A new camera calibration method based on two 1-D targets is proposed to solve the calibration problem of camera with large field of view,which only requires the camera to observe two arbitrarily placed 1-D targets from several different viewpoints.First,the target images are undistorted using the co-linearity of the feature points on 1-D target.Then the vanishing point of the spatial line defined by each 1-D target is computed,and the angle between two 1-D targets is expressed using the camera intrinsic par...
