Estimating the Error in Locating Fiducial Markers in Space Using Physical Simulation

One of the ways to estimate the error of being designed optical measurement systems is computer simulation, including simulation of images for computer vision systems. However, in order to use the results of such simulation it is necessary to verify them. For such verification, the paper proposes to use the results of physical simulation. In order to verify the previously developed system of computer simulation of images with fiducial markers, an experimental study is conducted to estimate the error in determining the position of ArUco markers in space. The paper presents the developed experimental setup and the technique of physical simulation. The experimental study consisted in determining the dependence of the absolute error in determining the marker position on the size of the marker in the image. The comparison of the results of the computer and physical simulation allowed to verify the previously developed computer simulation system.
