Claims15
A method for calibrating sensor information of a vehicle, wherein the vehicle comprises at least one sensor of a first sensor type and at least one sensor of a second sensor type which is different from the first sensor type, the method comprising the following steps:
- detecting the environment during the movement of the vehicle by at least one sensor of the first sensor type and providing first sensor information by the at least one sensor of the first sensor type;
- detecting the environment during the movement of the vehicle by at least one sensor of the second sensor type and providing second sensor information by the at least one sensor of the second sensor type;
- creating a first three-dimensional representation of environment information from the first sensor information;
- creating a second three-dimensional representation of environment information from the second sensor information;
- comparing the first and second three-dimensional representations of environment information or information derived therefrom;
- determining differences between the first and second three-dimensional representations of environment information or information derived therefrom;
- calculating corrective information on calibration parameters of at least one sensor based on the determined differences;
- calibrating the sensors of the vehicle relative to one another based on the calculated corrective information.
A driver assistance system for a vehicle having a sensor of a first sensor type and at least one sensor of a second sensor type which is different from the first sensor type, wherein the driver assistance system is configured to carry out the following steps:
- detecting the environment during movement of the vehicle by at least one sensor of the first sensor type and providing first sensor information by the at least one sensor of the first sensor type;
- detecting the environment during the movement of the vehicle by at least one sensor of the second sensor type and providing second sensor information by the at least one sensor of the second sensor type;
- creating a first three-dimensional representation of environment information from the first sensor information;
- creating a second three-dimensional representation of environment information from the second sensor information;
- comparing the first and second three-dimensional representations of environment information or information derived therefrom;
- determining differences between the first and second three-dimensional representations of environment information or information derived therefrom;
- calculating corrective information on calibration parameters of at least one sensor based on the determined differences;
- calibrating the sensors of the vehicle relative to one another based on the calculated corrective information.
