;

retrieving a first set of the one or more features during an input processing stage, and the retrieving comprises:

accessing a timestamp associated with the one or more features that exist in a local map at a time of the input processing stage, the timestamp identifying when the one or more features were included in the local map;

based on the timestamp, determining an amount of time that has passed since the one or more features were included in the local map; and

using the one or more features that exist in the local map at the time of the input processing stage in the execution of the one or more operational actions when it is determined that the amount of time that has passed does not exceed a maximum allowed amount of time;

using the first set of the one or more features in the execution of the one or more operational actions;

in response to the execution of the one or more operational actions, obtaining a second set of the one or more features; and

in response to retrieving the first set of the one or more features or in response to obtaining the second set of the one or more features, updating the local map to include the one or more features, the local map including a subset of a global map, where the local map and the global map represent a shared representation of a map structure.

2. The method of claim 1 , wherein retrieving the first set of the one or more features during the input processing stage comprises:

retrieving one or more features that exist in the local map at a time of the input processing stage.

3. The method of claim 1 , wherein retrieving the first set of the one or more features during the input processing stage comprises:

extracting the one or more features from sensor data collected at the edge node.

4. The method of claim 1 , wherein retrieving the first set of the one or more features during the input processing stage comprises:

receiving the one or more features from a central node of the edge computing system in response to a request for the one or more features from the edge node.

5. The method of claim 1 , wherein the one or more features are associated with a timestamp when being included in the local map during the update to the local map.

6. The method of claim 1 , further comprising:

in response to determining that the amount of time that has passed does exceed a maximum allowed amount of time, not using the one or more features that exist in the local map at the time of the input processing stage in the execution of the one or more operational actions;

extracting the one or more features from sensor data collected at the edge node; or

receiving the one or more features from a central node of the edge computing system in response to a request for the one or more features from the edge node.

7. The method of claim 1 , further comprising:

in response to obtaining the second set of the one or more features, updating in the local map the one or more features of the second set that existed in the local map prior to the execution of the one or more operational actions.

8. The method of claim 1 , further comprising:

in response to obtaining the second set of the one or more features, updating in the local map the one or more features of the second set that are included in a request from a central node of the edge computing system.

9. The method of claim 1 , further comprising:

in response to obtaining the second set of the one or more features, not updating in the local map the one or more features of the second set that did not exist in the local map prior to the execution of the one or more operational actions and that are not included in a request from a central node of the edge computing system.

10. The method of claim 1 , wherein the one or more operational actions to be executed are defined in a decision-making task generated by a central node of the edge computing system.

11. The method of claim 1 , wherein the global map has a hierarchical structure.

12. The method of claim 11 , wherein the global map is an Octomap.
