Abstract
Abstract An image processing method comprises the steps of generating a road image by photographing a road on which a vehicle is traveling; performing a brightness averaging process of the road image; filtering the road image having undergone the brightness averaging process to detect lane markers; performing an inverse perspective process on the filtered road image; compressing the road image having undergone the inverse perspective process; determining slope in the lane markers from the compressed road image; determining a curvature in the road from the determined slope in the lane markers; and determining a drive direction and a lane deviation of the vehicle.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
107 words
An image processing method comprising the steps of: generating a road image by photographing a road on which a vehicle is traveling; performing a brightness averaging process of the road image; filtering the road image having undergone the brightness averaging process to detect lane markers; performing an inverse perspective process on the filtered road image; compressing the road image having undergone the inverse perspective process in a vertical direction; determining slope in the lane markers from the compressed road image; determining a curvature in the road from the determined slope in the lane markers; and determining a drive direction and a lateral lane deviation of the vehicle.
Claim 2
Dependent Claim
107 words
An image processing method comprising the steps of: generating a road image by photographing a road on which a vehicle is traveling; performing a brightness averaging process of the road image; filtering the road image having undergone the brightness averaging process to detect lane markers; performing an inverse perspective process on the filtered road image; compressing the road image having undergone the inverse perspective process in a vertical direction; determining slope in the lane markers from the compressed road image; determining a curvature in the road from the determined slope in the lane markers; and determining a drive direction and a lateral lane deviation of the vehicle.
Claim 3
Dependent Claim
37 words
The method of claim 1 wherein the brightness averaging process is realized by exchanging a brightness of portions having a value less than an average brightness value of a photographed road image with the average brightness value.
Claim 4
Dependent Claim
37 words
The method of claim 1 further comprising the steps of: determining vehicle speed and driver intentions; and controlling steering of the vehicle based on vehicle speed, driver intentions, and an amount of lane deviation of the vehicle.
