Abstract
A method, and corresponding radar system, for calibrating a radar sensor, including: placing at least one reference object at a predetermined position in the field of view of the radar sensor; sensing an estimated position of the at least one reference object by way of the radar sensor; calculating a correction value for the position of the at least one reference object based on the predetermined position of the at least one reference object and on the estimated position, sensed by the radar sensor, of the at least one reference object; and applying the calculated correction value to estimated positions, sensed by the radar sensor, of further objects in the field of view of the radar sensor.
Claims8
A method for calibrating a radar sensor, comprising:
- placing at least one reference object at a predetermined position in the field of view of the radar sensor;
- sensing an estimated position of the at least one reference object by the radar sensor;
- calculating a correction value for the position of the at least one reference object based on the predetermined position of the at least one reference object and on the estimated position, sensed by the radar sensor, of the at least one reference object;
- and
- applying the calculated correction value to estimated positions, sensed by the radar sensor, of further objects in the field of view of the radar sensor;
- wherein an area to be monitored by the radar sensor is predetermined, and wherein at least two reference objects are placed in the area to be monitored;
- and
- wherein upon the calculation of a correction value, the difference between the actual height of each reference object and the estimated height, sensed by the sensor, of the respective reference object is calculated, and wherein a discrepancy plane is created from the calculated differences.
A radar system, comprising:
- a radar sensor;
- and
- a control device for calibrating the radar sensor, by performing the following:
- placing at least one reference object at a predetermined position in the field of view of the radar sensor;
- sensing an estimated position of the at least one reference object by the radar sensor;
- calculating a correction value for the position of the at least one reference object based on the predetermined position of the at least one reference object and on the estimated position, sensed by the radar sensor, of the at least one reference object;
- and
- applying the calculated correction value to estimated positions, sensed by the radar sensor, of further objects in the field of view of the radar sensor
- wherein an area to be monitored by the radar sensor is predetermined, and wherein at least two reference objects are placed in the area to be monitored;
- and
- wherein upon the calculation of a correction value, the difference between the actual height of each reference object and the estimated height, sensed by the sensor, of the respective reference object is calculated, and wherein a discrepancy plane is created from the calculated differences.
