First Claim
Patent Images
1. An apparatus for detecting objects in one or more images captured by an image pickup device mounted on a vehicle, comprising:
- (a) memory on which is stored pixels of at least one image captured by the image pickup device; and
(b) a controller operatively coupled to the memory and adapted to compute velocity information for each pixel in the image;
extract those pixels having a velocity component based on the velocity information;
detect oblique lines composed of those extracted pixels having a velocity component; and
generate a signal indicative of a road boundary in the image based on the oblique lines.

Abstract
A device automatically detects boundary lines on the road from an image captured by a camera mounted on the vehicle. The device includes a controller that performs image processing on the image to compute the velocity information for each pixel in the image, and, on the basis of the computed velocity information for each pixel in the image, extracts the pixels that contain velocity information, detects the oblique lines formed by the extracted pixels, and detects the boundary lines on the road on the basis of the detected oblique lines.

19. An apparatus for detecting objects in one or more images captured by an image pickup device mounted on a vehicle, comprising:
-
(a) velocity information computing means for processing the image to compute velocity information for each pixel in the image; (b) pixel extracting means for extracting pixels having a velocity component on the basis of the velocity information of the pixels of the images computed by the velocity information computing means; (c) oblique line detecting means for detecting oblique lines made of pixels having a velocity component and extracted by the pixel extracting means; and (d) boundary line detecting means for detecting at least one boundary line on the road present in the image on the basis of the oblique line detected by the oblique line detecting means. - View Dependent Claims (20, 21, 22, 23, 24)
