Method for detecting objects in the surroundings of a vehicle by determining coverage of the objects, computing device, and sensor system
View Patent ↗A method for detecting objects in the surroundings of a vehicle includes receiving sensor data which describe the objects in the surroundings from a surroundings sensor of the vehicle; determining each of the corners of the objects, with the corners describing outer delimitations of each object; determining a relative position of each of the corners to the surroundings sensor; sorting the determined corners in a predetermined angle direction; checking, for each of the corners in the angle direction, whether the corners are covered by another of the objects, on the basis of the relative position of each of the corners to the surroundings sensor; and determining regions of each of the objects that can be detected by the surroundings sensor, on the basis of checking the corners.
1. A method for capturing objects in a surrounding area of a vehicle, the method comprising:
receiving sensor data describing the objects in the surrounding area from a vicinity sensor of the vehicle,
determining corners of the objects, wherein respective corners describe outer boundaries of a respective object,
determining a relative orientation of the corners in relation to the vicinity sensor,
arranging the corners in order in a predetermined angle direction,
checking each of the corners along the angle direction as to whether each of the corners is obscured by another of the objects, based on the relative orientation of the corners in relation to the vicinity sensor, and
determining regions of the respective objects that are capturable for the vicinity sensor based on the checking of the corners.
2. The method according to claim 1 , further comprising:
determining a proportion of the respective objects which is located in a capture region of the vicinity sensor,
wherein the capturable regions are determined in dependence on the proportion.
3. The method according to claim 1 , further comprising:
determining an obscuration list in which the respective objects are entered in dependence on a relative orientation of their corners in relation to the vicinity sensor, wherein the obscuration list is updated during the checking of the corners along the angle direction.
4. The method according to claim 1 , wherein:
for determining the capturable regions of the respective objects, an angle list is determined which describes capturable angle regions of the respective objects, and
the angle list is updated during the checking of the corners along the angle direction.
5. The method according to claim 1 , wherein the corners of the objects are determined in polar coordinates.
6. The method according to claim 1 , further comprising:
determining a probability of existence for the respective objects in dependence on the capturable regions of the respective objects.
7. A computing device for a sensor system of a vehicle, wherein the computing device is configured for carrying out the method according to claim 1 .
8. A sensor system for a vehicle, comprising:
the computing device according to claim 7 , and
at least one vicinity sensor.
9. A computer product comprising a non-transitory computer readable medium having stored thereon program code which, when executed by a computing device, carries out the method according to claim 1 .
