Abstract
An apparatus of providing guidance information provides guidance information about the result of recognizing a crosswalk around a vehicle as information for inducing safe driving. The guidance information about a crosswalk is differently provided in accordance with a surrounding situation concerned with forward traveling of the vehicle.
Claims18
A method of providing guidance information, the method being implemented by a computer, the method comprising:
- confirming a result of recognizing a crosswalk around a vehicle;
- comparing the crosswalk recognition result with map data on a global positioning system (GPS) reception position of the vehicle;
- amending a map matching position of the GPS reception position based on the comparison result;
- and
- providing a position information of the vehicle as guidance information based on the amended map matching position,
- wherein comparing of the crosswalk recognition result with the map data comprises confirming whether a real crosswalk exists within a threshold range, based on the map data on the GPS reception position, and
- wherein amending the map matching position comprises amending the map matching position when the crosswalk recognition result does not correspond to whether the real crosswalk exists.

A method of providing guidance information, the method being implemented by a computer, the method comprising:
- confirming a result of recognizing a crosswalk around a vehicle;
- confirming a result of recognizing a surrounding situation concerned with forward traveling of the vehicle;
- distinguishing guidance information for the crosswalk recognition result based on the surrounding situation recognition result to provide the guidance information;
- and
- recognizing a crosswalk in an image by analyzing the image obtained by photographing a surrounding of the vehicle,
- wherein recognizing of the crosswalk in the image is performed by detecting a pattern corresponding to the crosswalk in a binary image which is generated by applying a mini-max filter to a horizontal line of the image to binarize the image.
