Map Feature Extraction Using Overhead View Images

A system comprising:

• at least one processor and at least one memory storing instructions that, when executed by the at least one processor, cause the system to perform:
• receiving a plurality of images of a geographical area that are captured by one or more vehicles from a plurality of trajectories;
• determining whether the plurality of images captured from the plurality of trajectories satisfy a predetermined threshold associated with generating one or more overhead view images that include one or more semantic map features that are capable of being extracted therefrom;
• subsequent to determining that the plurality of images satisfy the predetermined threshold, generating the one or more overhead view images of the geographical area;
• identifying the one or more semantic map features of the geographical area included in the one or more overhead view images;
• extracting the one or more semantic map features of the geographical area from the one or more overhead view images;
• and
• translating the extracted semantic map features to a semantic map layer of a geometric map associated with the geographical area.

A non-transitory computer-readable medium comprising computer-executable instructions which, when executed by at least one processor of a system, cause the system to perform:

• receiving a plurality of images of a geographical area captured by one or more vehicles from a plurality of trajectories;
• determining whether the plurality of images captured from the plurality of trajectories satisfy a predetermined threshold associated with generating one or more overhead view images that include one or more semantic map features that are capable of being extracted therefrom;
• subsequent to determining that the plurality of images satisfy the predetermined threshold, generating the one or more overhead view images of the geographical area;
• identifying the one or more semantic map features of the geographical area included in the one or more overhead view images;
• extracting the one or more semantic map features of the geographical area from the one or more overhead view images;
• and
• translating the extracted semantic map features to a semantic map layer of a geometric map associated with the geographical area.
