Abstract: The invention relates to a method and to a device for determining whether a vehicle can pass through an object by means of a (spatially resolving) 3-D camera. At least one image of the surroundings of the vehicle is recorded by a 3-D camera. At least one trajectory is ascertained on which the vehicle is likely to move. From the image data of the 3-D camera it is determined whether an object located above the trajectory is recognized and whether said object has one or more connections to the ground. For a corresponding object the dimensions and shape of the area or space between said object and the roadway through which the vehicle is to pass according to the trajectory are determined from the image data. By comparing the dimensions and shape of the entry area or the space which can be passed through with the dimensions and shape of the vehicle, it is determined whether and how the vehicle can pass through the object, and further suitable actions can be taken.

Abstract: The use of widely separated and coordinated cameras allows trains to recognize obstructions and calculate distance to them to a degree which enables them to react quickly and brake early enough to avoid accidents. This applies to hazards such as fallen trees, stalled cars, people, and other trains on the rails. The system can also apply to crossings, enabling them to see approaching trains and gauge their distance, velocity, and deceleration, so that they can be shut down early and alarms sounded immediately. These systems are autonomous, using software which allows trains to know exactly where they are and at what speed they are travelling independently of external signals, including GPS, allowing a measure of safety beyond normal communications. These systems can also work in the infra-red, allowing compensation for fog and rain.
