Image processor for automotive vehicle
First Claim
1. An image processor for an automotive vehicle comprising:
- an imaging element for capturing an image of a road, on which the automotive vehicle is located;
a traffic lane line detection element for detecting a position of a traffic lane line on the road by determining an edge of the traffic lane line on the basis of the image of the road;
a distance distribution calculation element for calculating a distance distribution of an edge intensity of the traffic lane line, the distance distribution corresponding to a distance to the traffic lane line from the imaging element; and
a detection reliability calculation element for calculating a degree of reliability of detection of the traffic lane line on the basis of the distance distribution of the edge intensity of the traffic lane line.
