Abstract
A computer implemented method for estimating a height profile of a road around a vehicle, comprises the following steps carried out by computer hardware components: receiving radar responses captured by a radar sensor mounted on the vehicle; determining an elevation spectrum of the road around the vehicle based on the radar responses; and estimating the height profile based on the elevation spectrum.
Claims20
A computer implemented method for estimating a height profile of a road around a vehicle,
- the method comprising the following steps carried out by computer hardware components:
- receiving radar responses captured by a radar sensor mounted on the vehicle;
- determining an elevation spectrum of the road around the vehicle based on the radar responses;
- estimating the height profile based on the elevation spectrum;
- and
- controlling an operation of the vehicle based on the height profile of the road around the vehicle;
- wherein:
- the elevation spectrum is a function over elevation and range or is discretized in a grid with axes range and elevation;
- and
- the elevation spectrum has as one axis the elevation as angle.
A system for estimating a height profile of a road around a vehicle, the system comprising computer hardware components configured to:
- receive radar responses captured by a radar sensor mounted on the vehicle;
- determine an elevation spectrum of the road around the vehicle based on the radar responses;
- estimating the height profile based on the elevation spectrum;
- and
- control an operation of the vehicle based on the height profile of the road around the vehicle;
- the elevation spectrum is a function over elevation and range or is discretized in a grid with axes range and elevation;
- and
- the elevation spectrum has as one axis the elevation as angle.
A non-transitory computer readable medium storing instructions that, when executed by computer hardware components, configure the computer hardware components to estimate a height profile of a road around a vehicle, by:
- receiving radar responses captured by a radar sensor mounted on the vehicle;
- determining an elevation spectrum of the road around the vehicle based on the radar responses;
- estimating the height profile based on the elevation spectrum;
- control an operation of the vehicle based on the height profile of the road around the vehicle;
- wherein:
- the elevation spectrum is a function over elevation and range or is discretized in a grid with axes range and elevation;
- and
- the elevation spectrum has as one axis the elevation as angle.
