Abstract:
A calibration method may include: detecting, by a lane detection unit, lanes from around images acquired through cameras of a vehicle, when a behavior of the vehicle satisfies a preset behavior condition; analyzing, by a valid lane extraction unit, statistical characteristics of the positions and directions of the detected lanes, and extracting a valid lane by removing a misdetected lane; and estimating, by a parameter estimation unit, installation angles of the cameras based on the direction of the valid lane and a vanishing point decided through the valid lane.

Claim (Index 10):
The calibration method of  claim 9 , wherein in the reestimating of the pitches and yaws of the front and rear cameras through the LM,\n the parameter estimation unit converts the calibrated straight lines into front/rear valid lanes on the bird's-eye view, using a rotation matrix of the front and rear cameras which is calculated during the reestimation process through the LM, and reestimates the pitches and yaws of the front and rear cameras such that the front/rear valid lanes are parallel to a first-direction reference axis on the bird's-eye view, and parallel to each other.
