Technique applicable to detecting vehicles
First Claim
1. A system for detecting a spot of light generated from a lamp of other vehicles other than an instant vehicle equipping the system, the system comprising:
- an imaging device imaging a forward view of the instant vehicle and outputting a first image data of the view;
a detector detecting, from the first image data, a second image data indicating a line on a road, the line running along the road on which the instant vehicle and the other vehicles are present;
a filter filtering the first image data to remove therefrom a noise consisting of image data other than the spot of light; and
an output member outputting a signal filtered by the filter, the a signal indicating the spot of light.

Abstract
A vehicle detection system can reduce erroneous detection of light spots originated from vehicle tail lamps as being those originated from disturbing light sources, such as reflectors on the roadside, in the image data picked up by an image pickup means, such as a camera. Where light spots, or bright areas, originated from some light sources are present in the image data, detection is performed as to whether or not the light spots are a row of light spots originated from reflectors, referring to the location of a partition line defining the lane where the instant vehicle travels. If the light spots are regarded as being the row of light spots originated from the reflectors, these light spots are deleted from the objects to be detected in performing detection of the light spots originated from other vehicle lamps.

10. A method for detecting a spot of light generated from a lamp of other vehicles other than an instant vehicle, the method comprising:
-
imaging a forward view of the instant vehicle and outputting a first image data of the view; detecting, from the first image data, a second image data indicating a line on a road, the line running along the road on which the instant vehicle and the other vehicles are present; filtering the first image data to remove therefrom a noise consisting of image data other than the spot of light; and outputting a signal filtered by the filter, the a signal indicating the spot of light. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A program product for detecting a spot of light generated from a lamp of other vehicles other than an instant vehicle, a program of the program product comprising the steps of:
-
imaging a forward view of the instant vehicle and outputting a first image data of the view; detecting, from the first image data, a second image data indicating a line on a road, the line running along the road on which the instant vehicle and the other vehicles are present; filtering the first image data to remove therefrom a noise consisting of image data other than the spot of light; and outputting a signal filtered by the filter, the a signal indicating the spot of light. - View Dependent Claims (20)
