Abstract
An image processor for an automotive vehicle includes: an imaging element for capturing an image of a road; a traffic lane line detection element for detecting a position of a traffic lane line by determining an edge of the traffic lane line; a distance distribution calculation element for calculating a distance distribution of an edge intensity 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.
Claims17
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.
An image processor for an automotive vehicle comprising:
- an imaging element for imaging a road, on which the automotive vehicle is disposed;
- 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 an image of the road;
- a distance distribution calculation element for calculating a distance distribution of a number of edge detection times of the traffic lane line detected by the traffic lane line detection element, 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 number of edge detection times.
