Method, apparatus, and system for dynamic adaptation of an in-vehicle feature detector

An apparatus comprising:

• at least one processor;
• and
• at least one memory including computer program code for one or more programs, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,
• retrieve a map tile from a geographic database, wherein the map tile includes a data layer storing a feature detection model, precomputed weights for the feature detection model, or a combination thereof;
• and wherein the feature detection model, the precomputed weights, or a combination thereof are generated using a training data set collected from a geographic area represented by the map tile;
• and
• adapt an in-vehicle feature detector with the feature detection model, the precomputed weights, or a combination thereof based on determining that the in-vehicle feature detector is in or expected to be in the geographic area,
• wherein the adapted in-vehicle feature detector is used to process sensor data collected from the geographic area to detect one or more features.

A non-transitory computer-readable storage medium carrying one or more sequences of one or more instructions which, when executed by one or more processors, cause an apparatus to perform:

• generating a map layer for one or more map tiles of a tile-based geographic database, the map layer storing a feature detection model, precomputed weights for the feature detection model, or a combination thereof respectively for the one or more map tiles,
• wherein the feature detection model, the precomputed weights, or a combination thereof are generated from a training data set respectively from the one or more map tiles;
• and
• wherein the feature detection model, the precomputed weights, or a combination thereof are dynamically deployed to an in-vehicle feature detector in response to a location-based request for the one or more map tiles.
