Abstract
A method for evaluating sensor data. In the method, firstly, raw sensor data and/or processed sensor data from at least one sensor are input and measurement data determined from the raw sensor data and/or the processed sensor data. The measurement data are then corrected on the basis of a mathematical model, wherein, on correction, drift of the raw sensor data and/or of the processed sensor data is determined and removed from the measurement data. The corrected measurement data are furthermore output.
Claims9
A method for evaluating sensor data, the method comprising the following steps:
- inputting raw sensor data and/or processed sensor data from at least one sensor;
- determining measurement data from the raw sensor data and/or the processed sensor data;
- correcting the measurement data based on a mathematical model, wherein the measurement data is corrected either when a check of a change in a sensor alignment reveals that the sensor alignment has changed or when a check of an intensity of a sensor movement reveals that an intensity of the sensor movement exceeds a predetermined value, and wherein, on correction, drift of the raw sensor data and/or of the processed sensor data is determined and removed from the measurement data;
- and
- outputting the corrected measurement data.
