W artykule opisano sposób optycznej rejestracji i pomiaru odchyleń różnic toru ruchu kolejnych przejazdów autonomicznego pojazdu sterowanego programem komputerowym. Do oszacowania odchyleń zastosowano elementy rozszerzonej rzeczywistości oraz obrazy zarejestrowane kamerą. Zaproponowano miarę różnic kreślonego toru ruchu w postaci pola powierzchni, którego kontur wyznaczają kolejne tory przejazdów. Wykazano, że wielkość pola rośnie wraz ze wzrostem mocy silników napędowych pojazdu.

The paper describes a method for optical recording and measurement of trajectory deviations of an autonomous vehicle. A model of the vehicle was built from a system of Lego blocks (Fig. 1), computer-programmed within a task system. The model applied belongs to special vehicles of the rover class [2]. The program providing for its motion along an 8-shaped track, with a parking option (Fig. 3), was prepared in the LabView system (Fig. 2) and inserted in the vehicle-steering module by means of wireless technology. The program consists of a sequence of motion commands along sections, as well as turns separated from each other by mini breaks. It was observed that each time the model motion track was different from the previous one. To estimate the deviation from the track in successive runs, elements of augmented reality were used, imposing a pattern of dimensioned grid upon the camera-registered image (Fig. 4). After advanced graphical transformations (image correction, charting the trajectory, vectorisation and Boolean arithmetic) a generalised measure of the differences of the charted motion track was obtained in the form of the surface of the area whose contour was marked by the individual tracks. It was shown that the size of the surface grew along with the power of the engines propelling the model. This results from the skidding of the wheels on the ground due to the multiple acceleration and breaking (mini breaks in the program sequences) as well as from turning. Further research will concern designing a program improving the model trajectories.
