Abstract: A method for correcting a determination threshold of a floor medium and a method of detecting thereof are provided. The method is used for controlling a mobile robot equipped with a sound emitter and a sound receiver to detect and recognize the floor medium during a movement just started. A first detection result of a current floor medium is obtained by actively transmitting and receiving a sound signal, then, a to-be-adjusted detection result of the current floor medium is obtained only by passively receiving the sound signal through the sound receiver, and according to the similarity/difference of the two detection results, the determination threshold is corrected in the case of passively receiving the sound signal, so that the to-be-adjusted detection result is determined to be consistent with the first detection result.

Abstract: The disclosure relates to a video monitoring method for mobile robot. The method includes the following steps: providing one or more private area on a basis of a map constructed by a mobile robot; determining, on a basis of a position of the mobile robot and an image shot from a shooting angle of a camera, whether an image shot currently contains private contents; if the image shot currently contains private contents, shielding the private contents contained in the image; and if the image shot currently is not containing private contents, continuing monitoring the mobile robot. By providing one or more private area in a map constructed by a mobile robot, the mobile robot can determine whether a shot image contains private contents during the subsequent video monitoring process, so as to shield the private contents in the image, thereby ensuring the security in video monitoring of the mobile robot, and avoiding privacy leakage.
