Abstract 3D model of the ramp was created from projections captured on the videos. Virtual calibration markers with known coordinates of the centres were spread over the model covering the area of interest. The 3D DLT calibration procedure for the cameras (Abdel-Aziz and Karara, 1971) in Simi software can be performed by substituting the calibration videos with corresponding projections of the model and mapping the virtual markers. The projections shall be overlaid the respective movement videos from the cameras in order to obtain the precise alignment of the camera views. Comparison of the calibration results using the standard calibration procedure and the innovative method had shown that the difference in coordinate estimation with the two methods is within a measurement error.
