Identification of the object motion trajectory in a digital image using the Kalman filter

Piątkowski Tomasz

Journal of Automation, Electronics and Electrical Engineering

2023

Vol. 5, No. 3

31--45

The paper concerns identification of the object motion trajectories in a digital image. An image analysis procedure was used consisting of two methods: BLOB identification and Kalman filter. BLOB identification is the superior method, and the Kalman filter is an alternative one, used to determine the motion trajectories only in the event of incorrect BLOB identification. Data from the correct BLOB identification are used on an ongoing basis in the process of training the Kalman filter. In this way, the filter becomes a model of a physical object that allows predicting the future state based on the object's current behaviour. The use of two complementary image analysis methods allows to determine the motion trajectories of the object's characteristic points in conditions of uneven scene lighting. The effectiveness of the method was confirmed in experimental rests.

Digital image stabilization for the experimental verification of object motion trajectories

Vol. 4, No. 2

The article presents digital stabilization procedure of the image recorded with a camera performing unintentional spatial movement in relation to the scene. This method consists in carrying out translational and rotational transformations and scaling all frames in relation to the first frame, using the tools of the Matlab environment. The image stabilization procedure allows to effectively improve the image to make it suitable for the analysis of the tracked objects trajectories on the scene, observed from the camera located on the rotor drone.

W artykule przedstawiono procedurę cyfrowej stabilizacji obrazu zarejestrowanego kamerą wykonującą niezamierzony ruch przestrzenny względem sceny. Metoda ta polega na przeprowadzeniu transformacji translacyjnej, obrotowej i skalowaniu wszystkich kadrów względem kadru pierwszego, wykorzystując narzędzia środowiska Matlab. Procedura stabilizacji obrazu pozwala skutecznie uzdatnić obraz, by nadawał się on do analizy torów ruchu śledzonych obiektów na scenie, obserwowanej z kamery umieszczonej na dronie wirnikowym.
