Driver's aid using image processing

A system for alerting a driver of an automobile to a traffic condition, the system comprising:

• at least one camera having a field of view and facing in the forward direction of the automobile, said at least one camera capturing images of the field of view in front of the automobile;
• a control unit for receiving the images of the field of view captured by the at least one camera, said control unit identifying objects of at least one predetermined type in the captured images, and analyzing the identified objects to determine whether any of the identified objects present a condition requiring a response by the driver;
• and
• a display for receiving control signals from the control unit regarding one or more of said identified objects which have been determined to present a condition requiring a response by the driver, and for displaying an image of said one or more of said identified objects to the driver, said displayed image being positioned and scaled so that said displayed image overlays a corresponding actual object as seen by the driver, the displayed image of the object enhancing a feature of the corresponding actual object to alert the driver,
• wherein the control unit identifies objects of at least one predetermined type in the captured images are pedestrians in the image, and the control unit determines whether the pedestrian and the automobile are on a collision course.

• wherein the system comprises two cameras each facing in the forward direction of the automobile from different positions and each having a different respective field of view, the two cameras each capturing images of their respective field of view in front of the automobile.

A method for alerting a driver of an automobile to a traffic condition, the method comprising the steps:

• capturing images of a field of view in front of the automobile;
• identifying objects in the images of at least one predetermined type, and analyzing the objects to determine whether one or more of the identified objects present a condition that requires a response of the driver;
• and
• displaying to the driver an image of at least one of the identified objects requiring the driver's response, the displayed image being positioned and scaled so that displayed image of the object overlays a corresponding actual object as seen by the driver, the displayed image of the object enhancing a feature of the corresponding actual object to alert the driver,
• wherein the step of identifying objects in the image of at least one predetermined type and analyzing the objects to determine whether one or more of the identified objects present a condition that requires the driver's response, includes identifying at least one of pedestrians and other automobiles in the image, and determining whether any identified pedestrians and other automobiles are on a collision course with the automobile.
