VIDEO BASED INTELLIGENT VEHICLE CONTROL SYSTEM
First Claim
1. A system for longitudinal and lateral control of a vehicle, the system comprising:
- a camera generating a plurality of images representative of a field of view in front of the vehicle; and
a controller receiving the plurality of images anddetecting an object in the plurality of images,extracting a plurality of features from the plurality of images,generating a plurality of edges connecting pairs of the plurality of features, a length of the edges representing a spatial distance between the plurality of features;
generating a reference feature depiction based on the plurality of features and the plurality of edges from one or more of the plurality of images,generating a comparison feature depiction based on the plurality of features and the plurality of edges from one of the plurality of images,comparing the reference feature depiction and the comparison feature depiction, anddetermining a longitudinal position of the vehicle relative to the object based on differences between the reference feature depiction and the comparison feature depiction.

Abstract
A system for longitudinal and lateral control of a vehicle. The system includes a camera generating a plurality of images representative of a field of view in front of the vehicle, and a controller receiving the plurality of images. The controller detects an object in the plurality of images, extracts a plurality of features from the plurality of images, generates a reference feature depiction based on the plurality of features from one or more of the plurality of images, generates a comparison feature depiction based on the plurality of features from one of the plurality of images, compares the reference feature depiction and the comparison feature depiction, and determines a longitudinal position of the vehicle relative to the object based on differences between the reference feature depiction and the comparison feature depiction.

18. A method of controlling a vehicle using a forward looking camera, the method comprising:
-
detecting an object in a plurality of images generated by a camera, extracting a plurality of features from the plurality of images, generating a plurality of edges connecting pairs of the plurality of features, a length of the edges representing a spatial distance between the plurality of features; generating a reference feature depiction based on the plurality of features and the plurality of edges from one or more of the plurality of images, generating a comparison feature depiction based on the plurality of features and the plurality of edges from one of the plurality of images, comparing the reference feature depiction and the comparison feature depiction, and determining a longitudinal position of the vehicle relative to the object based on differences between the reference feature depiction and the comparison feature depiction. - View Dependent Claims (19, 20, 21, 22, 23)
