| Zusammenfassung: | A navigation device includes an image sensor, a memory unit and a processing unit. The image sensor is configured to capture an image frame of a work surface. The memory unit previously saves a lookup table including surface quality profiles of different surface categories. The processing unit is configured to calculate surface qualities of the work surface associated with different quality thresholds and to compare the surface qualities with the lookup table to determine the surface category of the work surface thereby selecting a tracking strategy associated with the surface category of the work surface. |
