Abstract: A computer-implemented method of assisting in the operation of a vehicle is disclosed, the method comprises the steps of: with at least one sensor, sensing an environment of the vehicle thereby obtaining sensor data, and deriving spatial information of the environment and semantic information from the sensor data. Furthermore, generating a dynamic occupancy grid model, in which the sensed environment is represented as a grid consisting of a plurality of grid cells, the grid cells comprising occupying information and a dynamic state represented by a set of particles, and assigning the grid cells and the particles semantic information derived from the sensor data, wherein the semantic information is represented by a set of categories.

Abstract: Tracking systems using multi-object-tracking (MOT) combine data from a plurality of sensors (101) to derive a state estimate of one or more objects (103) are described. The interfaces to the sensors (101) are such that different ones of the sensors (101) can be used. The tracking (102) in the system consists of different blocks for state estimation (104), object's existence estimation (106), and data association (105). To utilize the data of a sensor, the sensor data and the system which is observed is modeled using the Bayesian filtering framework. All interfaces of the system, i.e. the interfaces between the sensors (101) and the MOT system as well as of the blocks in the MOT are of a characteristic that ensures that only compatible models are used with each other already when designing the system.
