A new robust algorithmic for multi-camera calibration with a 1D object under general motions without prior knowledge of any camera intrinsic parameter

► We address the multi-camera calibration problem with a 1D object that moves freely. ► Camera calibration is necessary when the retrieval of 3D information is required. ► The proposed algorithm does not require prior knowledge of the camera parameters. ► Experiments show that the method is suitable even in the presence of noise.
