Unsupervised online learning of overhanging structure detector for map generation
First Claim
1. A method comprising:
- receiving an image captured by an image capturing device in communication with a probe apparatus on board a vehicle, wherein the image comprises at least a portion of a roadway;
generating a sky projection based on at least a portion of the image;
determining whether the sky projection comprises a feature that defines a feature direction that is substantially non-vertical; and
responsive to determining that the sky projection does comprise a feature that defines a feature direction that is substantially non-vertical, determining that the image comprises an overhanging structure.

Abstract
Methods, apparatuses, computer program products, and systems are provided for training a network to act as an overhanging structure detector using an unsupervised machine learning technique. An image is received that was captured by an image capturing device in communication with a probe apparatus on board a vehicle, wherein the image comprises at least a portion of a roadway. A sky projection is generated based on at least a portion of the image. It is determined whether the sky projection comprises a feature that defines a feature direction that is substantially non-vertical. Responsive to determining that the sky projection does comprise a feature that defines a feature direction that is substantially non-vertical, it is determined that the image comprises an overhanging structure.
