Abstract
A cleaning system includes a self-driving cleaning robot and a charging station with a reference marker. The cleaning robot has an optical detection unit by way of which it detects the reference marker. The cleaning robot has a computing unit that is connected for communication purposes to the detection unit and a control unit for controlling the cleaning robot. The computing unit controls the approach of the cleaning robot to the charging station in a distance-dependent and in a detection-dependent manner using a histogram of oriented gradients and using the reference marker. A HOG method and a reference marker method can thus be used in combination for improved navigation.
