Method for determining whether a vehicle can pass through an object by means of a 3-D camera
First Claim
1. A method of determining whether a vehicle can pass through or pass under an object, while the vehicle is driving on a roadway, wherein the roadway is part of a ground, said method comprising steps:
- with a 3-D camera, recording at least one image of surroundings ahead of the vehicle, to provide image data;
ascertaining at least one trajectory along which the vehicle is likely to move;
from at least the image data of the 3-D camera, detecting an object that includes an upper portion located above the trajectory,from at least the image data of the 3-D camera, detecting whether the object includes at least one connection portion that connects the upper portion to the ground, from at least the image data of the 3-D camera, determining dimensions and a shape of a 2-dimensional entry area that is bounded vertically between the upper portion of the object and the roadway, and that is bounded laterally by any said connection portion that has been detected, anddetermining whether it is possible for the vehicle driving along the trajectory to pass through the 2-dimensional entry area by fitting vertically and laterally in the 2-dimensional entry area.

Abstract
A method and a device determine whether a vehicle can pass through a passage of an object, based on image data from a 3-D camera, which records an image of surroundings of the vehicle. A trajectory of the vehicle is ascertained. From the image data, it is determined whether an object located above the trajectory is recognized and whether the object has at least one connection to the ground. The dimensions and the shape of an entry area or a passage space between the object and the roadway, through which the vehicle is to pass, are determined from the image data. By comparing the dimensions and shape of the entry area or the passage space with the dimensions and shape of the vehicle, it is determined whether and how the vehicle can pass through the entry area or passage space.

21. A device for determining whether a vehicle can pass through or pass under an object, while the vehicle is driving on a roadway, wherein the roadway is part of a ground, said device comprising:
-
a 3-D camera configured and arranged to record at least one image of surroundings ahead of the vehicle; a circuit arrangement configured to ascertain at least one trajectory on which the vehicle is likely to move; a circuit arrangement configured to determine from the image data of the 3-D camera; whether an object is present that includes an upper portion located above the trajectory, and whether said object has at least one connection portion that connects the upper portion to the ground; and a circuit arrangement configured to determine, from the image data, dimensions and a shape of a 2-dimensional entry area bounded vertically between the upper portion of the object and the roadway, and to determine, from the dimensions and the shape of the entry area, whether it is possible for the vehicle driving along the trajectory to pass through the entry area.
