    Data Fusion considering ‘Negative’ Information for Cooperative Vehicles
    (Informatik 2007 – Informatik trifft Logistik – Band 2, 2007) Tischler, Karin; Vogt, Heike S.
    Negative information provides important additional knowledge that is not exploited for sensor data fusion tasks by default. This paper presents a new approach to incorporate such information about unoccupied, observed areas or missing measurements in the Kalman filtering process. For this purpose, a combination with a grid-based method is proposed to generate a visibility map. This enables a plausibility check and an enhanced understanding for the collaborative perception of the environment with multiple cognitive vehicles. Results from a realistic traffic simulation are presented.

    Information fusion for cooperative vehicles
    (INFORMATIK 2006 – Informatik für Menschen, Band 1, 2006) Tischler, Karin; Duchow, Christian; Hummel, Britta
    The cooperative perception by an inter-vehicle network promises a multitude of improvements for advanced driver assistance systems. First, for the simultaneous estimation of the vehicle ego pose and the road network infrastructure, we propose a local, highly model-based fusion architecture for digital map and video information. Second, to extend the vehicle's field of view, we include remote information concerning the state of each participating vehicle and its object detections. For the object-level fusion of these detections a centralized tracking process by Kalman filtering is employed. The algorithms are evaluated in simulated vehicle network scenarios which are based on real sensor data.
