Robust Video/Ultrasonic Fusion-Based Estimation for Automotive Applications
In this paper the authors improve object tracking with robust estimation using either stationary or non-stationary cameras for applications in collision avoidance for vehicles utilizing Intelligent Transportation Systems (ITS)-developed technologies. By employing a robust extended Kalman filter (REKF) as well as increasing spatial diversity from multiple cameras, uncertainties in object recognition can be reduced. While optical flow based segmentation techniques for object segmentation provide similar results, the use of normal flow based segmentation provides a faster response time. It is also shown that the presented system provides better results when subjected to large uncertainties in the visual data. By using ultrasound cameras fused with standard video capture and applying REKF as opposed to only extended Kalman filtration (EKF), results were improved substantially.
