Claim:
1. An automotive forward-looking system comprising: a forward-looking sensor that has a field of view in a predetermined range of angle and monitors a forward area of a vehicle; a controller that calculates a turning angle of the forward-looking sensor by estimating a curvature of a curved road, wherein the controller estimates the curvature of a curved road on the basis of a guardrail installed at a side of the curved road; a sensor turning unit that turns the forward-looking sensor by being controlled to operate by the controller; and a guardrail detector that calculates a first curvature on the basis of the guardrail, wherein the guardrail detector divides a depth image provided from the forward-looking sensor for each of heights and removes a ground section, removes an object area on a basis of location information of the vehicle in the forward area provided by an object recognizing/tracing unit, and calculates the first curvature by fitting a 3D-curve or curved surface on the depth image with the object area removed.
