Abstract

A method, apparatus and computer program product are provided for establishing the reliability of crowd sourced data based on the source of the data and the region in which the data is gathered. Methods may include: receiving map data for a network of roads in a geographic area; receiving location accuracy data from different regions within the geographic area, where the location accuracy data for each region may be indicative of an accuracy with which location can be established in the respective region; receiving a plurality of probe data points; determining, for each probe data point, the location accuracy data associated with the location information associated with the respective probe apparatus; determining, for each probe apparatus, a reliability of the one or more sensors; and updating a map database based on at least one probe data point.

First claim

That which is claimed:

1. An apparatus comprising at least one processor and at least one non-transitory memory including computer program code instructions, the computer program code instructions configured to, when executed, cause the apparatus to at least:
receive map data for a network of roads in a geographic area;
receive location accuracy data from different regions within the geographic area, wherein the location accuracy data for each region is indicative of an accuracy with which a location is able to be established in the respective region;
receive a plurality of probe data points, each probe data point received from a probe apparatus of a plurality of probe apparatuses, each probe apparatus comprising one or more sensors and being onboard a respective vehicle, wherein each probe data point comprises location information associated with the respective probe apparatus;
determine, for each probe data point, the location accuracy data associated with the location information associated with the respective probe apparatus;
determine, for each probe apparatus, a reliability of the one or more sensors; and
update a map database based on at least one probe data point from the plurality of probe data points in response to the at least one probe data point satisfying a predetermined value for location accuracy data associated with the location information associated with the respective probe apparatus and the reliability of the one or more sensors of the respective probe apparatus satisfying a reliability value.

2. The apparatus of claim 1 , wherein each probe apparatus comprises a sensor level identification based on the one or more sensors of the respective probe apparatus, wherein causing the apparatus to determine, for each probe apparatus, a reliability of the one or more sensors comprises causing the apparatus to determine the sensor level for each probe apparatus.

3. The apparatus of claim 2 , wherein causing the apparatus to update the map database based, at least in part, on the reliability of the respective probe apparatus satisfying a reliability value comprises causing the apparatus to update the map database based, at least in part, on the sensor level satisfying a sensor level value.

4. The apparatus of claim 1 , wherein the apparatus is further caused to facilitate autonomous vehicle control using the updated map database.

5. The apparatus of claim 1 , wherein the apparatus is further caused to learn a new sensor configuration in response to the one or more sensors of a probe apparatus failing to correspond to a previously identified sensor configuration, wherein causing the apparatus to determine, for each probe apparatus, a reliability of the one or more sensors comprises causing synthetic generation of sensor data from the new sensor configuration to establish a reliability of the new sensor configuration.

6. The apparatus of claim 1 , wherein causing the apparatus to update a map database based on the at least one probe data point comprises causing the apparatus to update the map database based on sensor data associated with the at least one probe data point.

7. The apparatus of claim 6 , wherein the sensor data associated with the at least one probe data point comprises road segment information associated with the location information of the at least one probe data point.

8. A computer program product comprising at least one non-transitory computer-readable storage medium having computer-executable program code portions stored therein, the computer-executable program code portions comprising program code instructions configured to:
receive map data for a network of roads in a geographic area;
receive location accuracy data from different regions within the geographic area, wherein the location accuracy data for each region is indicative of an accuracy with which a location is able to be established in the respective region;
receive a plurality of probe data points, each probe data point received from a probe apparatus of a plurality of probe apparatuses, each probe apparatus comprising one or more sensors and being onboard a respective vehicle, wherein each probe data point comprises location information associated with the respective probe apparatus;
determine, for each probe data point, the location accuracy data associated with the location information associated with the respective probe apparatus;
determine, for each probe apparatus, a reliability of the one or more sensors; and
update a map database based on at least one probe data point from the plurality of probe data points in response to the at least one probe data point satisfying a predetermined value for location accuracy data associated with the location information associated with the respective probe apparatus and the reliability of the one or more sensors of the respective probe apparatus satisfying a reliability value.

9. The computer program product of claim 8 , wherein each probe apparatus comprises a sensor level identification based on the one or more sensors of the respective probe apparatus, wherein the program code instructions to determine, for each probe apparatus, a reliability of the one or more sensors comprise program code instructions to determine the sensor level for each probe apparatus.

10. The computer program product of claim 9 , wherein the program code instructions to update the map database based, at least in part, on the reliability of the respective probe apparatus satisfying a reliability value comprise program code instructions to update the map database based, at least in part, on the sensor level satisfying a sensor level value.

11. The computer program product of claim 8 , further comprising program code instructions to facilitate autonomous vehicle control using the updated map database.

12. The computer program product of claim 8 , further comprising program code instructions to learn a new sensor configuration in response to the one or more sensors of a probe apparatus failing to correspond to a previously identified sensor configuration, wherein the program code instructions to determine, for each probe apparatus, a reliability of the one or more sensors comprise program code instructions for synthetic generation of sensor data from the new sensor configuration to establish a reliability of the new sensor configuration.

13. The computer program product of claim 8 , wherein the program code instructions to update a map database based on the at least one probe data point comprise program code instructions to update the map database based on sensor data associated with the at least one probe data point.

14. The computer program product of claim 13 , wherein the sensor data associated with the at least one probe data point comprises road segment information associated with the location information of the at least one probe data point.

15. A method comprising:
receiving map data for a network of roads in a geographic area;
receiving location accuracy data from different regions within the geographic area, wherein the location accuracy data for each region is indicative of an accuracy with which a location is able to be established in the respective region;
receiving a plurality of probe data points, each probe data point received from a probe apparatus of a plurality of probe apparatuses, each probe apparatus comprising one or more sensors and being onboard a respective vehicle, wherein each probe data point comprises location information associated with the respective probe apparatus;
determining, for each probe data point, the location accuracy data associated with the location information associa
