Apparatus and method for lane marking analysis

摘要

Embodiments of the present invention provide a method of determining a location at which a lane divider marking changes type, comprising determining (350) a first type of lane divider (120) marking based upon a frequency spectrum determined by Fourier analysis of first image data (431) corresponding to a first area, determining (350) a second type of lane divider (130) marking based upon a frequency spectrum determined by Fourier analysis of second image data (432) corresponding to a second area, and determining (360) a geographic location at which the lane divider marking changes type according to a comparison of the first and second types (120, 130) of lane divider marking.

1. A method of determining a location at which a lane divider marking changes type, comprising:
determining a lane divider marking type separating a first lane from a second lane for a first road segment based upon a frequency spectrum determined by Fourier analysis of first image data corresponding to a first area; determining a lane divider marking type separating the first lane from the second lane for a second road segment based upon a frequency spectrum determined by Fourier analysis of second image data corresponding to a second area; and determining a geographic location at which the lane divider marking separating the first lane from the second lane changes type according to a comparison of the lane divider marking types for the first and second road segments.
