Abstract
A road furniture item or another type of road object is detected by at least one sensor. An associated geographic position associated with the road furniture item or road object is determined. After a predetermined time is reached, the geographic position is compared to a local database. A remote database is updated after the predetermined time is reached and according to the comparison with the local database. In some examples, the data indicative of the road furniture item or the road object is deleted based on a confidence level in the local database.
Claims20
A method for updating a geographic database at specified times, the method comprising:
- accessing an update interval for the geographic database from a memory;
- sending at least one scheduled update to one or more fleet vehicles at the update interval;
- sending data indicative of the update interval to the one or more fleet vehicles;
- and
- receiving an update message from the one or more fleet vehicles, the update message including data for a road object collected at a time corresponding to at least a predetermined portion of the update interval before the update message is generated.
An apparatus for updating a geographic database comprising:
- a server geographic database including data indicative of roads and road features;
- a memory configured to store at least one update interval;
- and
- a controller configured to send at least one scheduled update to one or more local geographic databases at the at least one update interval and analyze an update message from the one or more local geographic databases, the update message including data for a road feature collected in time at least a predetermined portion of the update interval before the update message is generated.
A non-transitory computer readable medium including instructions that when executed by a processor are configured to perform:
- receiving, from a memory, sensor data indicative of a road object;
- identifying a confidence value in a local database;
- comparing the confidence value to a confidence threshold;
- and
- discarding the sensor data indicative of the road object from the memory in response to the confidence value exceeding the confidence threshold.
