The processor calculates one-dimensional depth information according to the image of the line pattern and calculates two-dimensional depth information according to the image of the speckle pattern.

The present disclosure provides a method and a device for determining a region to be cleaned, a dust cleaning apparatus, a terminal for controlling a cleaning robot, and a storage medium. The method includes: determining, in an initial image of a photovoltaic panel, a gap region associated with a gap between cell pieces; assigning first preset values to pixel values of pixels located in the gap region of the initial image to obtain a first value-assigned image, wherein the first preset values are pixel values of pixels in the initial image that correspond to the cell pieces.

A docking method executable by a mobile device is provided. The docking method includes obtaining a stored target location of a docking station, and navigating to the target location. The docking method also includes: during the navigation and/or at the target location, based on a determination that a guidance signal is not detected, performing a regional search. The docking method also includes: during the navigation, or at the target location, or during the regional search, based on a determination that the guidance signal is detected, moving, under the guidance of the guidance signal, to the docking station. Performing the regional search includes determining a basic search zone, searching for the guidance signal while moving along boundaries of the basic search zone, and based on a determination that the guidance signal has not been detected when a termination condition is satisfied, terminating the regional search.

An optical navigation device comprising: a processing circuit; a first light source, configured to emit first light; a cover; at least one second light source, configured to emit second light toward the cover; and an first optical sensor, configured to sense first optical data generated according to the first light and to sense second optical data generated according to the second light on the cover. The processing circuit determines a dirtiness level of the cover based on the second optical data sensed by the first optical sensor. The optical navigation device can further comprise a second optical sensor. Also, an optical navigation device which can avoid the interference of another optical navigation device is also disclosed.

A cleaner includes a body forming an external appearance, and a spin-mop cleaning module configured to support the body and including at least one spin-mop provided so as to come into contact with a floor while rotating in a clockwise direction or in a counterclockwise direction when viewed from an upper side. The inclination angle of a lower surface of the spin mop is changeable relative to a horizontal plane.

A robotic cleaner includes a cleaning assembly for cleaning a surface and a main robot body. The main robot body houses a drive system to cause movement of the robotic cleaner and a microcontroller to control the movement of the robotic cleaner. The cleaning assembly is located in front of the drive system and a width of the cleaning assembly is greater than a width of the main robot body. A robotic cleaning system includes a main robot body and a plurality of cleaning assemblies for cleaning a surface. The main robot body houses a drive system to cause movement of the robotic cleaner and a microcontroller to control the movement of the robotic cleaner. The cleaning assembly is located in front of the drive system and each of the cleaning assemblies is detachable from the main robot body and each of the cleaning assemblies has a unique cleaning function.

A movable electronic apparatus includes a mobile apparatus body, a contact-type detection apparatus and a control circuit. The mobile apparatus body is provided with an electrical drive assembly that drives the mobile apparatus body to move; the contact-type detection apparatus is mounted on the mobile apparatus body, and the contact-type detection apparatus is configured and when the contact-type detection apparatus contacts dispersed dirt, an electrical signal outputted by the contact-type detection apparatus changes; the control circuit is mounted on the mobile apparatus body, and the control circuit is configured to determine whether the dispersed dirt is detected according to the magnitude of the amount by which the electrical signal outputted by the contact-type detection apparatus changes, and to control the electrical drive assembly to drive the mobile apparatus body to execute a dirt dispersion prevention action when determined that dirt that may be dispersed is detected.

A cleaner includes a body which forms an outer appearance; a mop module having at least one rag part which is provided to wipe a floor while rotating; and a detaching module comprising at least one catching portion which detachably catches the mop module to the body, and a manipulation button which is exposed outside, wherein when the manipulation portion is touched, the catching portion releases catching of the mop module.

A mobile floor cleaning robot includes a body defining a forward drive direction, a drive system, a cleaning system, and a controller. The cleaning system includes a pad holder, a reservoir, a sprayer, and a cleaning system. The pad holder has a bottom surface for receiving a cleaning pad. The reservoir holds a volume of fluid, and the sprayer sprays the fluid forward the pad holder. The controller is in communication with the drive and cleaning systems. The controller executes a cleaning routine that includes driving in the forward direction a first distance to a first location, then driving in a reverse drive direction a second distance to a second location. From the second location, the robot sprays fluid in the forward drive direction but rearward the first location. The robot then drives in alternating forward and reverse drive directions while smearing the cleaning pad along the floor surface.

An autonomous cleaning device is provided. The autonomous cleaning device includes: a device body; and a drive module, a cleaning module and a sensing module, wherein the drive module, the cleaning module and the sensing module are detachably assembled to the device body, respectively.
