Abstract
In one embodiment, a method for road geometry matching with componentized junction models is provided. The method includes receiving a plurality of predefined road component models, receiving map data representing a physical road junction, selecting a subset of the plurality of road component models to characterize the physical road junction represented by the received map data, and defining a road junction configuration for the physical road junction with the selected road component models.
Claims20
A method comprising:
- receiving, over a network, a plurality of predefined road component models;
- receiving, over the network, map data representing a physical road junction;
- selecting, using a processor, a subset of the plurality of road component models to characterize the physical road junction represented by the received map data;
- and
- defining, using the processor, a road junction configuration for the physical road junction with the selected road component models.
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 at least perform:
- accessing a plurality of predefined road component models;
- receiving map data comprising line segments representing a physical road junction;
- selecting a subset of the plurality of road component models to characterize the physical road junction represented by the received map data;
- and
- modeling the physical road junction using the selected subset of the plurality of road component models.
A non-transitory computer readable medium including instructions that when executed are operable to:
- receive a plurality of road component models;
- receive map data comprising line segments representing a physical road junction;
- select, using the received map data, a fork component model from the plurality of road component models for characterizing a divergence or a convergence in the physical road junction;
- select, using the received map data, a plurality of straight component models from the plurality of road component models for characterizing one or more sequences of connected straight line segments;
- select, using the received map data, a straight component model or a curved component model from the plurality of road component models for each line segment leading from the divergence or convergence that is not part of the one or more sequences of connected straight line segments;
- and
- select, using the received map data, a straight component model or a curved component model from the plurality of road component models for each line segment that is not leading from the divergence or convergence and that is not part of the one or more sequences of connected straight line segments.
