Techniques to Obtain Information About Objects Around a Vehicle
First Claim
1. A method for monitoring an area surrounding a host vehicle or objects external of the host vehicle during movement of the host vehicle under control of an occupant in the host vehicle, the host vehicle having a frame defining a compartment that accommodates the occupant of the host vehicle who is able to guide movement of the host vehicle when present in the compartment, the method comprising:
- projecting light into an area of interest external to the host vehicle from at least one light source on the host vehicle;
detecting reflected light at at least one camera arranged on the host vehicle at a position different than the position of the at least one light source and at a position from which light reflected from any objects in the area of interest in the exterior of the host vehicle is received;
analyzing the reflected light relative to the projected light to obtain information about a distance between the host vehicle and objects located in the area of interest and motion of the objects located in the area of interest; and
causing an action on the vehicle based on the obtained information about the distance and motion.

Abstract
Method for monitoring an area surrounding a host vehicle or objects external of the vehicle includes projecting light into an area of interest external to the vehicle from one or more light sources on the vehicle, detecting reflected light at at least one camera on the vehicle at a position different than the position from which the light is projected and at a position from which light reflected from any objects in the area of interest in the exterior of the vehicle is received and analyzing the reflected light relative to the projected light to obtain information about a distance between the vehicle and objects located in the area of interest and/or motion of the objects located in the area of interest. Then, one or more actions are undertaken on the vehicle based on the information about the distance and motion of the external object.
